Fill Factor Losses and Deviations from the Superposition Principle …
The presence of nonohmic internal series resistances in most thin-film solar cells has two consequences, namely 1) that the superposition principle [41, 46, 47] stops to be valid in thin-film solar cells and 2) that the measured series resistance is no longer a constant but a function of voltage and illumination.
The perils of solar cell efficiency measurements
The most common figure of merit for a solar cell is its power-conversion efficiency, which is defined as the ratio between the incident solar irradiance under standard illumination and the...
