Organic Photovoltaics: A Cost‐Effective, Aqueous‐Solution‐Processed Cathode Interlayer Based on Organosilica Nanodots for Highly Efficient and Stable Organic Solar Cells (Adv. Mater. 38/2020)

The performance and industrial viability of organic photovoltaics are strongly influenced by the functionality and stability of the interface layers. In article number 2002973, Na Li, Ning Li, Xinghua Wang, Li Nian, and co-workers present an advanced aqueous solution-processed cathode interface layer based on cost-effective organosilica nanodots (OSiNDs). Devices based on the OSiNDs interlayer show improved efficiency and highly enhanced operational stability compared to devices based on the commonly used ZnO interlayer.
