Highly Efficient Inverted Organic Solar Cells Through Material and Interfacial Engineering of Indacenodithieno[3,2‐b]thiophene‐Based Polymers and Devices
Jeremy J. Intemann,Kai Yao,Kai Yao,Yongxi Li,Hin-Lap Yip,Yun-Xiang Xu,Po-Wei Liang,Chu-Chen Chueh,Feizhi Ding,Xi Yang,Xiaosong Li,Yiwang Chen,Alex K.-Y. Jen +12 more
TL;DR: In this article, a synergistic approach combining new material design and interfacial engineering of devices is adopted to produce high efficiency inverted solar cells by incorporating either an alkyl thiophene (PIDTT-DFBT-T) or alkyal thieno[3,2-b]thiophene π-bridge as spacer.
Journal ArticleDOI
Improved efficiency and stability of Pb–Sn binary perovskite solar cells by Cs substitution
Xiao Liu,Xiao Liu,Zhibin Yang,Chu-Chen Chueh,Adharsh Rajagopal,Spencer T. Williams,Ye Sun,Alex K.-Y. Jen +7 more
TL;DR: Partially replacing Pb with Sn in organic-inorganic lead halide perovskites has been proven as a promising approach to reduce environmental toxicity and develop low bandgap (as low as 120 eV) PVSCs.
