Modeling of optical losses in graphene contacted thin film solar cells

Tunable Mid-Infrared Graphene Plasmonic Cross-Shaped Resonator for Demultiplexing Application

“…In practice, graphene has strong confinement of lightwaves, long propagation length, and low loss making it superior to metals [21][22][23]. Because of the significant advantages of graphene, many graphene based structures-such as filters [24,25], demultiplexers [26,27], modulators [28,29], couplers [30,31], absorbers [32,33], and solar cells [34]-are designed and analyzed. Fabrication of graphene-based devices in MIR region was recently reported in [35,36].…”

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.…”

Optical loss analysis of Sb2S3 and Sb2Se3 thin film solar cells: A Quantitative Assessment

“…Therefore, measurements taken on glass/ITO and glass/ITO/CdS architectures can yield significantly different outcomes compared to the real structure due to notable variations in refractive indices and extinction coefficients between air and the semiconducting substrate materials including ITO or window partner layer (CdS). Additionally, transmission curves observed in the literature often exhibit prominent interference oscillations that are slightly higher than those found in the actual device architecture [18][19][20]. To the best of our knowledge, studies on optical losses in CdS/Sb 2 S 3 and CdS/Sb 2 Se 3 solar cells based on optical constants of the layers used, following optical modeling and quantitative assessment are rarely found in the literature.…”
