Embodiment Construction

[0019] Such as Figure 4 Shown is a TCO glass structure diagram according to an embodiment of the solar module of the present invention, which sequentially includes a scattering film 45, a glass layer 40, a front transparent conductive oxide layer 41, a semiconductor layer 42, and a rear conductive layer from the light incident surface 43 and encapsulation material 44. The front transparent conductive oxide layer 41 is used as a front electrode, the rear conductive layer 43 is used as a back electrode, and the semiconductor layer 42 is a light absorbing layer.

[0020] Wherein, the scattering film 45 includes an adhesive (not shown), a solvent (not shown) and nanoparticles 451 , and the diameter of the nanoparticles 451 is smaller than or equal to the wavelength of the reaction light.

[0021] The nanoparticles 451 can scatter the reaction light, increase the transmission path of the reaction light in the TCO glass, increase the probability of the reaction light being absorbe...

Abstract

The invention provides a solar module and a manufacturing method thereof. The solar module successively consists of a scattering film, glass, a front transparent conductive oxide layer, a semiconductor layer, a back conductive layer and a packaging material from a light incident surface. The scattering film comprises an adhesive, a solvent and nano particles. The refractive index of the scattering film is greater than the refractive index of air and less than the refractive index of glass. By using the middle refractive index between the refractive index of air and the refractive index of glass to reduce reflection, and by using the scattering film comprising the nano particles to increase the glass haze, the light transmission quantity into the film solar cell semiconductor layer is increased, and the light absorption quantity of the film solar cell semiconductor layer is further increased.

Description

technical field [0001] The invention relates to a thin-film solar battery, in particular to a solar module and a manufacturing method thereof. Background technique [0002] A thin-film solar cell is a battery formed by depositing a semiconductor thin film on a carrier. Under the condition of light, the semiconductor thin film converts light energy into electrical energy, and outputs the electrical energy through the front electrode and the back electrode. Transparent conductive oxide (TCO) glass is widely used in the fields of solar cell front electrode, flat liquid crystal display (LCD), thermal mirror and glass curtain wall due to its characteristics of transparency, conductivity and selectivity to light waves. [0003] Since light will be reflected at two different media, the greater the difference in the refractive index of the two media, the greater the reflection. Therefore, if the TCO glass has the function of anti-reflection, most of the light can enter the semicondu...
