In this articleÂ­, we will examine solar cells to learn how they convert the sun's energy directly into electricity. In the process, you will learn why we're getting closer to using the sun's energy on a daily basis, and why we still have more research to Â­do before the process becomes cost-effective.n this articleÂ­, we will examine solar cells to learn how they convert the sun's energy directly into electricity.
