Cd1 S1
semiconductor· Cd1 S1
Cadmium sulfide (CdS) is a II-VI compound semiconductor characterized by a direct bandgap and high optical absorption in the visible spectrum. It is widely used in optoelectronic devices, photovoltaic applications, and photodetectors, where its tunable bandgap and strong light-absorbing properties make it valuable for converting light to electrical signals and vice versa. CdS remains relevant in thin-film solar cells, particularly in heterojunction architectures, though cadmium's toxicity has driven research toward cadmium-free alternatives in consumer applications.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
