Description
Technical Field
The invention belongs to the technical field of photovoltaic devices, and particularly relates to a perovskite solar cell with a hole transport layer, an electron transport layer and a perovskite layer which are all inorganic matters, and a preparation method thereof.
Background
The Miyasaka professor task group, university of Japanese tung shadow shore, early 2006 tried to use perovskite materials as light absorbing materials in dye-sensitized solar cells, they reported for the first time dye-sensitized perovskite solar cells with solar conversion efficiencies of 3-4% in 2009 (J.Am. Chem. Soc.,2009,131,6050). Next, the Nam-Gyu Park professor group of university of Korea improved energy conversion efficiency by nearly doubling (nanoscales, 2011,3,4088) by optimizing precursor solution concentration and annealing temperature, and perovskite solar cells really paid attention to their use of perovskite materials in all solid state structures like organic thin film solar cells, and improved energy conversion efficiency and stability (Sci.Rep., 2012,2,591). Because perovskite solar cells have significant advantages such as low raw material and manufacturing costs, and with the great investment in research efforts in related fields, the energy conversion efficiency of perovskite solar cells has been rapidly improved in recent years.
Such perovskite materials generally have ABX 3 Wherein A is a basic chemical formula + Typically organic cations (most commonly methylamine ions, CH 3 NH 3 + ,MA + ),B 2+ Is an inorganic cation (typically Pb 2+ ),X - As halogen anions (generally I - 、Cl - Or Br (Br) - :MAPb(I,Br,Cl) 3 ). The band gap of the perovskite material can be continuously regulated within 1.6 to 3.2 electron volts according to the types of halogen elements used. Using formamidine ion (CH (NH) 2 ) 2 + ,FA + ) Replacement MA + Or using Sn 2+ To replace Pb 2+ Or the band gap of the perovskite material can be further regulated by adopting methods such as mixed ions and the like, so that the sunlight absorption in a wider range is realized. Mesoporous structures are common because perovskite solar cells were originally evolved from dye sensitized solar cells. In this structure, in dense TiO 2 The selective electron transport layer is also provided with a layer made of TiO 2 A mesoporous layer composed of nano particles. On one hand, the mesoporous layer is used as a framework for depositing a perovskite filmOn the other hand, the electron diffusion distance can be reduced, and the electron collection efficiency is further improved. The mesoporous thickness used in the initial studies was about 500-600 nm, and the perovskite light absorbing material was completely infiltrated into the mesoporous framework. However, as research proceeds, it has been found that thinner mesoporous layers, on the order of 150-200 nanometers, can be used, while forming a continuous dense perovskite light absorbing layer thereon, resulting in better device performance. Because the diffusion length of electrons and holes in the perovskite material is long, the perovskite solar cell with higher efficiency can be obtained by using a planar structure after the mesoporous layer is completely removed, and compared with the mesoporous perovskite solar cell, the planar perovskite solar cell with simpler structure has obvious advantages in preparation structure, so that the planar perovskite solar cell is easier to realize commercialization finally.
The organic group used in the organic-inorganic hybrid perovskite solar cell at present leads to poor thermal stability and humidity stability of the final device, so that the use of inorganic cations to replace organic cations such as Methyl Ammonia (MA) or Formamidine (FA) is one of the main ways to improve the stability to obtain high efficiency, the use of cationic cesium (Cs) to replace organic cations to obtain an all-inorganic perovskite device, and the all-inorganic component CsPbI 2 Br has proper energy band (about 1.8 electron volts), is favorable for being integrated with the existing silicon-based solar cell to prepare a series cell, and can further obtain a high-efficiency cell device. The planar perovskite solar cell device structure that is common when the following includes planar (n-i-p) and planar inversion (p-i-n). The n-type electron transport material used in the planar structure is typically a metal oxide semiconductor material, the p-type hole transport material is typically an organic hole transport material, and the organic hole transport material used often needs to be doped with other substances due to its low mobility to obtain high energy conversion efficiency, which limits further commercial applications. The n-type electron transport materials used in the planar inversion structure are generally fullerenes and derivatives thereof, and the materials have the defects of high production cost, difficult purification and the like which restrict the mass production of the materials. Thus developing low-cost large-area stable all-inorganic calciumTitanium-ore solar cell devices and structures thereof are urgent.
