Abstract:
Kesterite, a quaternary compound of Cu2ZnSnS4, is a promising option as a material absorber to reduce the cost of photovoltaic solar cells. The solvothermal method is a way to synthesize nanoparticles of this material. In this work, once synthesized, particles were deposited on a substrate through evaporation, and their morphological, structural, and optical properties were studied. Results show that changes of precursor ratios during solvothermal synthesis result in a modification of particle morphology but not on its size. The deposition of already synthesized kesterite through evaporation p

Abstract:
The kesterite, Cu2ZnSnS4has a big potential as a future solar material in replacing current material. Although the kesterite and copper indium gallium selenide, CIGS has almost same structure but the constituent elements of kesterite are earth-abundance, cheaper and non-toxic. The chalcogen elements existed inside the kesterite compound are selenium and sulphur, Cu2ZnSnSe4/ Cu2ZnSnS4. Therefore, the structural flexibility of kesterite opens up an avenue to develop light-absorber material with suitable properties and applications. The density functional theory (DFT) has been used to calculate t

Abstract:
To find the optical properties of Cu2ZnSnS4 (CZTS) absorber in two crystal structures (kesterite and stannite) which are key factors determining solar cell performance and are based on the electronic structures, a systematical calculation of electronic and optical properties were calculated using density functional theory. The results suggested that the optical properties of CZTS had a rather weak dependence on the (Cu, Zn) cation ordering. Kesterite and stannite CZTS both suited for photovoltaics with large light absorption coefficient ( &gt; 104 cm-1 ) in the visible light region that is the

Abstract:
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

While cadmium telluride and copper–indium–gallium–sulfide–selenide (CIGSSe) solar cells have either already surpassed (for CdTe) or reached (for CIGSSe) the 1 GW yr −1 production level, highlighting the promise of these rapidly growing thin-film technologies, reliance on the heavy metal cadmium and scarce elements indium and tellurium has prompted concern about scalability towards the terawatt level.

In this work, thin-film solar cells with a kesterite-type Cu<sub>2</sub>ZnGeS<sub>x</sub>Se<sub>4-x</sub> (CZGSSe) absorber were prepared from four different metal salt solutions.

The structural and morphological properties of the absorbers are compared with an additional focus on the electrical properties of the resulting thin-film solar cells.

Abstract:
Cu2ZnSnS4 (CZTS) is a promising absorber material for thin-film solar cells since it contains no rare or toxic elements, has a high absorption coefficient and a near ideal bandgap energy. It does, however, present some challenges due to the limited single-phase region of the desired kesterite phase and its instability towards decomposition. Sputtering of CZTS from quaternary, compound targets using RF magnetron sputtering is known.
