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%.
