[0038] The invention provides a method for preparing a solar cell with an ultra-light structure, comprising the following steps:
[0039] Step 1: Select a solid material with a plane, a curved surface or a certain three-dimensional configuration as the substrate 0, and the geometric characteristics of the top surface of the substrate 0 are designed and selected according to the required configuration of the ultra-light structure solar cell.
[0040] Step 2: uniformly coating photosensitive photoresist on the surface of the substrate 0 by roll coating, scraping coating, spray coating or other methods. The photoresist can be a photocurable glue, or a glue that cures in the non-light-receiving regions but not in the light-receiving regions. The coating thickness of the photoresist is in the range of several nanometers to several millimeters.
[0041] Step 3: For the above-obtained substrate coated with photoresist, use a 3D printer to control the output characteristics of the ex...

[0049] Step 1: Select display glass as substrate 0;
[0050] Step 2: Evenly coat UV photosensitive glue on the substrate 0 by scraping method, and the thickness of the photosensitive glue is about 50 microns;
[0051] Step 3: Use the 3D printing system to control the uniform output of UV light from the UV light source, and uniformly expose and cure the entire photosensitive adhesive to form a cured adhesive 4; the unexposed and cured part is cleaned and removed with deionized water;
[0052] Step 4: Using the magnetron sputtering method, on the cured glue 4, evenly deposit the AZO transparent conductive film 1;
[0053] Step 5: Using PECVD (Plasma Assisted Chemical Vapor Deposition) method, on the AZO transparent conductive film, deposit P, I, N-type amorphous silicon films in sequence to form solar cell unit 2;
[0054] Step 6: Utilize the magnetron sputtering method to deposit a transparent conductive film 3 on the solar cell unit 2; note that the AZO transparent conductive...

Abstract
An ultralight-structure solar cell prepared on the basis of a 3D printing technology. The method comprises the following steps: step A, selecting a substrate, and then uniformly coating light-sensitive photoresist on the surface of the substrate; step B, determining an exposure region on the obtained substrate coated with the photoresist using a 3D printer, and curing the exposure region; step C, developing and fixing the photoresist, further curing and reinforcing the cured part, and cleaning to remove the part which is not cured; step D, depositing a thin film solar cell on the substrate prepared with a photoetching pattern; and step E, repeating the process of described step B to step D cyclically, and cleaning to remove all curing photoresist so as to obtain an ultralight-structure solar cell. On one hand, the cell has the characteristic of extremely low density of an ultralight material; on the other hand, the solar cell has the capability of converting solar energy to electric energy.
Description
technical field [0001] The invention belongs to the field of new materials and new energy, and relates to a thin-film solar cell and a preparation method thereof, in particular to an ultra-light structure solar cell prepared based on 3D printing technology. Background technique [0002] Ultra-light materials are a class of new materials that are undergoing rapid development. Ultra-light materials such as airgel and foam materials have been used in many fields such as sound insulation, heat insulation, waste water and gas, and dust removal. The operation of any device or equipment requires a power system first. Because the weight and size are much larger than ultra-light structure nano-devices or equipment, conventional electricity cannot be used as a power source to drive ultra-light-structure nano-devices to operate. [0003] 3D printing technology is used to prepare ultra-light materials with fine micro-nano three-dimensional structure, which makes the materials have ultr...
