Conventional solar cells made from crystalline silicon are difficult and energy-intensive to manufacture. Organic solar cells are cheaper, but have always produced less electricity. Why this is so has never been fully explained. Now, a method developed by HZB researchers reveals that current flow inside a solar cell can be affected by the spin of the charge-carrying particles.
