Solar-cell efficiency

OverviewFactors affecting energy conversion efficiencyComparisonTechnical methods of improving efficiencySee alsoThe 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
