Journal ArticleDOI
Theoretical analysis of the effect of conduction band offset of window/CIS layers on performance of CIS solar cells using device simulation
Takashi Minemoto,Takuya Matsui,Hideyuki Takakura,Yoshihiro Hamakawa,Takayuki Negami,Yasuhiro Hashimoto,Takeshi Uenoyama,Masatoshi Kitagawa +7 more
TL;DR: In this paper, the effect of conduction band offset of window/CIGS layers on performance of CIGS solar cells was investigated and it was shown that good performance can be obtained when the conduction bands of window layer positions higher by 0.4 to 0.5 eV than that of CIC.
Journal ArticleDOI
Photocatalytic generation of hydrogen by core-shell WO3/BiVO4 nanorods with ultimate water splitting efficiency
Yuriy Pihosh,Ivan Turkevych,Kazuma Mawatari,Jin Uemura,Yutaka Kazoe,Sonya Kosar,Kikuo Makita,Takeyoshi Sugaya,Takuya Matsui,Daisuke Fujita,Masahiro Tosa,Michio Kondo,Takehiko Kitamori +12 more
TL;DR: It is shown that the effectiveness of each process can be separately maximized in a nanostructured heterojunction with extremely thin absorber layer on WO3/BiVO4+CoPi core-shell nanostructureured photoanode that achieves near theoretical water splitting efficiency.
Journal ArticleDOI
Triple-junction thin-film silicon solar cell fabricated on periodically textured substrate with a stabilized efficiency of 13.6%
Hitoshi Sai,Takuya Matsui,Takashi Koida,Koji Matsubara,Michio Kondo,Shuichiro Sugiyama,Hirotaka Katayama,Yoshiaki Takeuchi,Isao Yoshida +8 more
TL;DR: In this article, a triple-junction thin-film silicon solar cell fabricated on a periodically textured substrate with a high-mobility front transparent contacting layer was reported, achieving a stabilized efficiency of 13.6% and a notably high short-circuit current density of 32.9 mA/cm2.
Journal ArticleDOI
High-rate deposition of microcrystalline silicon p-i-n solar cells in the high pressure depletion regime
TL;DR: In this paper, the presence of hydrogenated crystalline grain boundaries can be detected via the crystalline surface hydrides contribution to the narrow high stretching modes by infrared transmission spectroscopy.
Journal ArticleDOI
High-efficiency amorphous silicon solar cells: Impact of deposition rate on metastability
Takuya Matsui,Adrien Bidiville,Keigou Maejima,Hitoshi Sai,Takashi Koida,Takashi Suezaki,Mitsuhiro Matsumoto,Kimihiko Saito,Isao Yoshida,Michio Kondo +9 more
TL;DR: The impact of varying deposition rates on the light-soaking stability of p-i-n solar cells has been investigated in this article, showing that the metastable effect persists in a-Si:H regardless of the deposition rate.
