AbstractThis work deals with the influence of sodium on the properties of CZTSSe material and solar cells. For that purpose, two types of substrates are compared, one with low sodium content (borosilicate glass), the other one with higher sodium content (soda-lime glass). In each case the Na-content in the CZTSSe passing from the substrate through the Mo back contact is quantified by secondary ion mass spectroscopy analysis. Photoluminescence spectroscopy indicates that better quality material is achievable when increasing the Na-content in the CZTSSe. The material characterization results are

Cd is categorized as a toxic material with restricted use in electronics as there are inherent problems of treating waste and convincing consumers that it is properly sealed inside without any threat of precarious leaks. Apart from toxicity, band-gap of CdS is about 2.40–2.50 eV, which results significant photon loss in short-wavelength range which restricts the overall performance of solar cells.

We report an approach to incorporate Ge into Cu2ZnSnSe4 using GeSe vapor during the selenization step of alloyed metallic precursors. The vapor incorporation slowly begins at T ≈ 480 °C and peaks at 530 °C, resulting in a Ge-based composition shift inside the previously formed kesterite layer. We initially observe the formation of a Ge-rich surface layer that merges into a homogeneous distribution of the incorporated element during the further dwelling stage of the annealing. This approach is very versatile and could be used in many similar fabrication processes for incorporating Ge into CZTSe

Abstract:
The development of flexible solar cells utilizing non-toxic, earth-abundant materials is of paramount importance in driving market competitiveness and fostering the adoption of innovative business models such as Building Integrated Photovoltaics. While CZTS-based (Cu2ZnSnS4, Cu2ZnSnSe4, Cu2ZnSn(S,Se)4) solar cells offer promising cost advantages due to their low-cost available absorber materials, their progress has been impeded by challenges like narrow phase stability and secondary phase defects. To address these challenges, researchers have been actively exploring the potential of metal-dopi

Abstract:
Thin-film solar cells (TFSCs) represent a promising frontier in renewable energy technologies due to their potential for cost reduction, material efficiency, and adaptability. This literature review examines the key materials and advancements that make up TFSC technologies, with a focus on Cu(In,Ga)Se2 (CIGS), cadmium telluride (CdTe), and Cu2ZnSnS4 (CZTS) and its sulfo-selenide counterpart Cu2ZnSn(S,Se)4 (CZTSSe). Each material’s unique properties—including tuneable bandgaps, high absorption coefficients, and low-cost scalability—make them viable candidates for a wide range of applications, f

Abstract:
Here we investigated a novel layer-based optimization technique to improve the performance of a CZTSe solar cell. By using this technique, the optical behavior and electrical properties of the proposed solar cell improved significantly as a result of the changes in the layer specifications and the layer materials. The structure of the cell consisted of an absorber laid on a conducting layer and covered by Indium Tin Oxide (ITO), with ZnO on its top surface. Due to the employment of the CSLO technique, a p+pn junction was formed between the absorber and window layers, which provided a lower rec

Abstract:
In this paper, we designed a two-junction (tandem) solar cell model (tandem solar cell), consisting of an top and bottom subcell with absorber layers of Cu2SnZnS4 (CZTS) and Cu2SnZnSe4 (CZTSe) materials, respectively, for each subcell with a ZnS buffer layer and a ZnO window layer. This model was validated using the SCAPS-1D numerical simulation program. We also optimized the performance of the tandem cell as a whole using the simulation by studying the effect of the thickness of the absorber layer of the top subcell and the thickness of the absorber layer of the bottom subcell and its doping.

ABSTRACTWe fabricated Cu2ZnSn(SxSe1-x)4 (CZTSSe) solar cells by a printing and high-pressure sintering (PHS) process. First, the CZTSSe solid solution powders were synthesized by heating the elemental mixtures at 550oC for 5 h in an N2 gas atmosphere. We fabricated CZTSSe films by a printing and high-pressure sintering (PHS) process. The obtained dense CZTSSe film was post-annealed at 550oC for 10 min under an N2 +5% H2S gas atmosphere. We fabricated CZTSSe solar cells with the device structure of Ag/ITO/i-ZnO/CdS/CZTSSe/Mo/soda-lime glass. The CZTSSe solar cell showed an efficiency of 2.1%, w
