SOLAR ENERGY HARVESTING SYSTEM

摘要

Disclosed is a solar energy harvesting system comprising: a solar radiation redirecting layer, comprising an array of features with a sub millimetre scale, adapted to redirect solar radiation having a predetermined range of wavelengths; a solar radiation guiding layer for guiding solar radiation; wherein the system further comprises solar energy harvesting means adapted to convert solar energy into electric energy; where the solar radiation redirecting layer, redirects solar radiation with the predetermined range of wavelengths, towards the solar energy harvesting means. By providing the system with a solar radiation redirecting layer, a part of the solar radiation incident on the system is refracted with different angle allowing the refracted solar radiation to be guided within the solar radiation guiding layer towards the solar energy harvesting means. By using the solar radiation redirection layer to redirect the solar radiation, solar energy harvesting means having a smaller area can be used.
