United States University of Utah design multicolor thin-layer enhance the efficiency of photovoltaic cells

Polaris solar PV net news: United States University of Utah researchers have claimed to have devised a multicolor thin-layer to gather light. Researchers noted that the transparent glass coverslip or plastic layer melted into solar panels, can contribute to increased overall conversion efficiency of solar cells to 50%.

Conventional solar cells can only absorb a narrow band of light, cannot bring other bands of light. In the new study, RajeshMenon, Assistant Professor of electrical and computer engineering and electrical engineering Grad PengWang designed a multi-color layers that they enable more wavelengths of light absorbed by the photovoltaic cells, thus contributing to the photovoltaic conversion efficiency of 16%.

Researchers have also designed a multi-color computer simulators, to put solar panels (with eight different absorption layer). Experiments showed that 50% more theoretical conversion efficiency of photovoltaic cells.

“These colors can be absorbed by the appropriate solar cells, without increasing the cost of context improved battery efficiency. , “Menon said.

Menon said the multi-color 10 mm in length, 50 mm wide, and equipped with 3 µg m wide grooves reflect incoming light. Substantially in accordance with the theory of multi-color layers formed a Photolithography manufacturing. However, the manufacturing cost is not expensive to simply build a multicolor stencil, and then blanked out like DVD.

Menon said the next step will be to cooperate with solar cell maker, University of Utah, planned for the next 5-10 years in the production of this highly efficient solar cells.

Menon and his team also plans in the United States national renewable energy laboratory to test this new technology.
