3.4.4 Shockley-Queisser (SQ) Efficiency: Calculations

The efficiency of a solar cell determines how much of the solar power is converted to electrical power. In order to predict the solar cell efficiency before fabrication and to achieve a deeper understanding, different models have been developed for calculating the maximum energy conversion efficiency. This video shows how to calculate the Shockley-Queisser efficiency. As an example the case of the sun as a black body of 6000 K, the solar cell at 300 K and the silicon band gap of 1.12 eV are considered. The Matlab implementation is discussed. The effect of concentration is discussed and the results are compared to the Trivich-Flinn efficieny. This video is part of a course offered at Kiel University for advanced engineering bachelor students. Additional videos and exercise material are available in the course "Renewable Energy" on the Digital Learning Campus platform dlc.sh : https://dlc.sh/lernangebot/728 DLC registration is free of charge not only for students already registered at Kiel University, but also for prospective students who want to get to know Kiel University and consider transferring to Kiel University.
