How about solar cell film

What are thin film solar cells?

Types and description Thin-film solar cells are the second generation of solar cells. These cells are built by depositing one or more thin layers or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic, or metal. The thickness of the film varies from a few nanometers (nm) to tens of micrometers (µm).

How to make a thin-film solar cell?

It doesn’t matter what type of thin-film solar cell you are making as they are all made the same way. All you need to do is to place the main PV material (a-Si, CdTe, or CGIS) between a sheet of conductive material and a layer of glass or plastic and Voila! You are ready to generate electricity.

How does a solar cell work?

In a typical solar cell, a single absorber with a bandgap near the peak of the solar spectrum is used, and any photons with energy greater than or equal to the bandgap can excite valence-band electrons into the conduction band to create electron-hole pairs.

Why are thin-film solar cells better than crystalline solar cells?

Due to this, thin-film solar cells are way thinner than the other contemporary technology, the conventional, first-generation crystalline silicon solar cell (c-Si). Crystalline silicon solar cells have wafers of up to 200 µm thick. Compared with the crystalline cells, thin-films are more flexible and lighter in weight.

What are thin film solar cells (TFSC)?

Thin film solar cells (TFSC) are a promising approach for terrestrial and space photovoltaics and offer a wide variety of choices in terms of the device design and fabrication.

Can thin-film solar cells reduce the cost of photovoltaic systems?

One of the main obstacles that came in the way of large-scale production and expansion of photovoltaic (PV) systems has been the steep price of the solar cell modules. Later, researchers developed one of the solutions to reduce this cost is by creating thin-film solar cells.
