A few nice Solar Cells images I found:
Erenn Ore- ‘Thin film solar cell’
Image by Engineering at Cambridge
This is a standard photo taken under a light microscope. It shows the delaminated layers of a thin film solar cell.
My research is on the development of thin film solar cells. I am using various combinations of materials as components of these solar cells. One thing I need to make sure of is that these materials are compatible with one another and that they stay on top of each other after being deposited. On certain occasions due to incompatibility of materials or material deposition conditions (temperature, pressure, etc), the layers do not stick to one other and start to delaminate. They help me to see the level and the location of delamination, which in return help me to find a solution to the cause of the problem in some cases.
