The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of embodiments of the disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.

The embodiment of the present disclosure provides a photovoltaic module, as shown in fig. 1 to 4, including an upper cover plate 100, a battery cell 200, a lower cover plate 300, and a frame 500, where the upper cover plate 100, the battery cell 200, and the lower cover plate 300 are sequentially disposed from top to bottom to form a laminated part, and the laminated part and the frame 500 are fixedly connected or clamped, for example, a clamping groove is disposed on the frame 500, and the laminated part is clamped in the clamping groove. The upper cover plate 100 is provided with a raised strip portion 101 parallel to the edge of the upper cover plate 100, the raised strip portion 101 is positioned outside the joint of the frame 500 and the lamination, and the top surface of the raised strip portion 101 is higher than the top surface of the frame 500.

In the embodiment of the disclosure, the raised strip 101 parallel to the edge of the upper cover plate 100 is arranged on the upper cover plate 100, the raised strip 101 is higher than the frame 500, the photovoltaic module has a certain inclination angle when in use, and the raised strip 101 is located at the lower end, so that the raised strip 101 can shield the frame 500, rainwater flowing down from the upper cover plate 100 can flow out along the raised strip 101, thereby preventing the rainwater from flowing into the frame 500 and avoiding water accumulation at the frame 500 and the installation position of the lamination part. Simple structure, low in manufacturing cost, convenient to use prolongs photovoltaic module's life.

In an embodiment of the present disclosure, a side of the raised strip 101 facing away from the frame 500 is a slope structure. The inclined plane structure is arranged, so that rainwater can flow out along the same trend, and water accumulation or turning back can be avoided. Of course, both sides may be beveled. Wherein the slope of the ramp structure is less than 90 °, but is not limited thereto, and in some embodiments may be 80 °, 60 °, 45 °, 30 °, 20 °, or 10 °, and so on. The rainwater flows out more smoothly and the waterproof effect is better. For example, when the slope of the slope structure is less than 30 degrees, and the slope is smaller, the impact force of the received rainwater is smaller, the rainwater is not easy to wear, and the rainwater can flow out more quickly.

The cross-sectional shape of the raised strip portion 101 may be a trapezoid, for example, a right trapezoid, and for example, the raised strip portion 101 may also be a trapezoid with acute bottom angles, so that the raised strip portion 101 may be provided on the periphery of the upper cover plate 100, and when the photovoltaic module is installed and used, the photovoltaic module may be installed in any direction in an inclined manner, and rainwater may flow out along the raised strip portion 101. The side surfaces of the convex strip part 101 adjacent to the side frame 500 can be tightly abutted, when the convex strip part 101 shields the side frame 500, the phenomenon that a gap between the convex strip part 101 and the side frame 500 is too large can be avoided, dust enters the side frame 500, dust accumulation is avoided, the phenomenon that hot spots are caused due to mismatch of battery currents in the photovoltaic module is avoided, and potential safety hazards in actual operation of the photovoltaic module are reduced. Of course, in some embodiments, the protruding strip 101 may not be tightly abutted against the adjacent side surface of the frame 500, and may have a certain distance.

The raised strip portion 101 and the upper cover plate 100 are integrally formed, so that the manufacturing process is simple and quick, and assembly is not needed. The raised strip 101 and the upper cover plate 100 may be made of the same material, that is, the raised strip 101 may be a part of the upper cover plate 100, for example, when the upper cover plate 100 is a glass cover plate, the raised strip 101 may be a glass cover plate. The effective light-emitting area of the photovoltaic module cannot be reduced and the generated energy cannot be reduced due to the arrangement.

The raised strip portion 101 and the upper cover plate 100 may be manufactured separately and then connected together, for example, a bolt connection or an adhesive connection may be adopted, or a slot may be provided in the upper cover plate 100, and the raised strip portion 101 may be inserted into the slot. The adhesive member may be a hot melt adhesive, a pressure sensitive adhesive, or the like, but is not limited thereto.

In addition, a sealant film 400 is disposed in a gap between the upper cover plate 100, the battery cell 200 and the lower cover plate 300, and the three are bonded by the sealant film 400. The adhesive packaging film 400 may be EVA (ethylene vinyl acetate) or POE (polyolefin), but is not limited thereto. EVA normal atmospheric temperature is solid-state, can realize quick bonding after the heating melts, has high strength and high mobility, can produce higher intensity after the solidification, has improved photovoltaic module's intensity, shortens process time, improves the preparation efficiency.
