Zhang, Yaohong; Wu, Guohua; Mora-Sero, Ivan; Ding, Chao; Liu, Feng; Huang, Qingxun; Ogomi, Yuhei; Hayase, Shuzi; toyoda, taro; Wang, Ruixiang; Otsuki, Joe; Qing, Shen American Chemical Society (2017-04)A novel organic small molecule bis-triphenylamine with spiro(fluorene-9,9′-xanthene) as the conjugated system, named BTPA-4, is successfully synthesized and employed as the hole-selective layer (HSL) in colloidal quantum ... -
Mechanisms of charge accumulation in the dark operation of perovskite solar cells
Ripolles, Teresa S.; Baranwal, Ajay K.; Nishinaka, Koji; Ogomi, Yuhei; Garcia-Belmonte, Germà; Hayase, Shuzi Royal Society of Chemistry (2016)In this work, a new current peak at forward bias in the dark current–voltage curves has been identified for standard mesoscopic perovskite solar cells. This characteristic peak appears only under some specific conditions, ... -
