Unlike conventional silicon panels that use thick layers of silicon, these solar cells use a simpler, less expensive approach — depositing an ultra-thin layer of cadmium and
The efficiency of Cadmium Telluride (CdTe) solar cells ranges from 8% to 22%, although their average efficiency is around 18%. The efficiency of CdTe solar cells is crucial as
In this paper, we design a new fi multijunction solar cell with 9-layer structure that has higher ef ficiency as compared to the 5-layer counterpart. The performance of cadmium
To increase efficiency further, ongoing research focuses on optimizing the material quality, improving the interface between different layers, enhancing light trapping mechanisms,

Success of cadmium telluride PV has been due to the low cost achievable with the CdTe technology, made possible by combining adequate efficiency with lower module area costs.
CdTe solar cells on the market currently reach up to 21.4% efficiency, with a lab record of 23.1% set by First Solar in 2024. Their low temperature coefficient helps maintain
SETO released the Cadmium Telluride PV Perspective Paper in January 2025, outlining the state of CdTe PV technology and SETO''s priorities to reduce costs, address materials availability,
These thin-film solar panels are less efficient than CdTe, achieving a 12-14% efficiency, but laboratory studies have recorded excellent efficiency results of 20.4%.
