Sputtered seed-assisted growth of CuS nanosheet arrays as effective counter electrodes for quantum dot-sensitized solar cells

摘要

CuS nanosheet arrays (NSAs) obtained by combining a physical radio frequency (RF) sputtered CuS seeding process with a facile and green hydrothermal post-treatment, are employed as counter electrodes (CEs) for quantum dot-sensitized solar cells (QDSSCs). Such CuS NSAs show superior electrocatalytic ability as compared to the conventional Pt CEs and other three types of CuS nanosheet films prepared via different methods. (C) 2017 Elsevier B.V.
