Sol Solution has developed a patented "Rainbow Concentrator" lens that spreads and concentrates the spectrum with one inexpensive lens, allowing the concentrator cells to be tuned for specific wavelengths. We also have a patent pending Current Matched Multi-junction Solar cell and are currently working on improved optics for concentrator systems.
