Applications and Implications
Second generation of photovoltaic (PV) solar cells
Description
Thin-film solar cells are made by depositing one or more thin layers of photovoltaic material onto a substrate, such as glass, plastic, or metal. They are typically a few nanometers to a few microns thick, much thinner than conventional crystalline silicon based solar cells.
Types
Commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si).
Advantages
Lighter and more flexible than first-generation silicon solar cells, suitable for building-integrated photovoltaics, semi-transparent photovoltaic glazing, and in some of the world's largest photovoltaic power stations. Materials used are produced using simple and scalable methods, leading to lower environmental impacts.
The versatility of thin-film solar cells enables a wide range of applications, from wearable technology to emergency power solutions and integration into built environments. These lightweight, flexible cells can be seamlessly incorporated into clothing, easily deployed in disaster recovery operations, and applied to building surfaces, vehicles, and even spacecraft
