Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a solar cell, and more particularly to a cylindrical organic solar cell. [Previous technology] As the demand for energy increases and the global warming problem emerges, it is characterized by both sustainable and environmentally friendly scale energy. It includes wind, water, biomass, geothermal, seawater and solar energy. Over the years, I have received global attention and actively promoted this energy conversion technology and care. The solar g battery can directly convert the sun to the electric energy system, and does not require additional mechanical devices, so it is the most eye-catching. In 1954, the solar cell was completed by the Bell experiment in a semiconductor process and broke through the energy conversion efficiency of Peach. With the advancement of process technology and materials, many researches have been carried out in the direction of efficiency improvement, size reduction and process simplification. If the type of material is classified, the solar cell can be divided into single (four), multi-turn, amorphous Wei organic solar m (four) solar cell, although it has up to 20% of the world's scale and high stability, but the higher price is its ❹ # and On the way, the money of the low-country money, the solar-gas battery, and the dyed solar cells are gradually receiving attention. Since 1991, Professor EPFLM.Grazel published the 7% efficiency of organic solar cells in _丨, and the efficiency has been reached. The structure is the three-day monthly structure shown in Figure 1, which is composed of the upper substrate 10 and the lower substrate 12. The catalyst electrode 14, the electrolyte 16, and the semiconductor photosensitizing layer 18 are sequentially sandwiched in the middle. However, the light-receiving surface of this structure is incident from one side, so that the area of the receiving light source is greatly limited, resulting in insufficient ability to absorb sunlight. In view of the absence of the above-mentioned prior art, a novel cylindrical organic solar cell and a method of fabricating the same have been proposed to effectively overcome the above problems. 3 201039477 SUMMARY OF THE INVENTION The main object of the present invention is to provide a cylindrical solar energy solar cell whose closed-type transparent substrate is a light-receiving body, which can fully receive light at 36G degrees, so as to increase the amount of light received and can be continuously overlapped and set again. In order to increase the utilization rate of space and increase the efficiency of power generation. In order to achieve the above object, the present invention provides a cylindrical organic solar cell comprising: a hollow cylindrical lion outer coffee conductive substrate; a central cylindrical coffee layer conductive substrate accommodated in the hollow of the outer transparent conductive substrate a photosensitive layer, an electrolyte layer and a metal catalyst layer are sequentially disposed between the outer layer of the through-pole substrate and the inner layer of the conductive substrate; and - a sealed county between the outer transparent conductive substrate and the (10) conductive substrate The semiconductor photosensitizing layer, the electrolyte layer and the metal lining are sealed between the outer transparent conductive substrate and the (10) conductive substrate. Further, the hollow portion of the inner conductive substrate of the above-mentioned cylindrical organic solar cell can further accommodate another-group structure and the above-mentioned cylindrical organic solar cell phase-cylindrical organic solar battery.

The towel empty position 34 of the medical internal medicine substrate 24 can be filled with gas for cold hiding or cooling, and the temperature of the solar cell is prevented from being too high under the sun exposure, preventing the organic material and the electrolyte inside the battery from volatilizing and leaking, and prolonging the battery. life.
