Description
Technical field
The present invention relates to perovskite technical field of solar batteries, more particularly to a kind of solar cell.
Background technology
In recent years, organic inorganic hybridization perovskite solar cell shows excellent photoelectric properties and huge potentiality.
With the development of perovskite solar cell technology, the battery device photoelectric transformation efficiency based on this light absorbent is up to 19.3%.
Based on CH3NH3PbI3Solar cell worldwide received much concern due to the efficiency lifted rapidly.At present
The structure that solar cell is reported at present mainly FTO/TiO2/CH3NH3PbI3/ spiro-OMeTAD/Au, its battery efficiency shows
Reach 20.1%；But this structure, is primarily present following shortcoming：TiO2The preparation of compacted zone needs to enter at a high temperature of 450 DEG C
Row sintering, CH3NH3PbI3Layer preparation be also required to slowly crystallize under conditions of heating, these heating processes be all unfavorable for by
The CH of excellent performance3NH3PbI3Materials application is in the substrate that can not much heat, such as macromolecule membrane.
Therefore, research and development are a kind of can be by the CH of excellent performance3NH3PbI3Material rapid crystallization life under conditions of without heating
Into, and perovskite battery preparation temperature can be greatly lowered
Solar cell is necessary.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of can be by the CH of excellent performance3NH3PbI3Material is without heating
Under conditions of rapid crystallization generation, and the solar cell of perovskite battery preparation temperature can be greatly lowered.
In order to solve the above technical problems, the technical scheme is that：A kind of solar cell, including glass substrate and according to
The secondary compacted zone being laminated on the substrate, calcium titanium ore bed, hole transmission layer and metal electrode layer；Its innovative point is：
It is 10-15 ohm, fluorine doped tin oxide glass of the transmitance in 80-85% that the glass substrate, which uses square resistance,；
The compacted zone is zinc oxide compacted zone, and the thickness of its compacted zone is 30nm；
The calcium titanium ore bed is formed by methylamine lead iodine, and the thickness of its calcium titanium ore bed is 200nm；
The hole transmission layer is formed using Spiro-OMeTAD HTM solution drop coatings, and the thickness of its hole transmission layer is 100nm；
The metal electrode layer uses silver, and the thickness of its metal electrode layer is 120nm.
The advantage of the invention is that：
The present invention is by FTO/TiO2/CH3NH3PbI3/ spiro-OMeTAD/Au original structures are improved, and are changed to FTO/
ZnO/CH3NH3PbI3/ spiro-OMeTAD/Ag structures, the perovskite solar cell of this structure significantly reduces calcium
Temperature prepared by titanium ore battery, while also causing CH3NH3PbI3Material rapid crystallization generation under conditions of without heating, and then
Significantly improve the photoelectric conversion rate and stability of battery.
