[OWPT7-05] Evaluation of properties of CsPb(Br_1-xCl_x)₃ films as light absorbing layer in photovoltaic power converter for blue light source

*Atsuto Watanabe¹, Shinsuke Miyajima¹ (1. Tokyo Institute of Technology)

We successfully deposited a CsPb(Br_1-xCl_x)₃ film with a bandgap of 2.7 eV for blue-light (455 nm) photovoltaic power converter. The Cl/(Br+Cl) ratio of the film was found to be about 55%.
