Theoretical analysis and comparison of Third Generation Solar Cells

Under the condition that the traditional energy is continuously exhausted, the new round of energy crisis has formed a hot topic of discussion. So nowadays lots of scientists are devoted to recyclable energy area and solar cell, a kind of clean and recyclable energy, has become an academic which is worth studying. Solar cell has experienced major revolution for three times and now we have entered the era of the third generation of solar cells. In this essay, we firstly introduce three kinds of the third generation of solar cells in details then we get the conclusion that quantum dot is the most suitable and promising material to produce and doing further research for the third generation of solar cells by using some scientific manners and comparing their advantages and disadvantages. We hope that some drawbacks of quantum dot solar cell can be improved and practical quantum dot solar cell can be successfully manufactured in the following study.
