Japan develops the new day sensitization type solar battery
Pure professor of hillside plot of the university of island of Kyushu of Japan, developed the technology that could raise the day sensitization type power generating efficiency of solar battery a few days ago. It is reported, the resulting electricity increases by 14 times at most. Will cooperate with folk enterprise, will urge it to be practical as soon as possible.
The new technology uses several nanometers of diameter to gold corpuscle of several dozen nanometers. Taking out the surface of electrode of the electricity, the packed disposes gold corpuscle; The gold surface of corpuscle, spread make the light convert to the electric dyestuffs phthalocyanine, in order to increase to receive the photic surface area, raise the efficiency of power generating.
Professor YAMADA trial-produces the solar battery arranging corpuscle on the electrode of tin indium oxide, electric current produced after in order to study superficial irradiation. The optical switching in the visible light field of the wavelength 500 nanometer to 800 nanometer is the most effective; Current yield 1mW about 290 nanometers of resulting 700 nanometers of wavelength, it is far to increase by a wide margin 20 nanometers comparing with the time of there is no corpuscling.
Produce the space after the gold corpuscle heap, can increase the dyestuffs and shine the photic area. Meanwhile, will produce the so-called plasma phenomenon that metallic electrons shake collectively, it is said that has given play to the role of raising dyestuffs conversion efficiency too.
The ones that made the gold corpuscle shape and grew up 60 nanometer to 100 nanometer, diameter 10 nanometer to 20 nanometer are bar-shaped, photic wavelength of the electricity of active transition the most can be about nearing the infrared light of 1000 nanometers; And then change, for YinShi Cheng, find until 500 light reaction of wavelength best the intersection of painting and metal kind of dyestuffs by gold
Nearly infrared light has the properties of penetrating the organism, if can make and make gold corpuscle and nearly infrared light machines developed up, through the detect and utilizing, develop the discovery of cancer and treatment contributory medical equipment newly correctly contributing to of the electric current.
