German scientists have developed a new process for the formation of a phase pure kesterite Cu2ZnSnSe4 (CZTSe), which they claim can improve the material homogeneity and suppress the well-known issue of tin losses. The new technique is based on stacked elemental and alloyed precursors and a Zn/Cu-Sn/Zn precursor structure.Scientists from Germany's Carl von Ossietzky University of Oldenburg have created a new process for the formation of a phase pure kesterite Cu2ZnSnSe4 (CZTSe), to facilitate the development of a solar cell with an efficiency of more than 10%. The researchers describe the process ...Den vollständigen Artikel lesen ...
