Efficiency losses in the solar cell result from parasitic absorption, in which absorbed light does not help produce charge carriers. Addressing and reducing parasitic absorption is necessary to increase the overall efficiency and performance of solar cells (Werner et al., 2016a).
However, in cases where is above 0.1 eV, as increases from 0, the conversion efficiency first drops drastically from a value of 33%, and then increases almost linearly. At = 1, the conversion efficiency is nothing but that of a bulk solar cell with a bandgap of .
In general, taking the temperature rise into consideration, output efficiency of a solar cell drops remarkably especially for the CPV system if the heat generation is not well dissipated, reducing both the output photocurrent density and the output voltage. 4. Effects of cells' parameters on the loss processes
Our results suggest that drops of and conversion efficiency in QD solar cells may be caused by these intrinsic reasons as a result of fast carrier thermalization across the host material and QDs. for the absorption spectrum of a QD solar cell.

In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another. Terrestrial solar cells are measured under AM1.5 …

And in Fig. 6, Fig. 7, the efficiency of solar cells drops remarkably with the significant temperature rise, even though the concentration ratios are very low. So, reducing the angle mismatch loss via increasing the absorption angle is not effective unless the problem of temperature rise is well solved, which is also the critical problem of a CPV system. In addition …
