AI Customer ServiceThe conversion efficiency of a solar cell with a spectral converter that employs down-conversion can be calculated in the same way as performed for the single-junction solar cell explained in Sect. 6.1.

Power Conversion efficiency simulation. Optical simulation. Organic solar cells. This work presents the simulation of the power conversion efficiency of organic solar cells (OSCs), as well as the optimization of the thickness of active layer for better efficiency. The simulated OSCs uses P3HT: PCBM polymer as an active layer.
The calculations are performed for 1 sun illumination ( X = 1). The conversion efficiency of the single-junction solar cell is shown in Fig. 6.33. Compared to the result for AM1.5G, the conversion efficiency during cloudy weather is smaller. The maximum conversion efficiency is 31% at Eg = 1.39 eV.
In order to improve the solar cell conversion efficiency, we have to make best use of the sunlight, which broadly distributes in the range from the ultraviolet to the infrared.
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.
A maximum conversion efficiency of 49.4% is reached for a band-gap energy of 2.43 eV between the conduction band and the valence band, and an energy gap of 1.49 eV between the valence band maximum and the intermediate-band quasi-Fermi level Conversion efficiency of the intermediate-band solar cell (AM1.5D, maximum concentration).
