Electrodeposition is a low-cost and mature industrial technique for large-scale perovskite solar cells (PSCs) manufacturing. The present work provides new insights into developing compact and mesoporous electron transport layers for PSCs via the electrodeposition technique in one pot. By the precise control of current density and deposition duratio...
Lightweight and bendy plastic‐based perovskite solar cells (PSCs) are considered strong emerging rivals to the rigid heavy‐block photovoltaics made of conventional crystalline‐silicon. To further increase the competitiveness of these devices, the research community is nowadays searching for compatible, effective and scalable strategies to achieve e...
This chapter, entitled “Energy and Agriculture”, accounts for the energy demands of the agricultural sector, discussing, in brief, the main energy inputs at all stages of modern agricultural production and how they are usually managed up until today. The focus herein is to demonstrate the emerging eco-agricultural trend, presenting possible sustain...
“Solar photovoltaic energy in agriculture” is the main thematic content accounted for in the present book and the main topic for discussion in this chapter. For readers’ benefit and a comprehensive presentation of the current state of the art on the agrivoltaics approach, seven levels for discussion are considered. Initially, an introduction to agr...
The increasing demand for water, energy and food, due to population growth and urbanization, is aggravated by unprecedented extreme weather and climatic conditions. This situation is most likely to undermine the sustainable and peaceful development of humanity in the next years. Today, more than ever, there is an imperative need to support the iden...
This chapter is the forerunner of the cross-sectoral nexus approach of agrivoltaics that the present book introduces, presenting the current challenges on the Water-Energy-Food-Ecosystems (WEFE) nexus, as well as approaches that should be adapted in order to attain sustainable management of the WEFE nexus.
This chapter is a consolidated map of the future of agrivoltaics strategy, presenting the most significant emerging agrivoltaic concepts, from their design level to practical realizations, that appeared in the last few years. Emphasis is given to novel agrivoltaic concepts employing both the mature crystalline silicon photovoltaics and emerging sol...
This chapter accounts for an overview of solar cell technologies developed up to now, from the mature silicon-based solar cells to the third-generation photovoltaics. Herein, the most important characteristics, current challenges and strategies for further improvement of each solar cell technology are discussed, aiming to demonstrate possible manuf...
Inkjet‐printing is considered an emerging manufacturing process for developing perovskite solar cells (PSCs) with low material wastes and high production throughput. Up‐to‐now, all case studies on inkjet‐printed PSCs are based on the exploitation of toxic solvents and/or high‐molarity perovskite precursor inks that are known to enable the developme...
Currently, the topic of stability of perovskite solar cells (PSCs) has seized the paramount attention of the scientific community in the direction of achieving technological maturing for real-world applications. The present paper demonstrates a comprehensive investigation of the stability of carbon-based hole-transport-layer-free (C-based HTL-free)...
Inkjet‐printing technology is anticipated to play a forefront role in the future prototyping of perovskite solar cells (PSCs) to enable their ultra‐low‐cost and scalable manufacturing. However, key inkjet challenges related to fluid dynamics should be firstly addressed to allow the fabrication of high‐quality printed materials and subsequently comp...
Raw and modified fibrous clay minerals palygorskite (Pal) and sepiolite (Sep) were tested for their ability to remove ammonium from ammonium polluted water. Palygorskite and sepiolite underwent thermal treatment at 400°C (T-Pal and T-Sep respectively). Raw and thermally treated samples were characterized using XRD, SEM, BET, FTIR, TGA, zeta potenti...
In this work, natural palygorskite clay was coupled with TiO2 (anatase) nanocrystals to obtain nanocomposites, in order to be tested as photocatalysts for outdoor and indoor air de-pollution. Three types of palygorskite, i.e., untreated (P) and metal treated, namely Zn-modified (Zn-P) and Cu-modified (Cu-P) palygorskite, were firstly synthesized. A...
Up until now, the vast majority of perovskite solar cells (PSCs) have relied on the spin-coating of perovskite precursor solution under inert fully controlled conditions, with the performance of solar cells that are developed by alternative techniques and under an ambient atmosphere to lag far behind. This impedes the technology transfer from the l...
Given the present research momentum, the development of efficient and stable ambient air-processed perovskite solar cells (PSCs) is of the core interests of scientists dealing with perovskites for photovoltaics. Hitherto, many suitable approaches are proposed to this aim. However, according to the authors' knowledge, none of them deals with the stu...
“Polymer-in-salt” electrolytes are special conductive materials that demonstrate much higher conductivity compared to the conventional “salt-in-polymer” electrolytes. However, up-to-now, they are found unsuitable for dye-sensitized solar cells (DSSCs) application, mainly because they lead to increased charge recombination rate. The present paper de...
In the present investigation, a binary strategy for the development of wavelength-selective semi-transparent dye-sensitized solar cells (DSSCs), with a proper transmittance in the region of photosynthetic active radiation, for greenhouses-oriented applications is examined. Two new low-cost triphenylamine-based dyes and a highly transparent iodine-f...
For the first time in dye-sensitized solar cell (DSSC) technology, a di-carbazole-based dye was synthesized and evaluated for its usage as a potential sensitizer for the development of wavelength selective semi-transparent DSSCs for greenhouses-oriented applications.
