Abstract
A kind of technology for preparing chlorophyl photovoltaic cell belongs to the organic photovoltaic battery production technology.This technology characteristics is with the saturating electro-conductive glass of tin ash light chlorophyll a to be spread on the negative plate with electrodeposition process as battery lead plate, sandwiches the polyvinyl alcohol film that contains quinhydrones between two plate plates.This technology is simple and easy to do, the evil of the no three wastes.By the chlorophyl photovoltaic cell that this technology makes, cost is low, the photoelectric parameter height.
Description
The invention belongs to organic photovoltaic battery preparation technology.
The development of chlorophyl photovoltaic cell is solar energy to be converted to one of key areas that the solar energy of electric energy utilizes, and reported in literature is to be electrode with two kinds of different metals at first, and chlorophyll a is sandwiched between two electrodes.People's such as C.W.Tang research, be adopt on quartz plate metalling technology prepare chlorophyl photovoltaic cell (Journal of Chemical Physics, 1975,62,2139-2149).But the short circuit current of this kind battery is low excessively, and needs the high-temperature vacuum metalling in the preparation process twice, has increased preparation technology's difficulty, and chlorophyll a is wrecked.In recent years, people's such as Kuku Uehara research is as battery lead plate with two saturating conductive films of light with tin indium oxide (or gold) of sprawling, adopt therein one to smear chlorophyll a, the technology that between another electrode plate, adds polyvinyl alcohol film, form chlorophyl photovoltaic cell (Chemistry Letters, 1984, pp 1499-1502).The short circuit current of this kind battery obviously increases, and has also removed the metalling process among the preparation technology from, but owing to used the saturating conductive film of light of tin indium oxide (or gold), makes the battery cost too high.
The present invention is directed to the deficiency of existing technology, propose a kind of metalling process that can remove among the preparation technology, also can keep high short circuit current, the preparation technology of the chlorophyl photovoltaic cell that can also reduce cost.
Design of the present invention is to utilize the saturating electro-conductive glass of tin ash light, directly forms negative pole at this electro-deposition chlorophyll a on glass, and the saturating electro-conductive glass of another piece tin ash light as positive pole, is added the homemade polyvinyl alcohol film that contains quinhydrones between the two poles of the earth.
Utilize the chlorophyl photovoltaic cell of this prepared, V
OcBe 135～150(mv), I
ScBe 68～152(NA/CM), do not need the formality of high-temperature vacuum spraying plating gold in the preparation process, whole technology is easy, the evil of the no three wastes, and the battery lead plate area can be at 10 * 10cm
2In, cheap.
This process implementing process: at first, with the saturating electro-conductive glass of tin ash light is negative electrode, aluminium flake is an anode, the isooctane solution that contains chlorophyll a is an electrodeposit liquid, put into galvanic deposition cell, the voltage strength at the two poles of the earth is 800～1500V/CM, switches on and takes out after 5-20 minute, promptly make and have the saturating conductive glass electrode plate of the tin ash light of sprawling chlorophyll a, this battery lead plate is as the negative plate of battery.Add hydroquinone solution again in polyvinyl alcohol water solution, uniform spreading is on the polymethyl methacrylate sheet, and promptly getting thickness behind the evaporate to dryness is the polyvinyl alcohol film that contains quinhydrones of 0.01～0.08mm.Get the positive plate of the saturating electro-conductive glass of another piece tin ash light then as battery, under with water-moistened situation, with the polyvinyl alcohol film uniform spreading that contains quinhydrones that makes above on this positive plate.At last, make the polyvinyl alcohol film closure of the chlorophyll a and the positive plate of negative plate, promptly making with the saturating electro-conductive glass of tin ash light is battery lead plate and the chlorophyl photovoltaic cell that contains quinhydrones.
