Comparing dye-sensitized solar cells
The hypothesis that silicon based solar cells are able to produce more power is proven to be true.
Dye-sensitized solar cells are are product of third generation of solar cell technology. Research shows that whilst silicon based solar cells are able to operate at 15% peak power production efficiency,dye-sensitized cells can achieve 11% compared to other thin film technology at only about 8%.
The experiment can be repeated by using different fruit juices such as blueberry or cranberry juice.
Try to repeat the experiment using a larger glass slide.
