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.

The present invention provides a fly ash-based environmentally-friendly hydrogel with a high water retention for preventing and controlling spontaneous combustion of coal in a mine and a preparation method thereof. The hydrogel includes the following raw materials in the following weight percentages: 10% to 30% of a gel-forming material A, 20% to 45% of a crosslinking material B, and water as a balance, where the gel-forming material A is prepared by physical blending of a biodegradable superabsorbent resin, anionic polyacrylamide, a sesbania gum, and fly ash in a weight ratio of (1-3):(0.5-1):(0.5-1):(95-98); and the crosslinking material B is prepared by subjecting zeolite, expandable graphite, and an aluminum citrate complex in a weight ratio of (60-78):(20-36):(2-4) to mixing, dispersing, adsorbing, and freeze-drying. The gel-forming material A is added to water and stirred at room temperature until homogeneous, and then the crosslinking material B is added and stirred until homogeneous to obtain the hydrogel. In the present disclosure, the environmentally-friendly hydrogel with the high water retention is prepared with wastes such as fly ash as a base material, and can be prepared simply with a low cost. In addition, the hydrogel has the advantages of degradability, strong water retention, and a controllable gelation time. The hydrogel can cover and wet a coal body for a long time, and prevent and control the spontaneous combustion of coal in a mine for a prolonged time.
