If you don't think the government should be artificially mandating winners and losers among clean energy companies with artificial subsidies, don't let that turn you off of basic research, where the real improvement in future clean energy will be made.A discovery by military and academic researchers that embedding charged quantum dots into photovoltaic cells can improve electrical output by enabling the cells to harvest infrared light, and by increasing the lifetime of photoelectrons, may mean dramatically increasing the amount of sunlight that solar cells convert into electricity. read more
