Embodiment 1

[0043] This embodiment provides a method for preparing a solar cell, and the specific preparation steps are:

[0044] First, rare earth element Yb-doped CsPbCl1.5Br1.5 perovskite quantum dots were prepared by hot injection method, the specific method is as follows: Weigh 0.8g Cs 2 CO 3 , add 30ml octadecene (ODE) and 2.5ml oleic acid, in N 2 Under the protection of the atmosphere, heat up to 150°C until completely dissolved to synthesize cesium oleate; weigh PbBr 2 (0.5 mmol), YbCl 3 (0.4mmol), add 1ml oleylamine, 1ml oleic acid, 10ml ODE, in N 2 Under atmosphere protection, raise the temperature to 160°C until the precursor is completely dissolved, then raise the temperature to 200°C and inject 1ml of the prepared cesium oleate solution, react for 10s, and cool in ice water. Yb can be obtained after centrifugal purification 3+ Perovskite quantum dots doped with rare earth elements. Next, configure the UV screen printing ink of CsPbCl1.5Br1.5:Yb (5%) according to the mas...

Embodiment 2

[0053] This embodiment provides a method for preparing a solar cell, and the specific preparation steps are:

[0054] Get the CsPbCl that configures in embodiment 1 1.5 Br 1.5 : UV screen printing ink of Yb (5%) perovskite quantum dots, use 200 mesh, polyester screen with a wire diameter of 40 μm, use an 80-degree scraper to screen-print the pane pattern, and obtain a silver-white coating with a thickness of 52 μm ,Such as image 3 As shown, the dark lines are the silver-white Quantum Cut coating, and the white parts are blank. Steps such as UV light curing, encapsulation, lamination, and testing are exactly the same as those in Example 1. The coating area accounts for about 20% of the entire battery area. Due to the reduction of the quantum tailoring coating area, the battery efficiency drops to 19.5%. The adhesion is good, and its peel strength is 123.0N / cm.

Embodiment 3

[0056] This embodiment provides a method for preparing a solar cell, and the specific preparation steps are:

[0057] Get the CsPbCl that configures in embodiment 1 1.5 Br 1.5 : The UV screen printing ink of Yb (5%) perovskite quantum dots, with 200 orders, the polyester screen of silk diameter 40 μ m, with 80 degree scraper, screen printing pattern, obtains the silver-white coating that thickness is 59 μ m, Such as Figure 4 As shown, the dark part represents the silver-white quantum tailoring coating, and the white part represents the blank. Steps such as UV light curing, encapsulation, lamination, and testing are exactly the same as those in Example 1. The coating area accounts for about 80% of the entire battery area. Due to the increase in quantum tailoring coating area, the battery efficiency is increased to 21.9%, but the adhesion has been greatly reduced, and its peel strength is 88.0N / cm.

Abstract

The invention belongs to the technical field of solar cell preparation, and particularly relates to a preparation method of a quantum cutting coating, a solar cell, an assembly and a preparation method. The method comprises the following steps: mixing a down-conversion material with organic glue, coating the surface of a glass substrate with the mixture, and curing to obtain the quantum cutting coating. The patterned quantum cutting coating is prepared on the glass substrate creatively by adopting an organic glue pre-curing mode, so that the quantum cutting coating does not move relative to a glue film in the subsequent laminating process, the uniformity of the film layer is improved, and the problems that in the prior art, due to the fact that the quantum cutting coating is prepared by adopting an organic solvent, the coating is not uniform, and the quality of the film layer is poor are solved. And the conversion efficiency of the assembly is influenced.

Description

technical field [0001] The invention belongs to the technical field of solar cell preparation, and in particular relates to a preparation method of a quantum tailoring coating, a solar cell, an assembly and a preparation method. Background technique [0002] Building Integrated Photovoltaics (BIPV) is a new concept of applying solar power generation. Simply put, it is to install solar photovoltaic power generation components on the outer surface of the building envelope, which can be used as building materials and generate electricity. It is truly photovoltaic The perfect combination of components and construction. If BIPV is applied on a large scale, the market will enter the trillion level, which will promote energy saving and consumption reduction, low carbon emission reduction, and more effective development and application of sustainable clean energy. However, the current hot market has put forward higher requirements for the performance and aesthetics of BIPV, so it i...
