Once Again, Scientists Go Nano For Solar

Photovoltaic solar cells have their limits, and that’s directly related to the underlying semiconductor material. The scientists who discovered the limit back in 1961 named it after themselves, the “Shockley-Queisser (SQ) efficiency limit.” The not-so-favorable SQ prophecy basically states that single-junction silicon-based solar cells can convert no more than 33% of sunlight into working electricity.
