Laser type solar battery

Abstract

The invention relates to a technology aiming at solving such defects of the prior solar battery that light energy conversion rate is low, and provides an intensive laser type solar battery. The technical proposal adopted is that one-way mirrors for focusing sunlight are respectively arranged above and below the solar battery. The one-way mirror uses principles of a pseudo-sandwich ruby laser and principles of other lasers for focusing the sunlight. The optimum proposal is that the solar battery is arranged on a solar battery board, a plurality of solar batteries are arranged on the solar battery board, one-way mirror cluster frames are arranged above and below the solar battery board, and a plurality of one-way mirrors corresponding to the solar batteries of above and below one by one are arranged on the frames. As the principles of the pseudo-sandwich ruby laser and the principles of other lasers are used for focusing sunlight, the light energy conversion rate is improved greatly.

Description

technical field [0001] The invention relates to a solar cell, in particular to a laser type solar cell. Background technique [0002] A solar cell is a solar / electric energy conversion device. In today's increasingly prominent energy problems, solar power generation technology is one of the fastest-growing and most dynamic research fields in recent years. In recent decades, the first-generation crystalline silicon high-efficiency solar cells and the second-generation thin-film solar cells have made remarkable achievements. However, its high cost is still the main factor restricting the large-scale application of photovoltaic power generation. In order to reduce the cost of photovoltaic power generation, some developed countries in foreign countries are competing to develop concentrating photovoltaic cells, that is, by using cheap concentrating systems to concentrate sunlight to high-performance photovoltaic cells with a small area. This not only helps to improve the conve...

Problems solved by technology

However, the solar tracking device of this type of concentrating photovoltaic cell is a huge system with complex structure and high cost! This kind of traditional solar cell is equipped with a concentrating system such as a lens and a reflector to form a concentrating solar cell. Since the sunlight received on the large light-receiving surface of the concentrating system is concentrated to a traditional solar cell with a lower manufacturing cost and a smaller area battery, thereby greatly reducing the cost of solar cell manufacturing

However, this kind of solar cell has a very small receiving field of view. In actual use, a sun tracking system needs to be configured, which not only increases maintenance costs, but also cannot receive background light, which greatly reduces the utilization efficiency of sunlight.

Especially when the surrounding environment is harsh or in special weather, it is difficult to always ensure that the concentrating mirror and the battery are facing the sun, so that the solar energy cannot be fully utilized, resulting in unstable output power of the solar battery and a significant reduction in conversion efficiency
