Thin-Film Photovoltaic (PV) technology refers to the use of thin layers of semiconductor materials that convert sunlight into electricity. These films are typically deposited onto substrates like glass, plastic, or metal, resulting in flexible, lightweight solar cells. Thin-film photovoltaics include technologies like Cadmium Telluride (CdTe), Copper Indium Gallium Selenide (CIGS), Amorphous Silicon (a-Si), and emerging Perovskite and Organic Photovoltaics (OPVs).
Thin-film modules are gaining attention due to their potential for lower manufacturing costs, light weight, flexibility, and ease of integration into a variety of surfaces, including Building Integrated Photovoltaics (BIPV). However, they generally have lower efficiency than crystalline silicon solar panels, which limits their use in certain applications.
The global thin-film photovoltaic market was valued at USD 12 billion in 2023 and grew at a CAGR of 10% from 2024 to 2033. The market is expected to reach USD 31.12 billion by 2033.
