Electrodes: High‐Performance Solution‐Processed Double‐Walled Carbon Nanotube Transparent Electrode for Perovskite Solar Cells (Adv. Energy Mater. 27/2019)

Abstract

Double‐walled carbon nanotubes are between single‐walled carbon nanotubes and multi‐walled carbon nanotubes. They are comparable to single‐walled carbon nanotubes with respect to the light optical density, but their mechanical stability and solubility are higher. In article number 1901204, Mansoo Choi, Shigeo Maruyama, Yutaka Matsuo, and co‐workers demonstrate a solution‐processed double‐walled carbon nanotube transparent electrode in perovskite solar cells exhibiting an operating power conversion efficiency of 17.2%.
