Antimony chalcogenide solar cells

Step up in performance

Antimony selenosulfides are promising photovoltaic materials but obtaining high-quality absorber layers is challenging. Researchers now show that layers deposited using a hydrothermal method have optimal bandgap, good morphology and favourable growth orientation, enabling solar cells with 10% efficiency.
