PV array made of cadmium telluride (CdTe) solar panels Cadmium telluride (CdTe) photovoltaics is a photovoltaic (PV) technology based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity.
Cadmium telluride solar cells are the world’s leading thin-film photovoltaic technology. As of 2023, global installed capacity has surpassed 30 GWp, with about 40% of that capacity located in the United States. Their architecture can be simplified into several stacked layers, from bottom to 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.

Cadmium telluride photovoltaic cells have negative impacts on both workers and the ecosystem. When inhaled or ingested the materials of CdTe cells are considered to be both toxic and carcinogenic by the US Occupational Safety and Health Administration.
The Palestine Power Generation Company continues to plan for the establishment of a combined-cycle power plant with a total capacity of up to 450MW each on a Build Own and Operate (BOO) basis. Implementation of the 250MW first phase will involve a pilot project at a total cost of $344 million in the North of the West Bank.
When Hasan first looked into the possibility of using wind energy to generate electricity in Palestine in 1991, he came to the conclusion that areas with an elevation of 850 meters or more, including Ramallah and Jerusalem, have excellent energy potential . In some areas of the WB, wind energy may be produced at 0.07 $/kWh .
Future consumption of electricity is expected to reach 8,400 GWh by 2020 on the expectation that consumption will increase by 6% annually. The Palestinian Electricity Transmission Company (PETL), formed in 2013, is currently the sole buyer of electricity in the areas under Palestinian Authority (PA) control.
Israel required Palestinian power companies to sell their electricity at low rates fixed by the government. Unlike the IEC, these companies lacked the state subsidies and economies of scale to sell electricity at fixed prices profitably.
Recent installations of large First Solar CdTe PV systems were claimed to be competitive with other forms of solar energy: First Solar's 290- megawatt (MW) Agua Caliente project in Arizona is one of the largest photovoltaic power station ever built.
How Do They Compare to Other Panels? 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. At first, CdTe panels achieved a 6% efficiency, but the efficiency has tripled to this day.
CdTe PV modules provide a beneficial and safe use for cadmium that would otherwise be stored for future use or disposed of in landfills as hazardous waste. Mining byproducts can be converted into a stable CdTe compound and safely encapsulated inside CdTe PV solar modules for years.
Nowadays, CdTe technology is the most popular thin-film solar panel technology and it is the preferred option by the top manufacturers of thin-film solar panels in the world. In this article, we will do a deep dive on CdTe solar panels and everything related to this technology.
