Since the solar spectrum is wider, the photon energy in sunlight is 0–4 eV. Essentially, the efficiency of a single solar cell for sunlight is much lower than that of a single solar cell for monochromatic light because a single semiconductor material cannot absorb sunlight of all wavelengths. The way to solve this problem, in theory, is very ...
