Control of CIGS roughness by initial selenization temperature

Autor: Marsha L. Langhorst, Melissa Mushrush, Rebekah K. Feist, Ankur Khare, Art Wall, Steve Rozeveld, John J. Kim, Eugene Bykov, Qiongzhong Jiang

Publikováno v: 2015 IEEE 42nd Photovoltaic Specialist Conference (PVSC).

When formed by coevaporation, copper indium gallium diselenide (CIGS) films are typically more smooth than those formed by a two-step, precursor-selenization process. While some amount of roughness is desirable for minimizing reflection, extreme roug

Publikováno v: 2012 38th IEEE Photovoltaic Specialists Conference.

A new sputtered process for cadmium sulfide (CdS) has been developed that boosted efficiency of a PV device baseline (with single-stage, coevaporated CIGS) by ∼ 2.7% (absolute) to an average of ∼10%. The process is highly scalable to a roll-to-ro
