Understanding Solar Energy Conversion Efficiency. Solar energy conversion efficiency, denoted as η, is the ratio of the electrical power output (P_out) of a solar cell or module to the incident solar power (P_in) on the device''s surface. Mathematically, it can be expressed as: η = (P_out) / (P_in)

However, the variation in maximum FF can be significant for solar cells made from different materials. For example, a GaAs solar cell may have a FF approaching 0.89. The above equation also demonstrates the importance of the ideality factor, also known as the "n-factor" of a solar cell.
We emphasize here that solar cells based on such ultra-narrow c-Si layers can hardly compete with conventional (wafer-based) silicon solar cells in terms of conversion efficiency. We show in this work that the range of thicknesses 20–100 µm is very interesting for solar cell performance, as it may lead to conversion efficiencies that exceed
In order to address these challenges, we constructed two new evaluation methods to determinate the power conversion efficiencies (PCEs) of PSCs. The first setup is a solar simulator based on light emitting diodes (LEDs) allowing evaluation of the solar cells at wider range of light intensities, ranging from 102 to 10−3 mW·cm−2.
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.

The key characteristic of a solar cell is its ability to convert light into electricity. This is known as the power conversion efficiency (PCE) and is the ratio of incident light power to output electrical power.
