DFT Modeling and Impedance Spectroscopy Analysis of a High Performance Zirconia‐Based Solar Cell

Nano Select, Volume 7, Issue 3, March 2026.
p‐SnS/n‐CdS heterojunction solar cells with Al‐ZnO/i‐ZnO window layers simulated using SCAPS‐1D and impedance spectroscopy enabled tracking of solar cell parameters. The optimal performance (η = 22.76%, Voc = 0.77 V) was achieved with a 5 µm SnS absorber at Rs = 1Ω.cm−2 and Rsh = 10 kΩ.cm−2.

CdCl2 Treatment for Cu2ZnSn(S,Se)4: A Method to Enhance the Solar Cell Performance

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 3, Page 271-285, March 2026.
We present, for the first time, two alternative CdCl2 treatments applied to solution‐processed kesterite (CZTSSe) absorbers: pre‐selenization and post‐selenization. Carrier concentration is consistently increased by either route, whereas the band gap decreases with pre‐selenization but remains nearly constant with post‐selenization; enhanced defect ...

Towards highly efficient thin-film solar cells with a graded-bandgap CZ TSSe layer. Part II: Piecewise-homogeneous bandgap grading

JPhys Energy
In Part I, we optoelectronically optimized a thin-film solar cell with a graded-bandgap CZTSSe photon-absorbing layer and a periodically corrugated backreflector, using the hybridizable discontinuous Galerkin (HDG) scheme to solve the drift-diffusion ...

Numerical Analysis of AgInSe2‐Based Thin‐Film Solar Cells Towards High Efficiency

Nano Select, Volume 7, Issue 2, February 2026.
In this work, SCAPS‐1D is used to numerically explore AgInSe2‐based thin‐film solar cells. Using CuS, WSe2, and AlSb as back surface field (BSF) layers with a CdS window improves carrier separation and built‐in potential. AgInSe2's promise for high‐performance, stable, and environmentally friendly solar applications is demonstrated by the optimised CdS/

Potential fluctuations on CZTSSe solar cells admittance

, 2016
The Cu2ZnSn(SxSe1-x)4 (CZTSSe) kesterite compounds have proven their interest for next more friendly environment thin film solar cell technologies, compared to CuInxGa1-x(SSe)2 (CIGS) devices, currently in production, as they are composed of earth-abundant and non-toxic elements. However, an open-circuit voltage lower than expected is commonly reported

Zn1−xMg xO thin films as a sustainable layer for CZTSSe solar cells

JPhys Energy
Traditionally, CdS serves as the buffer layer in Cu _2 ZnSn(S,Se) _4 (CZTSSe) solar cells, but poses issues such as toxicity, optical losses, and a suboptimal conduction band offset (CBO). This study explores the use of Zn _1− _x Mg _x O (ZMO, 0 ⩽ x ⩽ 1)

Vertical plane depth‐resolved surface potential and carrier separation characteristics in flexible CZTSSe solar cells with over 12% efficiency

Carbon Energy
Cu2ZnSn(S,Se)4 (CZTSSe) solar cells have resource distribution and economic advantages. The main cause of their low efficiency is carrier loss resulting from recombination of photo‐generated electron and hole.
