Problems solved by technology

[0002] Solar photovoltaic modules generally glue the glass layer, the front layer of adhesive film, several battery components arranged in spaced arrays, the rear layer of adhesive film, and the photovoltaic backplane through vacuum and high temperature. The panels have absorption and reflection effects on sunlight, which reduces the conversion efficiency of photovoltaic modules
And because the battery components are arranged at intervals, when the solar photovoltaic modules work facing the sun, the light incident on the battery components can be used, but the light incident on the gap between the battery components is not used, thereby reducing the photon utilization rate of the photovoltaic components and output power

Abstract

The invention discloses a solar photovoltaic module which includes a photovoltaic glass layer, a front coating layer, a photovoltaic battery component layer, a rear coating layer and a bottom plate layer. The photovoltaic battery component layer is composed of multiple battery components connected in series and spliced together. A reflective medium is arranged on the photovoltaic glass layer rightabove the connection gap between every two adjacent photovoltaic battery components. As the reflective medium is vertically arranged above the gaps between the photovoltaic battery components, more photons will shoot into the photovoltaic battery components from the photovoltaic glass layer, and part of the photons shooting into the reflective part of the photovoltaic glass layer will be reflected to the adjacent photovoltaic glass and then shoot into the battery components because of the reflection function of the reflective medium. Therefore, the utilization rate of photons is greatly improved, and the output power of the whole photovoltaic module is improved.
