Abstract Scope |
Current thin film solar cell technologies suffer from many drawbacks: low earth-abundance in Cu(In,Ga)(Se,S)2 (CIGS) or stability issues in organic-inorganic perovskite halides. My talk will focus first on recent work using high-throughput computational screening to identify new solar absorbers with exceptionally high carrier lifetime due to favorable defects. The second part of my talk will focus on the the eart-abundant CuZnSnS2 (CZTS) absorber. We will show using ab initio computations that Cu-Zn mixing in this material affects significantly lifetime through deep defect stabilization. I will conclude my talk outlining new avenues for future solar absorber research. |
