Factors Affecting Conversion EfficiencyDetermining Conversion EfficiencyAdditional InformationNot all of the sunlight that reaches a PV cell is converted into electricity. In fact, most of it is lost. Multiple factors in solar cell design play roles in limiting a cell''s ability to convert the sunlight it receives. Designing with these factors in mind is how higher efficiencies can be achieved. 1. Wavelength—Light is composed of photons—or p...See more on energy.gov
