Photoactive layer

A photoactive layer is used in solar cells for absorbing light.

It can be found in all solar cells, but with different panels the photoactive layer is made of different materials.

The layer is found underneath the glass, adhesive, and reflection coating, but is the first required part of the cell.

[1] Photoactive means it can have a chemical reaction with sunlight and/or ultraviolet light.

For this to work the light must have a minimum energy depending on the cell to pass through.
