Using Cu–Zn–Sn–O Precursor to Optimize CZTSSe Thin Films Fabricated by Se Doping With CZTS Thin Films

Frontiers in Chemistry, 2021
The copper–zinc–tin oxide (CZTO) precursor was synthesized to avoid sudden volume expansion from CZTO precursor to Cu2ZnSnS4 (CZTS) thin films and smooth CZTSSe thin-film surfaces without pinholes.

Numerical simulation of SnS/CZTSSe heterojunction solar cells

Journal of Ovonic Research, 2023
This work combines the advantages of SnS and CZTSSe to constitute the SnS/CZTSSe heterojunction solar cells, and the effects of various factors on cell performance were studied by using numerical simulation. The results show that the optimal thickness of CZTSSe and SnS are 0.1 μm and 2.0 μm, respectively.

Performance improvement of Cu2ZnSn(S,Se)4 thin-film solar cells by optimizing the selenization temperature

AIP Advances, 2021
In this work, Cu2ZnSnS4 (CZTS) precursor films were deposited using a water-based solution approach. Subsequently, selenization was performed at different temperatures in the range of 480–610 °C to prepare Cu2ZnSn(S,Se)4 (CZTSSe) absorber-layer films ...

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 ...

Impact of Sb and Na Doping on the Surface Electronic Landscape of Cu2ZnSnS4 Thin Films [PDF]

, 2018
Open-circuit voltage deficiency is the key limiting factor in Cu2ZnSnS4 (CZTS) thin-film solar cells, which is commonly associated with band tails and deep gap states arising from elemental disorder.
