Organo-lead halide perovskite solar cells (PSCs) have attracted the attention due to the high efficiency and the cost-effective manufacturing by printing system. However, PSCs have been unstable due to water from outside and iodide (I-) reacts with the back contact metal (Au or Ag) inside. To solve these two issues, porous-carbon-electrodes have been introduced in PSCs by a group of Hongwei Han. The MPLE-PSCs show very high stability: thermal stability at 100 ֩C over 4500 h in dark (by Univ. of Hyogo, Japan); damp-heat stability at 85 ֩C-85%RH over 3,000 h in dark (by Univ. of Hyogo and Kishu Giken Kogyo, Japan); light stability at 55 ֩C over 10,000 h (by EPFL, Switzerland). In this conference, we will show a challenging work of high thermal stability at 130 ֩C, which is required for outer space application.
