“…If we bear in mind that in a real situation the solar cell does not operate always in maximum concentration and the solid angle under which the cell sees the sun is in fact only a minute fraction of a hemisphere, the maximum efficiency is not larger than 12.79%, which is actually lower than most recently fabricated solar cells. However, we can conclude that solar cell is a quantum converter and cannot be treated as a simple solar radiation converter [5].…”

“…While the latter is indeed very expensive, it would appear that spectral splitting can be done at relatively low costs and, thus, is the approach to which MEG should be compared. If we recall that the ''photon splitting'' concept shows a 42% Shockley-Queisser limit for a (1.9+1.0 eV) two band gap solar cell [36,38] (and a higher one for more than 2 bandgaps), another factor should be considered. The problems that beset the ''photon splitting'' concept are rather well-known basic engineering and production ones [37].…”

“…In the radiative limit, n = 1 (per junction) and

J_{0} = \frac{2 π q}{h^{3} c^{2}} \int_{E_{g}}^{\infty} \frac{E^{2}}{e^{E / k T} - 1} d E \approx \frac{2 π q k^{3}}{h^{3} c^{2}} T^{3} \cdot ({(E_{normalg} / k T)}^{2} + 2 E_{normalg} / k T + 2) \cdot e^{- E_{normalg} / k T} \approx \frac{2 π q k}{h^{3} c^{2}} T \cdot E_{normalg}^{2} \cdot e^{- E_{normalg} / k T}

where c is the speed of light and h is Planck's constant. (The approximation e E/kT >> 1 in the denominator of the integrand is accurate to better than one part in 10 8 for E g > 0.5 eV.)…”

The basis for the temperature dependence of the principal performance parameters of single and multi‐junction concentrator solar cells is examined, focusing on the impact of bandgap and irradiance. The analysis of cells in the radiative limit establishes fundamental bounds. A quasi‐empirical model yields predictions consistent with available data. A simple method for estimating the temperature coefficients of key performance parameters is identified. The degree to which the efficiency penalty associated with cell heating can be mitigated by high irradiance is also evaluated. Copyright © 2012 John Wiley & Sons, Ltd.
