Researchers increase the efficiency of cheaper quantum dot solar cells
Quantum dot solar cells could offer a cheaper, more efficient alternative to conventional photovoltaic materials
Article Summary
Developing solar cells that are cheaper to produce and can harness the sun’s energy more efficiently are both important factors in ensuring the widespread use of solar energy to provide a clean alternative to fossil fuels in the future. Stanford researchers have found that adding a single layer of organic molecules can achieve both these goals by increasing three-fold the efficiency of quantum dot solar cells, which are cheaper to produce than traditional solar cells.
