Abstract

Although the Bi2 S3 QDs have an ideal bandgap for the efficient light absorbers, the Bi2 S3 QDs sensitised solar cells generally indicate low photovoltaic properties owing to the active photocorrosion of Bi2 S3 QDs. Herein, we report the enhancement of Bi2 S3 QDs sensitised solar cells using the co-sensitisation of Bi2 S3 with CdS QDs. By the homogeneous covering as well as effective blocking of photocorrosion and recombination, the CdS/Bi2 S3 co-sensitised solar cells showed three-fold increase in efficiency.
