New high-efficiency photovoltaic power generation concentrating device

Abstract

The invention discloses a novel high-efficiency photovoltaic power generation and condensation device. The device comprises a reflection cylinder, a first circular cell, a second circular cell, a pedestal, upper reflecting plates and low reflecting plates; and the reflection cylinder is cylindrical, the diameter of an opening portion of the cylinder is greater than that of the bottom of the cylinder, the first circular cell and the second circular cell are mounted in the bottom of the reflection cylinder and are fixedly connected in a back-to-back manner, the second circular cell is connected to the pedestal via a telescopic part, the two ends of the pedestal are provided with the lower reflecting plates corresponding to a light-receiving surface of the second circular cell respectively, the pedestal is connected to the upper reflecting plates via coiled pipes, and the upper reflecting plates are placed over the lower reflecting plates respectively and correspond to the lower reflecting plates. The novel high-efficiency photovoltaic power generation and condensation device is simple in structure, reasonable in design, easy to manufacture, and low in cost, can utilize solar energy fully, and enables that light reflected to a cell panel is uniform.

Description

technical field [0001] The invention belongs to the technical field of solar energy, in particular to a photovoltaic power generation concentrating device. Background technique [0002] Solar energy is a clean and pollution-free renewable energy, inexhaustible and inexhaustible. Fully exploiting solar energy can not only save the increasingly depleted conventional energy, alleviate the severe shortage of resources, but also reduce pollution and protect human beings. ecological environment for survival. Among many solar energy utilization technologies, solar photovoltaic power generation technology realizes the direct conversion of solar energy into electric energy, which is the most convenient way of utilization. It has the characteristics of safe and reliable operation, no fuel, no noise, no pollution, local utilization, It is easy to use and maintain, and the scale can be large or small, so it has been valued by countries all over the world. [0003] In recent years, the...

Problems solved by technology

Although my country has good solar energy resources and photovoltaic cell manufacturing capacity, the overall level of the solar photovoltaic industry is still far behind that of developed countries. First, the production of crystalline silicon raw materials used in solar cells depends on imports, and raw materials are in short supply. At present and for a long period of time in the future, there is little room for cost reduction. The second is that the application of solar photovoltaic systems is not yet widespread.

[0004] The existing structure of photovoltaic power concentrating devices has the following disadvantages: the Fresnel lens concentrator has uneven light concentrating; the large parabolic concentrator is difficult to manufacture; the V-shaped concentrator has a low concentrating factor; The four triangular mirrors of the
