WebbThe theoretical upper limit for high-efficiency solar cells is about 33.16% (±0.5%). There are currently commercially available multi-junction photovoltaic cells with efficiencies over 44%. NASA is working on a variety of technologies to achieve efficiencies greater than … WebbTo find the efficiency as a function of band gap, the above procedure is repeated for each band gap. There is an range of bandgaps for the optimum cell efficiency as shown in the graph below. Limiting solar cell efficiency as a function of the material bandgap for one-sun illumination. The calculations assume that the only recombination is ...
