The United States Department of Energy (DOE) grants millions of dollars for advancements in solar energy. Solar energy is a clean, abundant, widespread renewable energy source which can be used to generate electricity while decreasing greenhouse gas emissions. Solar cells are used to convert sunlight directly into electricity.
When the sunlight is absorbed by these solar cells, the solar energy knocks electrons off their atoms which will allow the electrons to flow through these cells to produce the electricity. This process is called photovoltaic effect. With the grants from the DOE, there is research to find more effective processes to use this photovoltaic effect. Competitiveness due to these grants will increase the effort to find practical and efficient uses of this process.
