Carrier recombination and transport for Sb2Se3-based homojunction thin film solar cells

Résumé

Antimony selenide (Sb2Se3) exhibits huge potential as an absorber for photovoltaic applications due to its narrow bandgap and high-absorption coefficient at visible wavelength. Herein, Sb2Se3-based homojunction thin film solar cells with a configuration of Glass/FTO/Cu-Sb2Se3/I-Sb2Se3/Al were fabricated via radio frequency magnetron sputtering. By analyzing the carrier recombination and transport, especially at the interface, it was found that large recombination resistance and small contact resistance are the keys for improving the current efficiency of 2.41%. Importantly, these devices exhibit excellent stability even after storage in air for 6 months without any protection.
