A cellular solar cell panel

Abstract

The invention relates to a solar cell panel and especially a cellular solar cell panel. The cellular solar cell panel comprises an electric appliance function box and thin-film solar cell layers and is characterized in that a transparent substrate (7) in a profiled corrugated shape is disposed on a supporting frames (6) in shapes of connected hexagons, that the two sides of the substrate (7) are covered with the thin-film solar cell layers, that a base plate (5) is disposed on the bottoms of the supporting frames (6) and is equipped with a thin-film solar cell layer, that a frame (2) is disposed around the supporting frames (6) in shapes of connected hexagons, and that top of the frame is covered with a light-transparent plate (1). On this account, a photovoltaic effect generated by the cell layer absorbing top photoemission is enhanced and a cellular three-dimensional light-absorbing area of the profiled corrugated substrate is enlarged. Light absorption conversion ratio is over 39 percent. The cellular solar cell panel is easy to assemble, repair, and integrally replace and may achieve local replacement. In addition, the cellular solar cell panel is convenient to use and has high commercial popularizing value.

Description

technical field [0001] The invention relates to a solar battery panel, in particular to a honeycomb thin-film solar battery panel. Background technique [0002] With the tension and shortage of energy in the world, people pay more and more attention to the development of new energy, especially the development and utilization of solar cells that convert solar energy into electrical energy. Solar energy has been widely concerned and favored for its unique advantages such as no pollution, no geographical restrictions, and all-weather utilization. The market demand for new solar cells with large area, light weight and low production cost is increasing. Among the new solar cells, the currently commercialized crystalline silicon solar cells have the highest photoelectric conversion efficiency, but due to the limitation of material purity and preparation process, the cost is high, and it is difficult to improve the conversion efficiency or reduce the cost. Thin-film solar cells ca...

Problems solved by technology

[0003] Thin-film solar cells can be made of cheap glass, plastic, ceramics, graphite and metal sheets and other materials as substrates to form a thin film that can generate voltage. Generally, the thickness is only a few microns, so that under the same light receiving area, the thin film Compared with crystalline silicon solar cells, solar cells can greatly reduce the use of raw materials, and the thickness can be lower than 90% of crystalline silicon solar cells; however, the conversion efficiency of thin-film solar cells is only 13%, which is lower than 17% of crystalline silicon solar cells. , the manufacturing industry of thin-film solar cells has also been impacted by unbalanced phenomena such as overproduction and low market demand. Products cannot be quantified, which hinders the development of thin-film solar photovoltaic industry. However, compared with crystalline silicon solar cells, thin-film solar cells Solar cells have better power generation performance in low light conditions and have higher cumulative power generation

[0004] At present, the known solar modules, whether it is a crystalline silicon flat solar cell or a thin film solar cell, all absorb visible light between the two-dimensional planes of the unit to generate a photovoltaic effect to obtain voltage. When a planar solar panel receives light, two types of Light waste: one is the plane reflection effect, which will cause a large amount of light to be reflected and irradiated outside the solar panel; the other is refraction, that is, when the light hits a transparent or translucent solar panel, a large amount of light will escape through refraction , which greatly reduces the utilization rate of light, is an important factor restricting the improvement of solar power generation efficiency, and traditional solar panels are not conducive to replacement and maintenance, and are difficult to popularize and use
