Thin-film solar cells are a type of made by depositing one or more thin layers ( or TFs) of material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers () to a few microns () thick–much thinner than the used in conventional (c-Si) based solar cells, which can be up to 200 μm thick.

What is the future of thin film solar cells?
The exploration of emerging materials and technologies represents a dynamic frontier in the field of thin film solar cells. Among the most promising advancements are perovskite solar cells and quantum dot solar cells, which offer unique properties and potential applications in solar energy generation.
What is a thin film solar cell?
Thin film (<10 μm) solar cells are more akin to a coating than to free-standing cells. Therefore, if they can survive cell processing conditions (for example, the use of solvent, high temperatures or plasma), assembly materials can also be used as substrates for cell fabrication.
Are thin film solar cells suitable for a multi-junction structure?
Thin film cell technologies that can be easily implemented in a multi-junction structure are therefore highly desirable. In a multi-junction solar cell, cells with different bandgaps (highest on the Sun-facing side) absorb different parts of the solar spectrum, minimizing sub-bandgap and thermalization losses.
Can thin films be used in solar technology?
The concept of utilizing thin films in solar technology dates back several decades, with researchers initially focusing on alternative materials and fabrication techniques to overcome the limitations of conventional crystalline silicon solar cells.
