What Are CdTe Solar Panels? How Do They
Nowadays, CdTe technology is the most popular thin-film solar panel technology and it is the preferred option by the top
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, and support the scale-up of CdTe within the domestic utility-scale PV market. A large-scale solar array in Colorado with CdTe modules.
Solar energy has emerged as a promising renewable solution, with cadmium telluride (CdTe) solar cells leading the way due to their high efficiency and cost-effectiveness. This study examines the performance of CdTe solar cells enhanced by incorporating silicon thin films (20-40 nm) fabricated via a sol-gel process.
Nippon Sheet Glass Group is the preeminent supplier of this commodity, with a large factory (inaugurated in 2020) located near both First Solar and Toledo Solar in Lucky, Ohio. Recently, Vitro Architectural Glass agreed to supply TCO-coated glass to First Solar, expanding and upgrading their Carlisle, Pennsylvania plant.14
Recently, Vitro Architectural Glass agreed to supply TCO-coated glass to First Solar, expanding and upgrading their Carlisle, Pennsylvania plant.14 Supporting the growth, diversity, and scale of the domestic CdTe supply chain could reduce the production cost and increase the cost competitiveness of CdTe modules.
