Solar Cell Efficiency

Solar cells intended for space use are measured under AM0 conditions. Recent top efficiency solar cell results are given in the page Solar Cell Efficiency Results. The efficiency of a solar cell is determined as the fraction of incident power which is converted to electricity and is defined as: (P_{max }=V_{OC} I_{SC} F F)
