Daniely Reis Santos recently published in collaboration with dr. Sudhanshu Shukla and prof. Bart Vermang  a review on the crystal and energetic structure, optoelectronic properties, recent advances in synthesis methods, and experimental realization of devices based on CBS-based devices. the Cu₃BiS₃ compound exhibits excellent optical absorption characteristics and suitable bandgap for solar cell and photoelectrochemical applications. CBS offers new opportunities for both domains. Although photovoltage limitations have hampered the development of CBS-based solar cells, promising results on photoelectrochemical water splitting have opened new avenues. More complex photoelectrochemical reactions, such as CO₂ reduction can be targeted with modified interfaces and surfaces. Nevertheless, fundamental studies with innovative device designs are required to fully harness the potential of the CBS absorber. The development of an effective and stable visible light active photocatalyst is crucial to achieve high efficiency in (photo)electrochemical reactions.
