A recent study shows CdTe (Cadmium telluride) technology exhibiting some of the least environmental impact among solar cell technologies in India,
- The study was carried out by researchers at the Indian Institute of Technology (IIT), Mandi in Himachal Pradesh.
- CdTe has the lowest carbon dioxide emissions, ozone depletion potential, human health effects, and particulate air pollution.
- CdTe was one of five solar cell technologies on which the IIT scientists conducted a life-cycle assessment (LCA) to identify the most sustainable options for solar energy production in India. The other four were mono-silicon, polysilicon, Copper Indium Gallium Selenide (CIGS), and Passivated Emitter & Rear Contact (PERC).
- The Cadmium Telluride (CdTe) solar technology was first introduced in 1972 when Bonnet and Rabenhorst designed the CdS/CdTe heterojunction that allowed the manufacturing of CdTe solar cells.
