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 ...

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.

Synthesis and characterization of CZTSSe nanoparticle inks for photovoltaic devices

physica status solidi c, 2015
AbstractCu2ZnSnSe4 (CZTSe) is one of the promising materials as absorber layers in thin film solar cells. It contains earth abundant and non‐toxic elements. With a broad optical band gap at 1.5 eV as well as a high absorbance coefficient of 10–4 cm–1, CZTS is also a good light harvesting material.

Analysis of current conduction mechanism in CZTSSe/n-Si structure

Journal of Materials Science: Materials in Electronics, 2018
In this study, Cu2ZnSn(S,Se)4 (CZTSSe) thin films were deposited by the single step thermal evaporation process using the sintered powder of CZTSSe on soda lime glass (SLG) and Si wafer substrates. The structural, optical, and electrical properties of deposited films were investigated.
