QUANTUM EFFICIENCY, OPTICAL AND RECOMBINATION LOSSES IN THIN-FILM SOLAR CELLS BASED ON CU(IN,GA)SE2
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2014, Vol 11, Issue 4
Abstract
A theoretical analysis of the optical and recombination losses in thin film solar cells based on Cu(In,Ga)Se2 with band gap 1,36-1,38 eV are carried out. Based on the optical constants of the materials, the optical losses due to reflection at the interfaces and absorption in the layers of ZnO and CdS have been found. To calculate the recombination losses the spectral distribution of the quantum efficiency of CdS/CuIn1-xGax Se2 heterostructure is considered. From a comparison of calculated and experimental results, the real parameters of the solar cell and the losses due to the recombination of charge carriers at the front and back surfaces of the absorbing layer, in its neutral part and in the space charge region of p-n heterojunction have been determined.
