OverviewComparisonFactors affecting energy conversion efficiencyTechnical methods of improving efficiencySee also

Energy conversion efficiency is measured by dividing the electrical output by the incident light power. Factors influencing output include spectral distribution, spatial distribution of power, temperature, and resistive load. IEC standard 61215 is used to compare the performance of cells and is designed around standard (terrestrial, temperate) temperature and conditions (STC): irradiance of 1 kW/m, a spectral distribution close to solar radiation through AM (airmass) of 1.5 and a cell temperature 25 °C. The resi
