AI Technical Summary

Problems solved by technology

[0003] Due to the limited number of PN junctions and the limited band gap, high quantum efficiency can only be achieved in a specific wavelength range, and high quantum efficiency cannot be obtained in the entire spectral range.

As for the method of improving the quantum efficiency by optimizing the PN junction, as the photoelectric conversion efficiency gradually approaches the theoretical limit, the cost of the traditional method that only targets photovoltaic power generation is gradually increasing, and the effect of efficiency improvement is becoming less and less significant.
