Giant oscillator strength in the band-edge light absorption of zincblende, chalcopyrite and kesterite solar cell materials
Masato Kato, Mitsutoshi Nishiwaki, Hiroyuki Fujiwara
In semiconducting solar-cell absorbers, high absorption coefficient (alpha) near the band-edge region is critical to maximize the photocurrent generation and collection. Neverthele…

Tail state formation in solar cell materials: First principles analyses of zincblende, chalcopyrite, kesterite and hybrid perovskite crystals
Mitsutoshi Nishiwaki, Keisuke Nagaya, Masato Kato +6
Tail state formation in solar cell absorbers leads to a detrimental effect on solar cell performance. Nevertheless, the characterization of the band tailing in experimental semicon…
