Embodiment Construction

[0034] First of all, the object of the present invention is to eliminate the above-mentioned disadvantages of silicon solar cells. Please refer to figure 1 , which shows a schematic structural view of a silicon solar cell with a ribbon-shaped polymer light-emitting conversion layer according to a preferred embodiment of the present invention. As shown in the figure, in order to achieve this goal, the silicon solar cell with a strip-shaped polymer light-emitting conversion layer of the present invention includes a single crystal silicon wafer 1 and a light-emitting conversion layer 2, which is bonded by a polymer The agent is filled with two kinds of phosphor powders, and it is characterized in that: the luminescence conversion layer 2 strongly absorbs short-wave and long-wave solar radiation and transmits it through a first phosphor powder 21 and a second phosphor powder 22 which have an optical connection. Converts to radiation in the orange-yellow, near-infrared and mid-inf...

Abstract

The invention relates to a silicon solar battery with a radiative transition layer polymer. The radiative transition layer polymer is formed by a polymerized binder filled with two kinds of fluorescent powder. The silicon solar battery is characterized in that the fluorescent powder in the radiative transition polymer strongly absorbs short wave and long wave solar radiation and converts the solar radiation into the radiation in the orange-yellow, near infrared and middle infrared spectrum zones.

Description

technical field [0001] The present invention relates to a monocrystalline silicon solar cell, in particular to a silicon solar cell with a band-shaped polymer luminescence conversion layer which uses a luminescence conversion layer to improve the performance of the solar cell. Background technique [0002] Solar cells are widely used in modern technologies, such as self-contained energy, communication equipment, computers, lighting sources, etc. Judging from the production status and development prospects of solar cells, it is a major new alternative energy source. Experts predict that in all countries in the world in the next few decades, the total power of solar cells will account for about 5% of the world's power resources. [0003] The main parameter of a solar cell is its effective coefficient of action, or efficiency. For monocrystalline silicon solar cells of the maximum diffusion type, this value is calculated by ζ = 24%. The efficiency value of solar cells produc...
