Concentrating sunlight onto highly efficient solar cells

Not all photovoltaics are the same. Alongside normal solar modules, there are also other solar technologies. One of these uses lenses that focus and concentrate sunlight onto powerful solar cell stacks. This technology is being further developed in various research projects. Even the rainbow has a part to play.
