A new coating for solar cells

The most effective to date, a variety of plastic solar cells are the bulk heterojunction elements, which consist of a semiconducting polymer ( an electron donor ) blended with fullerenes ( electron acceptors ), and two electrodes. Transparent anode, usually made of tin -doped indium oxide as the anode is used for the manufacture of metals such as aluminum.

The research team led by Professor. Robert Chang. (Robert Chang) proposed to cover the plate with a thin smooth layer of nickel oxide thickness of 5-10 nm, which is a good conductor of holes and electrons are effectively blocks. The new coating can increase the voltage of solar cells by 40% and increase the conversion efficiency of solar energy into electrical energy from 3-4 % to 5,2-5,6 %. In contrast to the alternative anode coatings, new coating is less expensive, electrically homogeneous and not subject to corrosion.
