Open-Circuit Voltage
The above equation shows that V oc depends on the saturation current of the solar cell and the light-generated current. While I sc typically has a small variation, the key effect is the saturation current, since this may vary by orders of magnitude. The saturation current, I 0 depends on recombination in the solar cell. Open-circuit voltage is then a measure of …

Spectral Response
The spectral response is conceptually similar to the quantum efficiency. The quantum efficiency gives the number of electrons output by the solar cell compared to the number of photons incident on the device, while the spectral response is the ratio of the current generated by the solar cell to the power incident on the solar cell. A spectral response …
Theoretical Calculation of the Efficiency Limit for Solar Cells
With reference to table 1 we can clearly see that the record open circuit voltage under one-sun condition (C =1) of gallium arsenide solar cell (1.12 V) is already close to the SQ limit (1.17 V) while silicon solar cell is still behind with a record V oc of 0.706 V compared to a limit of 0.893 V, this difference is due to the fact that GaAs has ...
