Concentration is one of the primitive aspects in chemistry, which describes the extent of abundance of a solute in a given solution. Determining the concentration of a solution that does not has a chemical formula and with unknown molecular weight is one amongst the difficult topics. In this study, we have analyzed the concentration of such solutio...

The low-cost inorganic materials, KFeO2/ZnO, have been investigated as hole transport layer (HTL)/electron transport layer (ETL) and show better stability and high-power conversion efficiency for perovskite solar cell. Perovskite solar cells with two planar structures n-i-p and p-i-n have been fabricated using KFeO2 and ZnO showing 12.81% and 10.83...
lectrochemical double layer capacitors (EDLCs) which are fabricated using carbon based electrodes have been emerging at an alarming rate to fulfill the energy demand in the present day world. Activated charcoal has been accepted as a very suitable candidate for electrodes but its cost is higher than natural graphite. Present study is about fabricat...
Increment of the efficiency of dye-sensitized solar cells (DSSC) by an innovative type of photoanode consisting of a composite mixture of conventional P-25 titanium dioxide (P25-TiO2) nanoparticles and electrospun TiO2 nanofibers (EL TiO2 NF) with optimized weight ratio is obtained. This novel composite photoanode harvests sunlight more strongly co...

In general Dye-sensitized solar cell (DSSC) comprises of an electrode P-25 titanium dioxide (TiO2), sensitized with Ruthenium based Dye fabricated on a transparent substrate Fluorine doped Tin Oxide (FTO) glass, a Pt counter electrode and an electrolyte between the electrodes. This paper presents, the investigation of increment of photoelectric con...
Actuators based on conducting polymers are attracting increasing interest due to their desirable features such as large mechanical stress generated, sufficient maximum strain values, high reversibility, good safety properties and the possibility of precise control using small voltages. Many attempts have been made to improve the actuator performanc...
The demand for actuators based on conducting polymers is growing due to their highly desirable features such as large mechanical strength, high power density, sufficient maximum strain values, high reversibility and good safety properties. Many attempts have been made to improve the actuator performance. We report here some electromechanical measur...
Conducting polymer bilayers with poly(3,4-ethylenedioxythiophene) (PEDOT) and polypyrrole (PPy), each containing dodecyl benzenesulfonate (DBS) as immobile dopant species, were synthesized galvanostatically. The electrochemical behaviour of the bilayers was investigated using cyclic voltammetry, optical absorption spectroscopy and electrochemical q...
