Potassium processing interface engineering for carrier regulation of efficient CZTSe solar cells
Moqing Wu, YingZi Liu, Naihan Han, Yue Chen et autres
Alkali metal treatment can improve the crystal quality of CZTSe solar cell absorber layers, promote crystal growth, and effect carrier concentration. In this work, the absorber layers were prepared with different concentrations of KF solution through a simple soft chemical treatment method. …
