Practical implementation of spectrum splitting for solar cells

In the past decade, a number of inventions have been patented, describing all a different technology to achieve spectral beam splitting for solar cells. This paper describes a novel light splitting device, that could solve some of the additional problems encountered by previous inventions, such as no overlap in photon frequencies, no moving parts, lightweight and lower influence by tracking errors. The practical optical efficiency of our device was calculated using available materials. Although there is still room for improvements, a calculated practical optical efficiency of 66% is reached.status: publishe
