This project aims to develop efficient and durable PEC devices using low cost semiconducting materials. Specifically, our program aims to modify the optoelectronic properties of the PV-grade copper chalcopyrite material class for PEC water splitting. Alongside, we are engineering new surface treatments to improve chalcopyrites’ surface energetics, their catalysis toward HER as well as their resistance against photo-corrosion. The status of the UH’s technical targets is documented in Table 1.
