Bending light for a greater solar yield

New research at the Purdue University, Indiana has led to a viable means of using the internal structure of gem stones to amplify the efficiency of future solar cells by bending light; diffraction and reflection can increase the amount of energy harvested from the sun as current solar cells allow light to escape very easily, greatly reducing the use of solar technology as a capable source of energy versus current conventional energy generation methods like oil and gas which are both fast becoming limited.New research at the Purdue University, Indiana has led to a viable means of using the internal structure of gem stones to amplify the efficiency of future solar cells by bending light; diffraction and reflection can increase the amount of energy harvested from the sun as current solar cells allow light to escape very easily, greatly reducing the use of solar technology as a capable source of energy versus current conventional energy generation methods like oil and gas which are both fast becoming limited.
 
Synthetic crystals with a structure dubbed the 'inverse opal' along with its photonic crystals will help to reflect, diffract and bend light within the gem yielding more power from its exposure to solar radiation.
 
Purdue University's next goal is to incorporate this new, more efficient solar energy harvesting 'gem' into a system that is both efficient and inexpensive as current solar cells are currently not too efficient though cheap, even when utilising silicon wafer cells.
