increasing solar pannel efficiency

right now solar efficiency is extremely low. that's because they are absorbing only the reddish part of the spectrum. well, surprise, the plants are using that spectrum to for photosynthesis. but they have found a way to transform the light of other spectra (usually, bluish, but it really depends on the plant) to the spectra that is used
my idea is in developing a special type of cover -glass for the solar panels, which transforms the wight light into the red light (not filters, transforms, meaning that there must be light length transformations going on in the glass). If that's done, solar panel efficiency should increase dramatically
