Structural, Electronic, and Optical Properties of Cu2sns3 Solar Absorber: A First-Principle Density Functional Theory Investigation. Abstract The development of inexpensive, non-toxic, high efficiency and earth-abundant solar absorbers is critical for terawatt scale implementation of photovoltaics. Cu2SnS3 is a promising earth abundant absorber material that is attracting attention recently for optoelectronic application including photovoltaic solar cells. […]
