Scientists have invented a solar battery made of wood Bashny.Net

Not so long ago experts from the University of Purdue have stated about the creation of a fundamentally new type of photovoltaic cells from natural substrates.

At the moment, organic solar cells applied to glass, plastic or paper. Each of these materials has its drawbacks. Innovative technology (the use of nanomaterials based on cellulose from wood) is the most environmental and effective.

Scientists have made a solar battery with the use of natural substrates, which has received the wood. These substrates processed in cellulose nanocrystals (Cellulоse Nаnocrystal; SPS), of which the experts made optically transparent lining. Light can easily pass through this material, after which it is absorbed by quite a thin layer of organic semiconductor.

These photovoltaic cells can be quickly recycled in water at the end of their life cycle.

 




At the moment, they demonstrate the energy conversion efficiency to the level of a mere 2.8 percent. It's nothing when you consider that available on the market solar panels have an efficiency of about 15 percent. But for products that can be obtained from renewable raw materials, is "an incredible achievement," the researchers said. Now they are searching for mechanisms that will give the opportunity to make new solar cells more efficient. Scientists seek to assess the efficiency of energy conversion at the level of ten percent.
