Embodiment Construction

[0024] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0025] Such as figure 1 As shown, a spectral downshifting color battery assembly includes an optical medium layer 2, a common medium layer 4, a solar battery array 1, welding wires, a back plate 5 and a junction box. In the area in front of the light-receiving surface of the battery sheet of the solar cell array 1, a spectrum down-transfer optical medium layer 1 is arranged, and the spectrum down-transfer optical medium layer 1 absorbs the short-wave band with poor spectral response of the battery and transfers it to the long-wave band with ideal spectral response of the battery. After the transfer, the photoelectric conver...

Abstract

The invention relates to a color battery assembly with a downward-transfer function for a spectrum, belonging to the technical field of solar photoelectric conversion. The color battery assembly comprises a solar battery array, the front area of the lighted surface of a battery slice of the solar battery array is provided with a spectrum downward-transfer optical medium layer; the spectrum downward-transfer optical medium layer absorbs a short wave range with poor battery spectrum response and transfers the short wave range with the poor battery spectrum response to a long wave range with ideal battery spectrum response and then carries out the photoelectric conversion through the battery slice; and the spectrum downward-transfer optical medium layer comprises a medium and semiconductor quantum dots, wherein the semiconductor quantum dots are uniformly dispersed in the medium, refer to nanoparticles of II-VI group compounds and have homogeneous or heterogeneous multi-layer structures. The color battery assembly is provided with common medium layers on the lighted surface and the backlight surface of the spectrum downward-transfer optical medium layer, enhances the response of the color battery assembly on short waves of a solar spectrum and effectively reduces the battery heat effect.

Description

technical field [0001] The invention relates to the technical field of photoelectric conversion of solar energy, in particular to a color battery assembly with a down-transfer function for spectrum. Background technique [0002] At present, the development of commercial photovoltaic modules has reached a very mature stage. It is difficult for people to make great progress in the efficiency of modules by improving various technical links of modules. For crystalline silicon components, the spectral response range is in the spectral region with a wavelength of 1100nm, but the best response wavelength is around 600nm. For the short-wave part of the solar spectrum, the response of solar cells is not ideal. These short-wave light is the main cause of the thermal effect of the battery. The strong thermal effect will seriously affect the stability of the efficiency of the battery and modules. Moreover, ultraviolet light in sunlight is The main cause of EVA aging in battery componen...
