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

open access: yesJPhys 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 ...

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 ...

Potential fluctuations on CZTSSe solar cells admittance

open access: yes, 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

Over 12% efficient kesterite solar cell via back interface engineering

open access: yes, 2022
International audienceKesterite Cu2ZnSn(S,Se)4 (CZTSSe) has attracted considerable attention as a non-toxic and earth-abundant solar cell material. During selenization of CZTSSe film at high temperature, the reaction between CZTSSe and Mo is one of the ...

Modelling and Analysis of CdS/CZTSSe Based Thin Film Solar Cell

open access: yes, 2018
Solar cells with a High efficiency and desire characteristics are modelled by considering the characteristics of the materials. An earth-abundant material Cu2ZnSn2(S, Se)4 (CZTSSe) could be a wise choice for the solar cell material with a band gap of 1 ...

Flexible high-efficiency CZTSSe solar cells on stainless steel substrates

open access: yes, 2019
Stainless steel (SS) foil is made of abundant materials and is a durable and flexible substrate, but the efficiency of a solar cell on SS foil deteriorates via the diffusion of impurities from the SS substrate into a Cu2ZnSn(S,Se)4 (CZTSSe) absorber ...

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

open access: yesJPhys 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

open access: yesCarbon 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.
