Solar cell panel

Abstract

The invention provides a solar cell panel, belonging to the technical field of semiconductor devices. The invention solves the problems that energy is wasted, photo-electrical conversion efficiency and power are reduced, and the like as the traditional solar cell panel adopts a single-face light absorption way and partial received optical energy is lost after passing through a panel body. The solar cell panel comprises an upper photoelectric reaction layer and a lower photoelectric reaction layer, wherein a light transmitting isolated layer is arranged between the two photoelectric reaction layers, a plurality of photoelectric conversion regions are regularly arranged on the photoelectric reaction layers, the upper photoelectric conversion regions and the lower photoelectric conversion regions are arranged in a staggered way, and the outer sides of the two photoelectric reaction layers are respectively correspondingly provided with a light ray anti-reflection layer which can focus external radiation energy into the photoelectric conversion regions. By adopting the solar cell panel provided by the invention, light rays can simultaneously permeate from the upper side and the lower side, and photoelectric conversion is carried out repeatedly, thus the cell panel can collect the light rays more effectively under the illumination conditions of the same area and the same intensity, the energy can be fully utilized, and high-efficiency photoelectric conversion efficiency and power can be realized.

Description

technical field [0001] The invention belongs to the technical field of semiconductor devices and relates to a solar battery panel. Background technique [0002] With the increasing pressure of energy crisis and environmental pollution, people are more and more urgent to develop new energy, among which the cleanest, most environmentally friendly and cheapest is undoubtedly solar energy. People use solar energy mainly in the form of photoelectricity, photothermal and photochemical, among which there are more and more forms of using solar energy to generate electricity. The solar panel is the core part of the solar power generation system, and it is also the most valuable part of the solar power generation system. Its function is to convert the solar energy into electrical energy, or store it into the battery, or promote work load. [0003] At present, the currently used solar panels are mainly single-sided solar panels. For example, Chinese patent documents have disclosed a ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned high-efficiency solar photovoltaic cell panel performs single-sided photoelectric conversion through the top surface, so it cannot receive and utilize the light energy projected on its bottom surface from other directions in the space. A one-time absorption reaction is carried out, so that part of the received light energy is lost through the plate body, resulting in waste of energy, reducing the conversion efficiency and power of photoelectricity, thus limiting the use of the above-mentioned battery plate in automobiles, aerospace, Military, construction, lighting, transportation and other occasions that require particularly efficient power conversion
