Abstract: At least some embodiments of the present disclosure provide a back sheet of a photovoltaic module, a photovoltaic modules and a manufacturing method thereof. The photovoltaic module includes: a plurality of battery cells arranged in an array and configured to receive light and generate power; and a thermally conductive layer in a mesh shape, including a skeleton section and a hollow section surrounded by the skeleton section. In the thickness direction of the photovoltaic module, at least a part of the skeleton section overlaps with a gap between adjacent battery cells, and the hollow section overlaps with the battery cell. The photovoltaic module can conduct the heat at the hot spot of the photovoltaic module in time while ensuring the power generation efficiency of the photovoltaic module, thus improving the stability of the photovoltaic module.
