[0030] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0031] Reference below Figure 1-Figure 3 A photovoltaic assembly 100 according to an embodiment of the present invention is described.

[0032] like Figure 1-Figure 3 As shown, according to an embodiment of the utility model, the photovoltaic module 100 includes: a crystalline silicon cell structure 10, a perovskite cell structure 20, a first unidirectional current element 30 and a second unidirectional current element 40. The perovskite cell structure 20 is connected in parallel with the crystalline silicon cell structure 10. The first unidirectional current element 30 is connected to the electrode of the crystalline silicon cell structure 10. The first unidirectional current element 30 allows current to flow from the crystalline silicon cell structure 10 to the first unidirectional current element 30. The second unidirectional current element 40 is connected to the electrode of the perovskite cell structure 20, so that they can be connected in parallel with the crystalline silicon cell structure 10 and the first unidirectional current element 30. The second unidirectional current element 40 allows current to flow from the perovskite cell structure 20 to the second unidirectional current element 40.

[0033] The electrodes connecting the crystalline silicon battery structure 10 and the first unidirectional current element 30 and the electrodes connecting the perovskite battery structure 20 and the second unidirectional current element 40 have the same polarity.

[0034] Specifically, to improve the efficiency of photovoltaic modules, traditional photovoltaic modules are formed by stacking a crystalline silicon cell structure and a perovskite cell structure. When the crystalline silicon cell structure and the perovskite cell structure are connected in series, the voltage of the perovskite cell structure differs greatly from that of the crystalline silicon cell structure, which may cause serious heating of the crystalline silicon cell structure and the perovskite cell structure. When the crystalline silicon cell structure and the perovskite cell structure are connected in parallel, circulation is easily generated between the crystalline silicon cell structure and the perovskite cell structure, thereby affecting the power generation efficiency of the photovoltaic module.

[0035] Therefore, the photovoltaic module 100 is mainly composed of a crystalline silicon cell structure 10, a perovskite cell structure 20, a first unidirectional current element 30 and a second unidirectional current element 40, wherein the perovskite cell structure 20 is connected in parallel with the crystalline silicon cell structure 10, which can avoid the problem of a large difference between the voltage of the perovskite cell structure 20 and the voltage of the crystalline silicon cell structure 10. Moreover, the crystalline silicon cell structure 10 is electrically connected to the first unidirectional current element 30, and the perovskite cell structure 20 is electrically connected to the second unidirectional current element 40. Finally, the currents in the first unidirectional current element 30 and the second unidirectional current element 40 will merge and flow together, so that the crystalline silicon cell structure 10 and the first unidirectional current element 30 can form a parallel circuit together with the perovskite cell structure 20 and the second unidirectional current element 40.

[0036] Furthermore, the first unidirectional current element 30 only allows current to flow from the crystalline silicon battery structure 10 to the first unidirectional current element 30, so that the first unidirectional current element 30 can prevent the current from flowing in the opposite direction thereof, and the second unidirectional current element 40 only allows current to flow from the perovskite battery structure 20 to the second unidirectional current element 40, so that the second unidirectional current element 40 can prevent the current from flowing in the opposite direction thereof, so that the current between the crystalline silicon battery structure 10 and the perovskite battery structure 20 cannot form a closed loop, thereby preventing the generation of a circulating current when the crystalline silicon battery structure 10 and the perovskite battery structure 20 are connected in parallel.

[0037] In addition, the polarity of the electrode connecting the crystalline silicon cell structure 10 to the first unidirectional current element 30 and the polarity of the electrode connecting the perovskite cell structure 20 to the second unidirectional current element 40 are the same, that is, when the first unidirectional current element 30 connected to the crystalline silicon cell structure 10 is connected to the positive electrode, correspondingly, the second unidirectional current element 40 connected to the perovskite cell structure 20 is also connected to the positive electrode. In this way, the current in the first unidirectional current element 30 and the current in the second unidirectional current element 40 converge at the positive electrode, thereby preventing the generation of circulating current.

[0038] Similarly, when the first unidirectional current element 30 connected to the crystalline silicon battery structure 10 is connected to the negative electrode, correspondingly, the second unidirectional current element 40 connected to the perovskite battery structure 20 is also connected to the negative electrode. In this way, the current in the first unidirectional current element 30 and the current in the second unidirectional current element 40 converge at the negative pole, thereby also preventing the generation of circulating current.

[0039] Furthermore, the crystalline silicon cell structure 10 is connected to the first unidirectional current element 30, and the perovskite cell structure 20 is connected to the second unidirectional current element 40. Since the voltage characteristics of the crystalline silicon cell structure 10 and the perovskite cell structure 20 are different, the first unidirectional current element 30 and the second unidirectional current element 40 can also play a role in voltage stabilization.

[0040] Therefore, the arrangement of the first unidirectional current element 30 and the second unidirectional current element 40 in the photovoltaic module 100 can prevent the generation of circulation between the crystalline silicon cell structure 10 and the perovskite cell structure 20, thereby avoiding the impact on the power generation efficiency and service life of the photovoltaic module 100.

[0044] The first packaging glue 50 fixes the perovskite cell structure 20 and the crystalline silicon cell structure 10, thereby preventing the perovskite cell structure 20 and the crystalline silicon cell structure 10 from moving or loosening under vibration or impact, thereby ensuring the stability and safety of the photovoltaic module 100. The first packaging glue 50 may be a TPO adhesive film.

[0045] The first packaging glue 50 has good thermal conductivity, which can help dissipate heat and ensure that the perovskite battery structure 20 and the crystalline silicon battery structure 10 are within a suitable operating temperature range. In addition, the first packaging glue 50 can also provide insulation to prevent a short circuit between the perovskite battery structure 20 and the crystalline silicon battery structure 10.

[0046] Furthermore, the first unidirectional current element 30 and the second unidirectional current element 40 are disposed in the first packaging glue 50 , which can also fix the positions of the first unidirectional current element 30 and the second unidirectional current element 40 and insulate the first unidirectional current element 30 and the second unidirectional current element 40 .

[0047] Furthermore, the tempered glass 80 is bonded to the bottom of the crystalline silicon cell structure 10 through the first packaging glue 50, and the tempered glass 80 can protect the crystalline silicon cell structure 10, thereby preventing external environmental factors such as wind, rain, dust, etc. from invading the inside of the photovoltaic module 100, thereby extending the service life of the photovoltaic module 100. Moreover, the tempered glass 80 has good light transmittance, allowing sunlight to directly irradiate the crystalline silicon cell structure 10 through the tempered glass 80, thereby improving the efficiency of light energy conversion.

[0048] According to some embodiments of the present invention, Figure 1 As shown, the first packaging glue 50 includes: a first glue layer 51, a second glue layer 52 and a third glue layer 53.
