Embodiment Construction

[0019] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] The invention provides a solar panel for laser energy transmission, such as figure 1 As shown, it includes N solar cell units (N≥2), substrates and electrodes. Among them, the number of solar cells in each solar cell unit is the same, and it is composed of 8 to 50 rectangular solar cells in series. N solar cell units are spliced ​​on the substrate from the inside to the outside in a circumferential direction, and spliced ​​in circles to form an approximately circular shape. . Among them, first calculate the number of rectangular solar cells required by the solar cell unit 1 according to the voltage required by the load and the voltage of each rectangular solar cell; The center of the laser spot is spliced ​​in a circle from the inside to the outside to form an approximate circle; the rectangular solar cells of the solar cell unit 2 are connected i...

Abstract

The invention discloses a solar cell panel and a photovoltaic conversion device used for laser energy transmission. By using the solar cell panel and the photovoltaic conversion device, the requirement for the laser wireless energy transmission photovoltaic conversion application can be met, and efficient and high-power electric energy output is achieved. The character of laser spot energy distribution is used, solar cell units are arranged in laser spots in an approximately round shape, so that the illumination intensity difference among the surfaces of all solar cells in the solar cell units is minimum, the influence on output power of the solar cell units due to uneven laser spot energy distribution is reduced, and output power of a solar cell panel is improved; meanwhile, diodes are adopted for an energy managing unit for protecting the solar cell units connected into in parallel so that the hot spot effect can be restrained; a maximum power tracking unit is adopted, so that it is ensured that the solar cell panel always maintains maximum power output when outside laser illumination intensity, temperature and load resistance change.

Description

technical field [0001] The invention relates to the technical field of wireless energy transmission, in particular to a solar cell panel and a photoelectric conversion device for laser energy transmission. Background technique [0002] The traditional solar power generation system uses sunlight as energy, which has the characteristics of uniform light intensity distribution, and the size of the solar panel is not restricted by the size of the light spot. For laser wireless energy transmission, due to the uneven energy distribution of the laser spot, the shape of the solar panel is constrained by the shape of the laser spot. The traditional solar panel design cannot meet the requirements of the photoelectric conversion application of laser wireless energy transmission. Contents of the invention [0003] In view of this, the present invention provides a solar cell panel and a photoelectric conversion device for laser energy transmission, which can meet the requirements of ph...
