1.
Cheaper to produce than crystalline silicon but not as efficient
2. Traditional solar cells are made up using 300-400micrometre thick wafers, however these cells generate 90% of its energy from the top 15-20 micrometres of the cell. The rest of the cell is used as support.
3. Thin Film technology consists of depositing a thin layer of semiconductor onto an already present surface (glass window, roof panels)
4. We’ve seen them as solar powered calculators and watches
5. The material uses an amorphous silicon, which is of lower grade only 8% efficient (currently) to the traditional flat plate collectors. Amorphous cells usually degrade with continued exposure to sunlight, but new developements are fixing this problem.
