Solar battery chip protection structure

Abstract

The present invention provides a solar cell chip protecting structure, the top of the battery cell is arranged with a beam condenser, wherein the position corresponding to the magnitude of the cell chip on the beam condenser is arranged with a light-permeating area, the outer margin of the light-permeating area of the beam condenser is a light reflecting area; and the light-permeating area is obscured glass or toroidal lens. When the magnitude of the light-permeating area is just corresponding to the magnitude of the chip, the chip can effectively collect the sun ray; additionally the collected light which excepts the solar chip and needs not be utilized is reflected by the reflecting area or absorbed for avoiding the irradiating to the PCB board and causing the temperature raising and leading to the melting or rupture of the PCB board thereby effectively prolonging the service lifetime of the solar battery; and the light-permeating area is executed with matte surface treatment or is arranged to an optical toroidal lens can lead to that the light irradiating into the chip is rearranged through the scattered reflection or reflection / refraction of the toroidal lens, for uniformly arranging the light emitting to the chip, increasing the filling factor of the solar cell chip, overcoming the disadvantage of the light-focusing solar battery, sufficiently exerting the predominance and greatly increasing the effective utilization rate of the solar cell.

Description

technical field [0001] The invention belongs to the field of solar energy, in particular to a solar cell chip protection structure. Background technique [0002] A solar cell is a device that directly converts solar energy into electrical energy due to the photovoltaic effect. When the sun shines on the solar cell, it will convert the sun's light energy into electrical energy and generate electric current. When multiple solar cells are connected in series or in parallel, it can become a solar cell matrix with large output power. Solar cells are a promising new energy source with three advantages of durability, cleanliness and flexibility. Solar cells have a long lifespan. As long as sunlight exists, solar cells can be used for a long time with one investment; compared with thermal power generation and nuclear power generation, solar energy itself is an environmentally friendly green energy that will not cause environmental pollution; solar cells can be large, medium and sm...

Problems solved by technology

[0003] With the further widespread application of solar energy, high light intensity in the field of solar energy can improve the fill factor of solar cells and effectively reduce costs, but if the light is too strong, the temperature rise will melt or break the PCB board outside the chip, so scientific and reasonable treatment "Concentration remaining outside the chip" is very important. This point is one of the key issues in the application of the entire battery, which directly determines the life of the solar concentrating system; another key issue is that the intensity of light received on the same solar cell chip is different. Uniformity will reduce its fill factor, thereby affecting battery efficiency and life, and ultimately leading to an increase in cost

Therefore, it is very important to deal with the "concentration remaining outside the solar chip" and "uniformity" in the concentrating light system in the application of the entire solar concentrating cell. At present, no solution to the above problems has been proposed in the market.
