Effect of color filters on photo electrochemical solar cell of pure and rhenium doped SnSe crystals

Applications of photo functional materials have universally aroused tremendous interest in recent years. The development of photo electrochemistry as a field of science was stimulated by the need for developing a photo electrochemical (PEC) energy conversion as a novel technique to utilize the infinite source of energy. Here, we have demonstrated the effect of different color filters on PEC behavior on rhenium doped tin mono selenide crystals synthesized by direct vapor transport technique. Authors have been used as grown SnSeRex (x = 0, 0.1, 0.2) crystals for photo electrode in PEC solar cell. This cell has been investigated in detail to evaluate its parameters, e.g. short circuit current (I sc ), open circuit voltage (V oc ), efficiency (η) and fill factor (FF). The electrodes were prepared from further mentioned crystals showing absolutely plane faces obtained through the act of cleavage with help of an adhesive tape. Illumination of light, the electrolyte and counter electrode were kept constant. This work intends to summarize PEC behavior in order to see the effect of rhenium doping and different color filter sheet on the mentioned single crystals on their parameters.
