This paper represents the investigation on growth of single crystals of Germanium Sulpho Selenide using Direct Vapour Transport Technique. The stoichiometries of the grown crystals have been analyzed using EDAX which shows that the grown crystals possess nearly stoichiometric proportion of starting material. The orthorhombic semiconducting compound GeS0.25Se0.75, GeS0.5Se0.5 and GeS0.75Se0.25 having various interesting electrical, optical and photoelectric properties. Using UV-VIS-NIR spectrophotometer optical absorption spectra of the crystals to obtain direct and indirect band gap of the material. Author has attempted to fabricate Photo Electro Chemical solar cell with grown mixed Germanium Sulphoselenide single crystals. Mott- Schottky plots have been used to study the energy band location and redox analysis of the material. This study justifies the appropriate choice of electrolyte for PEC work. The solar cell parameters e.g. the fill factor (FF), open circuit voltage (Voc), short circuit current (Isc) and efficiency (?) for all the cells have been calculated. All the results have been studied and implications have been discussed in the paper.
