The limiting efficiency of an edgeilluminated multigap solar cell
Abstract
An edgeilluminated multigap photovoltaic system should show an efficiency greater than that attainable with only a single gap. The theoretical upper limit to the efficiency will occur as the number of different gaps goes to infinity. For this case a detailed balance limit analysis shows that at one sun the predicted efficiency is 64%, increasing with intensity to 81% at 10,000 suns. The effects of stimulated emission are included in the calculations but are found to be negligible.
