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 a single p-n junction to collect power from the cell where the only loss mechanism is radiative … Visa mer 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, and the other a p-type semiconductor, … Visa mer It is important to note that the analysis of Shockley and Queisser was based on the following assumptions: 1. One electron–hole pair excited per incoming photon 2. Thermal relaxation of the electron–hole pair energy in excess of the band gap Visa mer 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: Visa mer • Thermodynamic efficiency limit Visa mer • Reproduction of the Shockley–Queisser calculation (PDF), using the Mathematica software program. This code was used to calculate all the … Visa mer WebbThis study was based on the analysis of the paper “Detailed Balance limit of Efficiency of p-n Junction Solar Cells” written by William Shockley and Hans J. Queisser. This study starts with a small introduction on the solar cells’ parameters and calculation of efficiency from IV characteristic curve and then it goes more deeply into the Shockley-Queisser paper …
