Embodiment Construction
[0041] Photovoltaic components are generally in the shape of plates or sheets, which basically extend in a plane and have a certain thickness. For convenience and clarity in describing the photovoltaic module according to the present disclosure, a direction perpendicular to a plane in which the photovoltaic module extends is defined as a "thickness direction". In the following description and in the appended claims, a feature being in "thermal communication" or "thermally connected" to another feature includes not only said one feature being in contact with said other feature in a heat transfer relationship, but also being in thermal communication with said other feature. An intermediate feature between the one feature and the other feature through which the heat of the one feature is transferred to the other feature, the heat transfer includes not only heat conduction but also heat radiation, heat convection, etc. There are various forms of heat transfer, and the present inve...

Abstract
At least some embodiments of the invention provide a manufacturing method of a photovoltaic module. The manufacturing method comprises the following steps: providing a transparent front plate; providing a back plate; providing a battery layer between the front plate and the back plate, wherein the battery layer comprise a plurality of battery cells and are arranged in an array and configured to receive light and generate power; and providing a thermally conductive layer on a surface of the back plate facing away from the cell layer. According to the method, the manufacturing cost of the heat conduction layer is reduced, and formation and later maintenance of the heat conduction layer are facilitated.
Description
technical field [0001] The present disclosure relates to a method for manufacturing a photovoltaic module. Background technique [0002] The hot spot effect of photovoltaic modules means that under certain conditions, the shaded solar cells in the series branch will be used as loads to consume the energy generated by other illuminated solar cells, and the shaded solar cells will be The phenomenon of fever. For large-sized photovoltaic modules, the hot spot temperature can reach more than 170 degrees. [0003] The hot spot effect of photovoltaic modules is very harmful. The shaded photovoltaic modules will consume part or all of the energy generated by the illuminated photovoltaic modules, reducing the output power. In severe cases, the solar cells will be permanently damaged, or even Burn out the battery unit. Therefore, reducing the hot spot temperature of large-size components is an urgent problem to be solved. [0004] At present, in order to reduce the temperature of...
