Caffeine gives solar cells an energy boost

Scientists have discovered that caffeine can help make a promising alternative to traditional solar cells more efficient at converting light to electricity. Their research may enable this cost-effective renewable energy technology to compete on the market with silicon solar cells.


Creating Multi-Junction Solar Cells from Off-the-Shelf Components

Multi-junction solar cells are both the most efficient type of solar cell on the market today and the most expensive type of solar cell to produce. In a proof-of-concept paper, researchers from North Carolina State University detail a new approach for creating multi-junction solar cells using off-the-shelf components, resulting in lower cost, high-efficiency solar cells for use in multiple applications. Multi-junction, or
