A photoelectric energy conversion module

Abstract

The invention relates to a photoelectric energy conversion module. The upper end of the housing is open to communicate with a cylindrical cavity made in the housing. A protrusion is formed on the inner wall of the housing at the lower end of the cavity. The upper end surface of the protrusion is connected to the inner wall of the housing. The optical device is embedded between the optical device fixing rings installed in the cavity, the upper end opening of the housing above the optical device is installed with a flange joint, and the bottom surface of the cavity below the optical device is installed with a photocell, and the photocell is composed of multiple The sub-batteries connected in series are spliced, and each sub-battery is fan-shaped or triangular. The overall outer edge of the photovoltaic cells after splicing is circular or polygonal. The first sub-battery and the last sub-battery are respectively connected to the positive terminal embedded in the bottom of the shell. and negative terminal. In the present invention, various structures cooperate with each other to realize a new type of module with the advantages of large optical path diameter, large optical path length, uniform light intensity, high output voltage and power, and stable operation. It can be used in different equipment in different environments for a long time. Stable job.

Description

technical field [0001] The invention belongs to the technical field of photoelectric energy conversion structure improvement, in particular to a photoelectric energy conversion module. Background technique [0002] The photoelectric energy conversion module is a new type of energy transmission. It transmits the laser energy emitted by the semiconductor laser source to the module through the optical fiber, and then converts the laser energy into electrical energy by the photoelectric cell to provide the required electrical energy for the terminal equipment. It has the characteristics of good insulation and low loss, and can transmit energy to a distance of hundreds of meters or even thousands of meters. At the same time, because the laser is transmitted in the optical fiber, it is completely insensitive to high temperature, low temperature, radiation and electromagnetic interference. The module It can be used in the power supply of isolated circuit breakers in the electric po...

Problems solved by technology

[0003] The existing modules have the following disadvantages: 1. The photovoltaic cell adopts a micro-cell structure, which requires an epitaxial PN reverse junction structure cell on a semiconductor substrate, and then produces a plurality of fan-shaped sub-cells through multi-step photolithography and overlay engraving. The output voltage of the battery is constant and cannot be increased or decreased; 2. The distance between the laser and the photocell has strict requirements to ensure that the laser can illuminate the photocell as much as possible, and the error requirements for the shell are extremely high; 3. The output power of the photocell Constant, but when it needs to be adjusted, the photocell can only be replaced as a whole, which is very inconvenient to use; 4. The area of ​​the TO base is small and the heat dissipation effect is poor, which is not conducive to long-term stable operation
