Description

technical field [0001] This application relates to a high-efficiency solar cell module structure, especially a monocrystalline silicon or polycrystalline silicon solar cell module structure. Background technique [0002] The solar cell module mainly utilizes the photovoltaic cell layer capable of photoelectric effect to absorb light and convert the absorbed light energy into electrical energy, thereby achieving the purpose of generating electricity. Photovoltaic materials commonly used in photovoltaic cell layers include silicon-based materials such as monocrystalline silicon, polycrystalline silicon, and amorphous silicon, as well as thin films such as cadmium telluride, copper indium selenide, copper indium gallium selenide, and gallium arsenide. materials, and organic materials such as photosensitive dyes. Among these photovoltaic materials, the development of silicon materials is the most mature, and among silicon-based solar cells, monocrystalline silicon and polycryst...

AI Technical Summary

Problems solved by technology

However, in the prior art, the phosphor is placed on the upper side of the photovoltaic cell layer, so most of the converted light will diffuse toward the light-incoming surface and still cannot be utilized by the photovoltaic cell layer

In addition, the phosphor in the prior art is mixed in an additional light conversion layer, which also increases the time and cost of the process, and is prone to defects due to poor matching or adhesion between layers
