The use of renewable energy sources such as the Sun, requires ongoing development of technologies and materials to increase the efficiency of the conversion from light to electric energy. A new class of molecules has been developed: it is increasing the efficiency of silica solar panels also protecting them from the solar radiation which can damage the lens of the eye. Surprisingly, the same molecules are used in the new generation of solar cells, the Graetzel cells. This new class of new fluorescent and very stable new compounds which could improve the performance of available cells and that of future generations.
Recent studies have been focussing on the use of these compounds for the opposite conversion, from electricity to light: devices such as LECs, LEDs or OLEDs are the cheaper and lower consumption versions for TV screens which contain molecules able to convert electric power into light through electroluminescence.
