Impact of Lithium as Interfacial Treatment for CZTSSe Solar Cells

2024 IEEE 52nd Photovoltaic Specialist Conference (PVSC)
Cu2ZnSn(S,Se)4 (CZTSSe), despite its slow progress in terms of efficiency, stands out as a viable option for solar cell absorber materials due to its comparatively low-cost fabrication process, and abundance of constituent elements. The efficiency of CZTSSe faces challenges, particularly a notable Voc deficit arising from its non-stoichiometric nature ...

Study of CZTS and CZTSSe solar cells for buffer layers selection

Applied Surface Science, 2017
Abstract The output characteristics, of a thin film solar cell, are affected by several parameters related to the hetero-structure that is taken into account. In this paper, nontoxic thin film solar cells were studied. CdS/CZTS, CdS/CZTSSe, ZnS/CZTS and ZnS/CZTSSe hetero-junctions were numerically simulated using the Solar Cell Capacitance Simulator (

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 ...

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.

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.
