Abstract

The invention discloses a solar battery module capable of converting an optical internal total reflection wavelength. The solar battery module comprises a solar battery, a wavelength conversion layer which has a wavelength conversion function, and a cover panel; the side of the wavelength conversion layer is connected with the solar battery; and the cover panel is used for encapsulating the solar battery and the wavelength conversion layer. Therefore, a light source wavelength which has low photoelectric conversion efficiency for the solar battery or cannot be applied can be fully converted into an available light source wavelength, and the possibility that the solar battery receives the sunshine can be increased greatly to improve the light source utilization efficiency and achieve the best conversion efficiency.

Description

technical field [0001] The present invention relates to a solar cell module, in particular to a method for fully converting the wavelength of a light source in the sunlight that is originally low in photoelectric conversion efficiency or unusable for solar cells into a useful wavelength of light source, and greatly increases the probability of the solar cell receiving sunlight, so as to A solar cell module with excellent conversion efficiency is achieved. Background technique [0002] Due to the gradual shortage of energy, light energy technology, which belongs to green energy, is an important project for current energy research and development and application. Taking solar energy utilization as an example, the response efficiency of solar cells to the wavelength of light sources varies with different optoelectronic materials, such as Figure 1a As shown, it is a distribution diagram of the response efficiency characteristics of various photoelectric materials to the light so...
