Optical and recombination losses in thin-film Cu(In,Ga)Se 2 solar cells

Loss mechanisms influence on Cu2ZnSnS4/CdS-based thin film solar cell performance

“…Finally, shading factors of 9% and 4% were found to fit experimental EQE T data for solar cells with record efficiencies. Similar values have been reported and considered for modeling CIGS solar cells [35,39].…”

“…For that purpose, experimental spectral dependences of the refractive index (n) and the extinction coefficient (j) for ZnO [35,36], CdS [37] and CZTS [38] were used. These n and j spectral dependences for ZnO and CdS materials have been also considered for modeling CIGS solar cells [39]. The absorption coefficient for each material as a function of wavelength can be calculated once electron and hole effective masses, band gap, and refractive index are known.…”

Optical and Recombination Losses in Cu2ZnSn(S,Se)4-Based Thin-Film Solar Cells with CdS, ZnSe, ZnS Window and ITO, ZnO Charge-Collecting Layers

“…Up to now, the optical and recombination losses in the SCs based on n-CdS/p-Cu(In,Ga)Se 2 , [13][14][15] n-CdS/ p-CdTe, 13 16-25 n-ZnS/p-CdTe, 18 19 24 HJs and perovskite layers 26 were investigated. However, except the work, 27 there is a lack of research devoted to the study of such losses in the SCs based on CZTS absorber.…”
