Quantum Devices｜Integration Synthesis of Graphene Nanoribbon Quantum Dot Devices
We are dedicated to developing transparent solar cells by maximizing the unique feature of TMDs, which are semiconductors at the atomic level. Initially, we focused on Schottky-type solar cells, which are easy to scale up. We conducted a demonstration of TMD Schottky solar cells, optimizing the electrode materials on both ends of the TMD.
Through device design that separates functions, with one side facilitating charge separation with a high Schottky barrier and the other side serving as a low Schottky barrier for current collection, we achieved the highest overall power generation efficiency (0.7%) for TMD solar cells with a few layers or less.
