Low-cost p-type dye-sensitized solar cells based on Dawson-type transition metal-substituted polyoxometalate inorganic co-sensitizers

Abstract

Photosensitizers play a crucial role in p-type dye-sensitized solar cells (p-DSSCs). In this study, we first introduced two Dawson-type transition metal-substituted polyoxometalate dyes to co-sensitize the NiO electrode and achieved an overall power conversion efficiency (PCE) of 0.0464%, which is the highest value reported for inorganic photosensitizers in p-DSSCs.
