A Review of CZTS Thin‐Film Solar Cells Using Tandem and Multijunction Structures

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
Copper zinc tin sulfide (CZTS) is an earth‐abundant, nontoxic, and cost‐effective absorber material that has gained significant attention as a sustainable alternative to CIGS and CdTe in thin‐film photovoltaics (PVs). With a direct bandgap of 1.4–1.5 eV and a high absorption coefficient exceeding 104 cm−1, CZTS is well suited for both single‐junction ...

Fabrication of CZTS(Se) thin films by single-target sputtering technique and their relevant application in solar cells [PDF]

open access: yes, 2016
Cu2ZnSnSxSe4-x(CZTSSe)具有合适的禁带宽度(1.5eV)和较高的光吸收系数(α>104cm-1),且元素储量丰富,是最具潜力的高效率、低成本新型绿色光伏材料之一。但是,CZTS材料组分容忍度和单晶区域很小,存在二次相和元素分解等问题,难以制备高质量的CZTS薄膜。目前,CZTS薄膜器件的最高转换效率为12.6%,远低于32%的理论效率。为了发展高效率、低成本的CZTS薄膜技术,大量的研究工作必不可少。 论文的第一部分,采用操作简便的单靶(等化学计量的Cu2ZnSnS4四元化合物靶材 ...

Band Alignment Engineering of Cu‐Based Hole Transport Layers for High‐Efficiency CZTS Thin‐Film Solar Cells: A SCAPS‐1D Simulation Analysis

open access: yesInternational Journal of Photoenergy, Volume 2026, Issue 1, 2026.
The practical efficiency of Cu2ZnSnS4 (CZTS) thin‐film solar cells remains constrained by unfavorable band alignment, high defect densities, and inefficient charge extraction at interfaces. This study numerically investigates and optimizes CZTS‐based solar cells by evaluating four Cu‐based hole transport layers (HTLs)—Cu2O, CuO, CuI, and CuSCN—to ...

Synergistic Passivation of Bulk and Heterojunction Defects via Dual‐Functioned Interlayer Treatment for High‐Efficiency Sb2(S,Se)3 Solar Cells

open access: yesAdvanced Science, Volume 12, Issue 47, December 18, 2025.
This work introduces a dual‐function KI treatment that simultaneously enhances Sb2(S,Se)3 absorber quality and CdS heterojunction properties. Iodide diffusion passivates bulk defects while improving crystallization and modifies the ETL's band alignment. The resulting spike‐like interface suppresses recombination, achieving a 10.06% PCE.
