Embodiment 1

[0019] Such as figure 1 As shown, a mask plate used for electrode evaporation of solid-state dye-sensitized solar cells includes a first area and a second area, and the first area and the second area include an evaporation area and a non-evaporation area. area, 100 is the first vapor deposition rectangular area, 101 is a fixed small hole, and there are rib support members between the small holes, which shortens the distance between the cathode and the transition area, 102 is the gap between the first area and the second area, and 103 is The evaporation rectangular area in the second area, 104 is a transition area.

[0020] There are 2-3 fixed holes between the slits, 1-4 fixed holes on the edge of the first zone and the second zone, and the distance between the fixed holes and the rectangular area of ​​the second zone is 2mm-3mm. The thickness of the plate body is about 300-500μm, the distance between each column of small holes in the slit is 3mm-8mm, the length of the ribbed...

Abstract

The invention relates to a metal mask plate for solid-state dye sensitized solar cell electrode evaporation. The metal mask plate comprises a first zone and a second zone, and both the first and second zones are evaporation zones and are separated; each of two ends of the first zone is provided with a small hole, four parallel slots are formed in the second zone, each slot is provided with a list of small holes in the middle, and a rib support component is arranged between every two small neighboring holes on each list. By the metal mask plate for evaporation, tension of clearance of metal can be balanced, balance effect is better, and electrode series are avoided by separation of the first zone from the second zone; moreover, less zones are occupied according to the design, multiple electrodes can be evaporated at the same time, and testing time for solid-state batteries is saved; the manufacturing process of the mask plate can be simplified, cost for the mask plate is lowered, and the metal mask plate can be reused.

Description

technical field [0001] The invention belongs to the field of solar energy equipment, and in particular relates to a metal mask plate used for electrode evaporation of solid-state dye-sensitized solar cells. Background technique [0002] Thin-film solar cells using perovskite-type organic lead-iodide compounds as light-absorbing materials are new types of solar cells after dye-sensitized and quantum-dot sensitized. Perovskite organolead-iodide compounds have unique photoelectric properties, and all solid-state thin-film batteries based on hole transport materials have shown excellent photoelectric conversion efficiencies. [0003] Thin-film batteries require corresponding electrode support due to their special structure, so evaporation is required, and a mask plate is required to shield the non-evaporation area during the evaporation process. However, due to the short distance between the two electrodes, it is easy to cause deformation of the mask plate, and at the same time...
