example 1

[0049] A formal structure perovskite solar cell is prepared, which includes a transparent conductive substrate, a conductive sublayer, a photoelectric conversion layer and a hole-conducting layer sequentially coated on the transparent conductive substrate. Correspondingly, the present invention includes three push-coating System, according to the printing order, the corresponding coating die number 1, 2, 3.

[0050] The working process of the present invention is as follows: before printing, open the air inlet valve to introduce protective gas into the shell, so as to realize the complete isolation of the printing process from the outside world, and protect the perovskite solar cell from other environmental factors during the printing process; The clean 10cm×10cm transparent conductive substrate is placed on the vacuum adsorption platform, and the movement speed of the vacuum adsorption platform on the moving platform is controlled to be 1~100mm / sec, so that it passes through t...

example 2

[0054] A trans-structured perovskite solar cell is prepared, which comprises a transparent conductive substrate, a hole-conducting layer, a photoelectric conversion layer, a conductive sublayer and an electrode material layer sequentially coated on the transparent conductive substrate. Correspondingly, the present invention includes 4 A bolus coating system, according to the printing order, the corresponding coating die number 1, 2, 3, 4.

[0055] The working process of the present invention is as follows: place the cleaned 10cm×10cm transparent conductive substrate on the vacuum adsorption platform, control the movement speed of the vacuum adsorption platform at 1-100mm / sec, make it pass through the coating die No. 1 at a uniform speed, adjust the The ink extrusion volume of No. 1 coating die is 1-100ul / sec, and the total printing ink volume is controlled to be 1-100ul. Through the above control, the wet film thickness of 1-3 microns can be printed on the transparent conductiv...

example 3

[0060] By replacing the transparent conductive substrate in Example 1 with a flexible transparent conductive substrate (flexible glass substrate or flexible plastic substrate), the printing of flexible formal perovskite solar cells can be realized.

Description

technical field [0001] The invention relates to a solar cell printing machine, in particular to a perovskite solar cell printing machine. Background technique [0002] Solar cells are a kind of free clean energy, which has long been monopolized by solar cell technology represented by crystalline silicon. However, the production of crystalline silicon solar cells is not cheap and not clean. The third-generation solar cells represented by perovskite solar cells can be produced by full printing. The thickness of each functional layer in this solar cell is only tens to hundreds of nanometers, and multiple printings are required to complete the solar cell device. Therefore, it is necessary to design a set of printers capable of printing a variety of high-quality ultra-thin films to achieve this purpose. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a perovskite solar cell printing machine, which can complete the printing of all function...
