Do you want to get the best efficiency

Professor Wu said, “If you want to get the best efficiency VGP-BPS8, VGP-BPS8A, you need to consider that you can get the voltage and current.” Voltage is a kind of material can provide the potential energy; current is the amount of material able to transmit the charge. He said, “If you can absorb a very wide range of wavelengths, then you will have to sacrifice voltage. If you absorb the energy limit is very high, you can get a high voltage, but you had to sacrifice current. Our idea is to find a balance. ”
Since the sixties the VGP-BPS9, VGP-BPS9/B twentieth century, since the silicon solar cells have emerged. Since the nineties the twentieth century, scientists began developing dye-sensitized solar cells. In the dye-sensitized solar cells, dye molecules cover the tiny metal oxide particles have lived, and along with insert a thin film. Dye molecules capture light energy and release electrons, while the metal oxide particles was more like a wire, the electronic transmission to the circuit.
But the VGP-BPS9/S, VGP-BPS9A/B electronic transfer between particles may be lost. Professor Wu is being designed that will be tiny nanowires to merge in order to be transmitted directly to the electronic circuit causes. Last year, he and his research team in the “Physical Chemistry B” magazine published a paper describing containing particles and titanium oxide nano-line dye-sensitized solar cells. This dye-sensitized solar cell efficiency of 8.6%, or about the commercial application of silicon solar cell inspiron e1405 battery efficiency of 15% of the half.
