Professor Mansoo CHOI’s research team (Department of Mechanical and Aerospace Engineering) has developed a highly efficient transparent conductive oxide (TCO)-free inverted perovskite (CH3NH3PbI3) solar cell by using a graphene transparent electrode. Careful engineering of the interface between the graphene electrode and the hole transport layer enables the highest energy conversion efficiency of 17.1% among TCO-free solar cells to be obtained. “As graphene is flexible, this development will provide the basis for curved solar cells or flexible solar cells in the future,” said Professor Choi. Their results were published in Advanced Energy Materials on February 4 under the title “Solar Cells: Transparent Conductive Oxide-Free Graphene-Based Perovskite Solar Cells with over 17% Efficiency.”
