Question

The Shockley-Quiesser limit suggests that a single junction solar cell has an efficiency that can reach 100% when the sun is overhead True False

Answer 1

Answer :- The statement , " The Shockley-Quiesser limit suggests that a single junction solar cell has an efficiency that can reach 100% when the sun is overhead " is FALSE.

Shockley-Quiesser limit suggests that a single junction solar cell has an efficiency that can reach 33.7% when the sun is overhead. This maximum occurs at a band gap - 1.34 eV. So even if all the power of sunlight is falling on ideal solar cell, the 337 W/m² would be converted to electricity.
