有機ペロブスカイト太陽電池の低温作製技術開発

Abstract

Organic perovskite solar cells (OPSC) have some atractive advantages as high power conversion efficiency (PCE)，solution processability and son on. However，if a plastic substrate is considered for reducing the cost and light-weight of cells，the lower temperature fabrication process must be developed. In this study， we discussed the low temperature sintering process for a conventional OPSC and the fabrication process for an inverted OPSC. Although the OPSC with a high PCE was not successful in the former method， the OPSC with ～7 % PCE could be fabricated in the latter method.
