Kesterite Cu2ZnSn(SxSe1−x)4 has tunable band-gap values in the range 1 to 1.5 eV depending upon Sulphur/Selenium stoichiometry. We analyze proposed tandem configuration of kesterite absorber family using SCAPS-1D for device performance. Pure sulphide Cu2ZnSnS4 (CZTS) bandgap is utilized as top cell and a sulpho-selenide (CZTSSe) 1.1 bottom stacked configuration. utilize script file capability S...

Effectively incorporating alkali metals or alternative isovalent cations into Cu2ZnSnS4 (CZTS) is considered one of the most promising strategies for realizing a step-change improvement in photovoltaic device performance. Herein, we successfully manipulate local distribution Na and Cd by moisture-assisted post-deposition annealing (MAPDA) treatment combined with subsequent heterojunction heat t...

Relatively fast achievements in the kesterite solar cell technology have been made over last decade, but experimental efficiency is still ?13%. One proposed reason an inappropriate band alignment with Cu2ZnSnS4 (CZTS) and CdS that results strong interface recombination losses. Results of this work show temperature duration air annealing CZTS/CdS heterojunction are essential for device performan...

Thin-film solar cells are simple and affordable to produce, but their efficiency is low compared crystalline-silicon cells, needs be improved. This study investigates the photovoltaic performance of different absorber materials (CdTe, CIGS, Sb2Se3, CZTS) with structure Au/absorber/CdS/ITO. The research uses SCAPS (Solar Cell Capacitance Simulator), a mathematical model based on Poisson continui...

This paper aims to study the properties of absorber layer and heterojunction in kesterite solar cells. The Cu2ZnSnS4 (CZTS) thin films were layered on a glass substrate from colloidal solution metal salts thiourea dissolved mixture water ethanol deposited by spin coating technique. samples then heat treated furnace, presence sulphur powder under nitrogen gas flow. results revealed formation hom...

Successful implementation of molecular solution processing from a homogeneous and stable precursor would provide an alternative, robust approach to process multinary compounds compared with physical vapor deposition. Targeting deposition of chemically clear, high quality crystalline films requires specific molecular structure design and solvent selection. Hydrazine (N2H4) serves as a unique and...

Abstract The use of graphite substrates has been demonstrated in thin-film Cu 2 ZnSnS 4 (CZTS) solar cells and can serve as alternative electrodes for next-generation, cells. From the early stages CZTS development, Mo-coated composed copper (Cu), zinc (Zn), tin (Sn), sulfur (S) have employed stability at high temperature. However, Mo become a rare metal recent years; correspondingly, there are ...

Cu2ZnSnS4 (CZTS) thin films in 61 nm, 112 242 nm and 313 thickness which have been produced by Pulsed Laser Deposition (PLD) on Soda Lime Glass substrates as a function of the number laser pulses. As deposition ablated material has augmented with increasing pulses, it noticed that CZTS-ultrathin film’s thicknesses particle sizes increased, their crystalline structures improved. Larger particles...

Abstract The power conversion efficiency of Cu 2 ZnSnS 4 (CZTS) solar cells is still limited by deep defects, low minority carrier lifetime and high recombination rates at the CZTS/CdS interface. objective this study was to find an effective method reduce interface CZTS monograin layer cells. A two-step heterojunction formation process applied controlling intermixing Cd in interface, which resu...

Abstract Cu 2 ZnSnS 4 (CZTS) thin film solar cells (TFSCs) have received great attention from the cell industry for their environment, price, high absorption coefficient and electronic properties. This work provides a strategy to prompt photoelectric conversion efficiency (η) of CdS/CZTS-based TFSCs via introducing back surface field (BSF) layer wxAMPS simulate results.
