Abstract :
A study was made of properties of CuInSe2, CuInGaSe2 and CdZnS films and the performance of solar cells fabricated with these films. An efficiency of 10.5% for the cell with CuInSe2 film prepared by coevaporation and Cd1-xZn x S (x=0.19) film by EB evaporation was obtained. For the CuInGaSe2-based cell, an efficiency of 10.0% was obtained. PL emission spectra obtained on CuInSe2 films resulting in high-efficiency devices has two peaks in the range of 0.85-0.93 eV. For the low-efficiency CuInSe2 films, a single peak is observed at a higher photon energy
