The selenization annealing process is vital for highly efficient kesterite solar cells. Generally,
SnS is added during the selenization process, but excessive S and related defects are …

Abstract Kesterite Cu 2 ZnSnS 4 (CZTS), Cu 2 ZnSnSe 4 (CZTSe), and its alloys Cu 2 ZnSn
(S x, Se 1− x) 4 (CZTSSe, 0< x< 1), are cost-effective thin-film photovoltaic materials to meet …

Alkali metal doping, typically Li+ doping, is beneficial for CZTSSe solar cells. Herein, aiming
at the low solubility of conventional LiF which is hard to directly introduce into the precursor …

Critical review on the controllable growth and post-annealing on the heterojunction of the
kesterite solar cells Page 1 ACCEPTED MANUSCRIPT • OPEN ACCESS Critical review on …

For high efficiency kesterite Cu 2 ZnSn (S, Se) 4 (CZTSSe) solar cell, CdS thin film was
usually used as a buffer layer. However, due to the toxicity of Cd and pollution problems …

Kesterite Cu2ZnSnSe4 (CZTSe), Cu2ZnSn (S, Se) 4 (CZTSSe), and Cu2ZnSnS4 (CZTS)
solar cells show considerably lower open-circuit voltages than their theoretical values. The …

Abstract Cu2ZnSn (S, Se) 4 (CZTSSe) solar cells, composed of earth‐abundant materials,
face challenges in achieving high power conversion efficiency (PCE) due to non‐radiative …

It is widely known that the challenge of making good electrical contact at the back electrode
interface will always follow us for high-efficient kesterite-type CZTSSe thin-film solar cells …

Rationally controlling the electronic property of the absorbers is effective but challenging in
overcoming the drawbacks of large open-circuit voltage (V OC) deficit for high efficient Cu 2 …

Due to their inherent nature, kesterite solar cells exhibit complex secondary phases and
intrinsic lattice defects. As a result, the power conversion efficiencies (PCEs) of kesterites are …
