R&D in Solar cell efficiency gains momentum

In a study published in this week’s Journal of the American Chemical Society, UCLA researchers developed a new plastic that could be an important step in creating more flexible and affordable solar cells. On the other hand MIT has used computer modeling to design thin-film crystalline silicon cells that could be up to 50 percent more efficient than today’s commercial offerings. They have an antireflective coating on the front, and layers of reflective coatings, plus tightly-spaced lines called diffraction grating, on the back.
