What is it about?
Back contacts and interface defects related opto-electrical losses are still vital to limit its further technological benefit. TF PV cells shallow recombination and parasitic loss lessening purpose carrier selective back contact with band matching window layers are essential. Beside that back and front contact thickness choice is vital for field associated selective carrier collection and generous optical transmission into the active junction of the cell. It can make variation of cell efficiency. Window and front contact layers band edge variation and back contact thickness effect is analyzed by SCAPS-1D simulation software. ZnO and SnO 2 front contact for CdS and CdSe window layers effect are numerically studied for 1 μm CdTe thin film

Why is it important?
The optical design at the front and electrical design at the back is significant to improve opt--electrical gain. Moreover CdS thickness is important to control light and depletion width
