Additive-Free Transparent Triarylamine-Based Polymeric Hole-Transport Materials for Stable Perovskite Solar Cells
The Inside Back Cover picture shows a perovskite solar cell in a multilayer architecture containing a fluorine-doped tin oxide substrate, mesoporous TiO2 and triple-cation perovskite active layer, new dopant/additive-free triarylamine polymeric hole-transport material, and gold electrode. Despite the absence of dopants/additives, the use of this new hole-transport material (pink layer) yields highly efficient perovskite solar cells enabling stable devices even at elevated temperatures (85°C). More details can be found in the Communication by Matsui et al. on page 2567 in Issue 18, 2016
