WebJul 14, 2014 · The Shockley-Queisser limit has now attained major significance with the steep increase of research in this area and the use of solar energy. In 1956, Shockley, along with Walter H. Brattain and John Bardeen, was awarded the Nobel Prize for Physics “for their researches on semiconductors and their discovery of the transistor effect”. WebIn this paper, we develop an intuitive but powerful graphical approach called the Shockley–Queisser triangle (S-Q triangle). This approach unifies the thermodynamic …

WebThe Shockley–Queisser Triangle The scaling analysis presented in this paper relies on two key observations related to the voltage and the current needed to produce the maximum output power of a solar cell, i.e., maximum power-point voltage (Vmp) and maximum power-point current (Imp). The Shockley–Queisser limit is calculated by examining the amount of electrical energy that is extracted per photon of incoming sunlight. There are several considerations: Blackbody radiation Any material, that is not at absolute zero (0 Kelvin), emits electromagnetic radiation through the black-body … See more In physics, the radiative efficiency limit (also known as the detailed balance limit, Shockley–Queisser limit, Shockley Queisser Efficiency Limit or SQ Limit) is the maximum theoretical efficiency of a solar cell using … See more It is important to note that the analysis of Shockley and Queisser was based on the following assumptions: 1.
