The invention has the advantages that: sunlight which does not irradiate the photo-anode film on the photo-anode substrate is recovered through the light guide pipe, and the full spectrum of the sunlight is introduced into the photo-anode film, so that the photo-anode film receives more sunlight, and the photoelectric conversion efficiency of the solar cell is improved.
Description
Technical Field
The invention relates to the field of solar cell preparation, in particular to a light pipe interpenetrating internal lighting solar cell, a preparation method and contents thereof.
Background
The solar cell is of various types, mainly simulating the photosynthesis principle, wherein the film preparation of the solar cell is crucial. The preparation of the film promotes the solar cell to simulate the photosynthesis of plants in the nature by utilizing solar energy at lower cost, and the solar energy is converted into electric energy.
The photoelectric conversion process in the solar cell is complicated, and the factors determining the photoelectric conversion efficiency are many, wherein the selection of the anode thin film is a crucial part. Early research in this regard was mainly focused on flat-plate electrodes, which had the major disadvantage that only a single layer of dye molecules could be adsorbed on the surface of the electrode, and the efficiency of absorbing sunlight was very low, and the photoelectric conversion efficiency could not be improved. In order to overcome the defects of a single-layer dye, a nano-porous titanium dioxide film conductive film is introduced later, so that the whole semiconductor film like a sponge has a large internal surface area and can absorb more dye monomolecular layers, the defect that the original battery can only absorb the monomolecular layers and absorb a small amount of sunlight is overcome, the sunlight can be reflected in the film for multiple times, the sunlight is repeatedly absorbed, and a larger photocurrent can be generated.
Although the photoelectric conversion efficiency is improved when the sunlight irradiates the porous film, the sunlight intensity is exponentially attenuated due to the strong absorption of the sunlight by the dye, some electrolyte and the like, and the original porous film has a certain thickness, so the sunlight hardly irradiates the tail end of the film. The existing solution is to add a large-particle reflective layer at the rear end of the surface of the film, but this reflective layer refracts the attenuated light back into the film. The folded light intensity is weak, and meanwhile, because the front section absorbs the maximum absorption spectrum completely, some red light with weak absorption and long wavelength is left, and the full-spectrum sunlight transmitted by the novel film of the invention is not achieved; in addition, due to the requirement of the traditional solar cell packaging electrolyte, a blank part except for the film is often left to facilitate packaging of the electrolyte, and the area of the blank part is not utilized all the time, so that a considerable amount of space is wasted.
Disclosure of Invention
The invention aims to provide a light pipe interpenetrating internal lighting solar cell, which increases the illumination quantity of a photo-anode film by changing the structure of the photo-anode film, thereby improving the photoelectric conversion efficiency of the solar cell. The blank area lost by the non-photoanode film on the photoanode substrate is fully utilized, sunlight is introduced into the photoanode film through the light guide pipe, and then the photoanode film can receive more sunlight irradiation.
The invention is realized in this way, a new solar battery of light pipe interpenetration internal lighting, mainly by the photoanode basement; a photocathode substrate; and (4) electrolyte composition. The method is characterized in that: the blank position of the substrate on which the photo-anode film is positioned introduces sunlight which does not irradiate the film into the photo-anode film through a light guide pipe; the sunlight is recycled through the optical fibers and does not irradiate the anode film, the sunlight enters the nanometer scattering tube after being totally reflected in the nanometer optical fibers at the two ends, and enters the photo-anode film through the scattering of light in the nanometer scattering tube to form a photo-anode substrate together with the anode film; and with the photocathode substrate; the electrolytes together constitute a solar cell.
The semiconductor film is coated on the photo-anode substrate, then the nano optical fiber is connected with the blank part of the non-semiconductor film, the nano scattering tube is inserted into the semiconductor film, and the two ends of the nano scattering tube are connected with the other end of the nano optical fiber connected with the blank part, so that the light pipe interpenetrating internal illumination film is formed by the nano scattering tube and the anode semiconductor film.
Compared with the existing laboratory test technology, the invention has the following beneficial effects:
1. the sunlight enters the middle nanometer scattering tube after being totally reflected by the nanometer optical fibers at two ends, and the nanometer scattering tube scatters the light to the light anode film, so that the traditional mode that the sunlight irradiates the light anode film is successfully changed.
2. The light pipe is used to construct the light pipe interpenetrating thin film lighting thin film, and the original light-capturing mode of the photo-anode thin film is changed.
3. The light pipe interpenetrating thin film lighting film is introduced to enable the sunlight to irradiate the tail end of the thin film which cannot be irradiated by the original sunlight, and the sunlight full spectrum is introduced into the thin film, so that the sunlight irradiates the tail end of the thin film.
4. The light pipe is used for constructing the light pipe interpenetrating thin film lighting film, can be used for various solar cells, and solves the problem that the photoelectric conversion efficiency is difficult to improve.
