Optoelectronically optimized colored thin-film CZTSSe solar cells [PDF]

International Workshop on Thin Films for Electronics, Electro-Optics, Energy, and Sensors 2019, 2019
Rooftop solar cells may become more acceptable if they are colored, e.g., red or bluish green, which requires that a certain part of the incoming solar spectrum be reflected. We implemented and optimized an optoelectronic model for Cu2ZnSn(SξSe1-ξ)4 (CZTSSe) solar cells containing (i) a conventional 2200-nm-thick CZTSSe layer with homogeneous bandgap ...

Insight into the Impact of Wide Bandgap Transparent Conducting Oxide on the Performance of Thin Film Solar Cells

Small, EarlyView.
Mg‐ and Ga‐codoped ZnO has emerged as an effective wide‐bandgap transparent conducting oxide for kesterite thin‐film solar cells, combining high transmittance with favorable electrical properties. By enabling near‐flat band alignment, reduced defect‐assisted recombination, and improved electron transport, Mg‐ and Ga‐codoped ZnO enhances the ...

A Comparative Numerical Modeling of High‐Efficient CBTS Solar Cell Using SCAPS‐1D

Nano Select, Volume 7, Issue 6, June 2026.
The highest efficiency achieved is 18.42%, 21.51%, and 21.6% for optimized CBTS/CdS/FTO, CBTS/SnS2/FTO, and CBTS/Cd0.1Zn0.9S/FTO solar cell, respectively. The results prove that low‐toxic Cd0.1Zn0.9S buffer layer provides best performance among all three buffer layers and SnS2 buffer layer also shows promising results.

Revealing the Role of Potassium Treatment in CZTSSe Thin Film Solar Cells [PDF]

Chemistry of Materials, 2017
Potassium (K) post-treatment on CIGSSe has been shown to yield the highest efficiency reported to date. However, very little is known on the effect of K doping in CZTSSe and the mechanism behind the efficiency improvement. Here we reveal the mechanism by which K enhances the charge separation in CZTSSe.
