Fabrication of 7.2% Efficient CZTSSe Solar Cells Using CZTS Nanocrystals

Journal of the American Chemical Society, 2010
Earth abundant copper-zinc-tin-chalcogenide (CZTSSe) is an important class of material for the development of low cost and sustainable thin film solar cells. The fabrication of CZTSSe solar cells by selenization of CZTS nanocrystals is presented. By tuning the composition of the CZTS nanocrystals and developing a robust film coating method, a total ...

The effect of Rb doping on CZTSSe solar cells

Solar Energy, 2019
Abstract Alkali metal doping is a promising method to enhance the performance of Cu2ZnSn(Se,S)4 (CZTSSe) solar cells due to its excellent effect on Cu(In,Ga)Se2 (CIGS) solar cells. In this work, rubidium (Rb) was doped in CZTSSe absorbers by sputtering Rb doped Cu2ZnSnS4 (CZTS) target with subsequent H2Se contained annealing.

Suppressing Element Inhomogeneity Enables 14.9% Efficiency CZTSSe Solar Cells

Advanced Materials
AbstractKesterites, Cu2ZnSn(SxSe1−x)4 (CZTSSe), solar cells suffer from severe open‐circuit voltage (VOC) loss due to the numerous secondary phases and defects. The prevailing notion attributes this issue to Sn‐loss during the selenization. However, this work unveils that, instead of Sn‐loss, elemental inhomogeneity caused by Cu‐directional diffusion ...

Trap density simulations on CZTSSe solar cells with AMPS-1D

Journal of Materials Science: Materials in Electronics, 2018
This work involves the simulation of Cu2ZnSn(S,Se) (CZTSSe) solar cell in analysis of microelectronic and photonic structures (AMPS-1D) while taking into account previous experimental and theoretical data on CZTS, CZTSe, CZTSSe, CdS and ZnO based devices. We start from the results of the champion CZTSSe solar cell with an efficiency of 12.6%.

Enhancing the performance of CZTSSe solar cells with Ge alloying

Solar Energy Materials and Solar Cells, 2012
Abstract The ability to alloy Cu2ZnSn(S,Se)4 with Ge provides a unique ability to band-gap engineer the absorber film by controlling the relative cation ratios. In here, a preliminary study on adjusting the Ge to Sn ratio is shown to significantly improve the device performance of CZTSSe thin film solar cells.
