The power of a solar cell can be enhanced by 20 % with the help of nano-coatings, and the module power can be increased by 5 %. So far, solar modules have been able to convert only a certain range of the sun spectrum to electrical energy. With the help of their very special characteristics, the nano-coating applied by us bundles all incident rays. This has already been demonstrated on a laboratory scale and implemented successfully. The entire cell has been realised on a surface of 5 x 3 cm.
