... The energy of the sun is generated from the nuclear fusion of the of its hydrogen into helium, with its resulting mass depletion rate of approximately of tons per seconds and a tremendous release of heat and light [1]. Solar energy being transmitted from the sun to through space to earth by electromagnetic radiation must be converted to heat before it can be used for practical heating or cooling [2]. This energy is relatively dilutes, therefore the size of a system used to convert it on a practical scale must be relatively large. ...

A solar water heater is one of the ways through which sunlight energy can be harnessed for domestic use. The performance of a typical solar water heater made from locally available materials was determined and in the process a solar water heater is designed, construct and tested on the university of Maiduguri campus. The sunlight energy is absorbed by the collector made up of an aluminum absorber plate enclosed within a transparent cover to prevent the emitted radiation from escaping (greenhouse effects). The absorber is made with fluid carrying tubes to absorb heat and increases the temperature of the water in the tank through theromsyphon principle. Maximum fluid output temperature and the collector temperature of 59 and 70 respectively were obtained on a sunny day. This solar water heater find useful application as a source of hot water for cooking, washing and laundry, and acts as a renewable energy resources in regions where there is abundant sunlight.

A limitation of PV-based generation is its weather and daylight dependence. Therefore, researchers motivated to study, design, and implement effective PV batteries-based systems that can viably energize targeted appliances. In the case of unstable PV output power, the switching towards a battery-based power supply should be effectively realized. Thus, the proposed system has the following aims: (1) To ensure that the maximum amount of sunlight will be absorbed by the PV panel during the hours that the sun shines in a particular area; (2) The level of soiling ratio is not above a certain threshold. Otherwise, a cleaning notification is generated and sent to the maintenance center; and (3) In case of any drop of PV output power, PV-to-battery source switching is employed in a viable manner, without causing any major disturbance or damage to the intended load. The solution is realized by developing an intelligent assembly of a digital controller with appropriate sensors and actuators network. The controller will work as a decision-maker. Based on sensors' feedback, it will command the actuator to orient PVs to absorb the maximum possible sunlight. Additionally, based on an updated weather parameters database, it can generate and automatically send cleaning notifications with the concerned PV coordinates. Moreover, it manages a stable load supply by effective switching between PV and battery power sources.

Among all the developed and developing countries, India is actively contributing to providing clean, affordable and sustainable energy to the citizens and making pace to achieve the UN Sustainable Development Goals 7 till 2030. In this regard, tremendous growth in solar energy generation has been observed in the Indian energy sector. The National Solar Mission targets to attain the goal of 100 GW upto 2022. The country's solar power potential is 748.99 Gwp. The total on-grid installed capacity is 47112.55 MW, with ground-mounted (i.e., solar power plants) accounting for 41001.49 MW and solar roofs accounting for the remaining 6111.06 MW. Solar power contributes a substantial share (41.68%) in the total annual (June 2020 to May 2021) electricity generation (147678.3 MU) from renewable sources. The rise in the overall solar installed capacity (25 MW to 48556.65 MW) in the last decade represents a massive growth in solar power in the country. India is located in the tropical and subtropical region, receives high intensity of solar radiation (200MW/km 2) and hence possesses more potential for energy to be harnessed. The present study provides insights into the country's existing solar energy potential, installed capacity and solar power generation to achieve goals in this sector. The potential states are categorized based on installed capacity (commissioned) through the atlas and statistical computation. Solar energy policies/schemes initiated by the Government of India are reviewed concerning the progress in the energy sector.

Solar energy as a means of power generation is yet to be fully utilized in Nigeria even if there is abundance of it all over the country. This work investigated the availability and utilization of solar energy resources in some selected geopolitical zones of the country. These include the northwest (Gumel), NorthEast (Maiduguri, Kumagunnam, Gamboru and Baga), North-Central (Pankshin and Biu), SouthWest (Lagos), South East (Ihiala) and South-South (Buguma). The annual solar radiation potentials from January-December 2021 as well as the air temperatures were determined for the seven locations under study. Retscreen-a renewable energy software was used for the simulation and analysis. The investigation revealed the annual electricity that can be generated for these Gumel located in NorthWest had 338,463MWh, while Maiduguri, Kumagunnam, Gamboru and Baga all located in NorthEast had 158,445MWh, 343,964MWh, 300,927MWh and 317,968MWh respectively. North-Central were Pankshin and Biu are located recorded 149,665MWh and 318,416MWh. SouthWest , SouthEast and South-South recorded 128,349MWh, 252,174MWh and 230,209MWh. The investigation has also revealed that of all the seven geographical locations under study, the NorthEastern part of the country is more favourable in terms of value obtained and the least favourable is SouthWest. The work has further shown that the abundance of electricity in these regions if fully tapped can be a huge source of income to even the neighbouring state or country.

CZTS solar cells have been utilized as a replacement for CIGS and CdTe solar cells in thin-film technology. With the better absorption coefficient of this material, it has achieved efficiency higher than 13%. In this work, the performance of a CZTS thin-film solar cell (TFSC) is analyzed by replacing intrinsic ZnO (i-ZnO) with Mg-doped ZnO as window layer material. i-ZnO has good optical and electrical characteristics, but the optical, electrical, and morphological characteristics of Mg-doped ZnO are more promising for its application as window layer material in CZTS thin-film solar cells. The electrical properties of the solar cell are analyzed in the Silvaco TCAD under AM 1.5G illumination. A sharp increase in the performance of the solar cell is observed. Because of the higher transmittance of Mg-doped ZnO, the current density increases. With varying thickness of the window layer and absorber layer, the results in this work reveal maximum efficiency of 19.57%. Variations in the current density (Jsc), open-circuit voltage (Voc), and fill factor (FF %) are also observed. The proposed structure of the thin-film CZTS solar cell shows good performance by enhancing its efficiency.

Parabolic trough solar collectors (PTSCs) are commonly used in solar thermal implementations to achieve high-temperatures. The current investigation looks at entropy formation and the effect of nano solid particles on a parabolic trough surface collector (PTSC) mounted aboard a solar-powered ship (SPS). The non-Newtonian first grade viscoelastic type, as well as a porous medium and Darcy-Forchheimer effects, were utilised in the current study. The flowing of PTSC was created by a non-linear stretching sheet, and the changing thermal conductivity, heat source, and viscous dis-sipation effects were used to calculate the heat flux in the thermal boundary layer. To convert partial differential equations (PDEs) into solvable ordinary differential equations (ODEs) with boundary-constraints, a similarity transformation strategy was used. The boundary-constraints and PDEs have been reduced to a set of non-linear ODEs (ordinary differential equations). To reach the approximated solution of ODEs, the Galerkin finite element method (G-FEM) is used. As working fluids, copper-sodium alginate (Cu-SA) and molybdenum disulfide-copper/ sodium alginate (MoS 2-Cu/SA) hybrid nanofluids were used. According to the findings, the perme-ability factor diminished the Nusselt number whilst boosting the skin friction factor. Furthermore,/home/eae overall entropy variance throughout the domain was increased for flow speeds using the Reynolds number, and viscosity changes were tracked using the Brinkman number. When compared to MoS 2-Cu/SA, using Cu-SA nanofluid boosted thermal efficiency by 1.3-18.8%.

The light from the Sun is a non-vanishing renewable source of energy which is free from environmental pollution and noise. It can easily compensate the energy drawn from the non-renewable sources of energy such as fossil fuels and petroleum deposits inside the earth. The fabrication of solar cells has passed through a large number of improvement steps from one generation to another. Silicon based solar cells were the first generation solar cells grown on Si wafers, mainly single crystals. Further development to thin films, dye sensitized solar cells and organic solar cells enhanced the cell efficiency. The development is basically hindered by the cost and efficiency. In order to choose the right solar cell for a specific geographic location, we are required to understand fundamental mechanisms and functions of several solar technologies that are widely studied. In this article, we have reviewed a progressive development in the solar cell research from one generation to other, and discussed about their future trends and aspects. The article also tries to emphasize the various practices and methods to promote the benefits of solar energy.

A solar cell is an electronic device which directly converts sunlight into electricity. Light shining on the solar cell produces both a current and a voltage to generate electric power. This process requires firstly, a material in which the absorption of light raises an electron to a higher energy state, and secondly, the movement of this higher energy electron from the solar cell into an external circuit. The electron then dissipates its energy in the external circuit and returns to the solar cell. A variety of materials and processes can potentially satisfy the requirements for photovoltaic energy conversion, but in practice nearly all photovoltaic energy conversion uses semiconductor materials in the form of a p-n junction. With regard to the development of sustainable energy, such as solar energy, in this article we will Study types of solar cells and their applications.

We present a comprehensive review on prospects for one-, two-, or three-dimensional nanostructure-based solar cells for manufacturing the future generation of photovoltaic (PV) modules. Reducing heat dissipation and utilizing the unabsorbed part of the solar spectrum are the key driving forces for the development of nanostructure-based solar cells. Unrealistic assumptions involved in theoretical work and the tendency of stretching observed experimental results are the primary reasons why quantum phenomena-based nanostructures solar cells are unlikely to play a significant role in the manufacturing of future generations of PV modules. Similar to the invention of phase shift masks (to beat the conventional diffraction limit of optical lithography) clever design concepts need to be invented to take advantage of quantum-based nanostructures. Silicon-based PV manufacturing will continue to provide sustained growth of the PV industry.
