Doping and alloying of kesterites

Journal of Physics: Energy, 2019
Abstract Attempts to improve the efficiency of kesterite solar cells by changing the intrinsic stoichiometry have not helped to boost the device efficiency beyond the current record of 12.6%. In this light, the addition of extrinsic elements to the Cu2ZnSn(S,Se)4 matrix in various quantities has emerged as a popular topic aiming to ...

High Recovery of Selenium from Kesterite‐Based Photovoltaic Cells [PDF]

European Journal of Inorganic Chemistry, 2020
The use of photovoltaic cells is constantly increasing and, in particular, a new generation of thin‐film photovoltaic (PV) cells is under development. The absorber of these new cells, kesterite (CZT(S)Se), is composed of abundant chemical elements. Nonetheless, the development of the recycling process for these elements is indispensable for circular ...
