CdO
semiconductor· CdO
Cadmium oxide (CdO) is a direct-bandgap semiconductor compound with a cubic crystal structure, traditionally used in optoelectronic and photovoltaic applications. It is employed in thin-film solar cells, transparent conductive coatings, and photocatalytic devices, though its use has declined in many regions due to cadmium's toxicity and regulatory restrictions under RoHS and other environmental standards. Engineers may still encounter CdO in legacy systems, specialized research applications requiring high optical transparency combined with electrical conductivity, or in regions with less stringent material restrictions.

Regulatory Screening
Environmental
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.
