Trying To Design The Most Efficient Solar Cells, Scientists Stumble Upon Photosynthesis

When Gabor’s team applied these simple models to the measured solar spectrum on Earth’s surface, they discovered that the absorption of green light, the most radiant portion of the solar power spectrum per unit wavelength, provides no regulatory benefit and should therefore be avoided. They systematically optimized the photocell parameters to reduce solar energy fluctuations, and found that the absorption spectrum looks nearly identical to the absorption spectrum observed in photosynthetic green plants.
