Shockley–queisser theory
Shockley and Queisser's work considered the most basic physics only; there are a number of other factors that further reduce the theoretical power. Limited mobility [ edit ] When an electron is ejected through photoexcitation, the atom it was formerly bound to is left with a net positive charge. 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. One … See more • Reproduction of the Shockley–Queisser calculation (PDF), using the Mathematica software program. This code was used to calculate all the graphs in this article. • Luque, Antonio, and … See more In a traditional solid-state semiconductor such as silicon, a solar cell is made from two doped crystals, one an n-type semiconductor, which has extra free electrons, … See more 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: See more • Thermodynamic efficiency limit See more WebAccording to Shockley-Queisser and Ruhle limit, the maximum PCE is achieved when E g equals ∼1.1 and 1.3 eV, respectively [31], [32]. Shockley and Queisser calculated the efficiency limit for a single junction solar cell based on the assumption that the sun spectrum can be approximated by black body radiation with a temperature of 6000 K.
