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
The factors affecting energy conversion efficiency were expounded in a landmark paper by William Shockley and Hans Queisser in 1961. See Shockley–Queisser limit for more detail. If one has a source of heat at temperature Ts and cooler heat sink at temperature Tc, the maximum theoretically possible value for the ratio of work (or electric power) obt
