Description
Technical Field
The invention relates to the technical field of solar cells, in particular to a perovskite solar cell and a preparation method thereof.
Background
The lead-calcium-titanium halide ore has excellent photoelectric characteristics of long carrier diffusion length, adjustable band gap, high light absorption coefficient and the like, and is considered to be a promising photovoltaic material. Perovskite Solar Cells (PSCs) have been rapidly developed over the last decade. At present, the photoelectric conversion efficiency reaches 25.7%, and the photoelectric conversion performance can be compared with that of a crystalline silicon solar cell. However, the organic component (e.g., MA) in organic-inorganic hybrid PSCs+And FA+) Are very unstable and are easily volatilized or decomposed under high temperature, high humidity and oxygen attack, resulting in serious degradation or disappearance of the photoelectric properties of the PSCs. In addition, the preparation of organic-inorganic hybrid perovskites generally uses expensive poly [ bis (4-phenyl) (2, 4, 6-tri-phenyl) amine](PTAA), 2, 2 ', 7, 7' -tetrakis [ N, N-bis (4-methoxyphenyl) amino]The-9, 9' -spirobifluorene (spiro-OMeTAD) is used as a hole transport layer, which greatly increases the production cost of the organic-inorganic hybrid perovskite and further limits the large-scale application of the hybrid perovskite. Stability and high production costs are great challenges for future scaled applications of perovskite solar cells.
When inorganic cesium ions (Cs) are used+) When the organic cation is replaced, the perovskite material has higher intrinsic stability. The stability of the inorganic perovskite at high temperature is significantly improved due to the absence of volatile organic cations. Cesium-based all-inorganic halide perovskite CsPbX3(X ═ Cl, Br, I) has received extensive attention from researchers due to its excellent thermal stability and photovoltaic properties. Researchers have proved that perovskite materials can be used as photoelectric conversion materials and can also transmit carriers, so that a hole transport layer can be omitted, and a carbon-based all-inorganic perovskite solar cell without the hole transport layer is prepared. The perovskite solar cell has the advantages of simple structure, low preparation cost and short period. However, the stability and efficiency are still low because, on one hand, a large energy barrier exists between the perovskite layer and the carbon electrode, which hinders the rapid separation of holes; on the other hand, there is a phenomenon of poor contact between perovskite layers and carbon electrodes. Due to the fact thatHow to reduce the energy barrier between the perovskite layer and the electrode layer, improve the contact between the perovskite layer and the electrode layer and improve the stability of perovskite is a problem which needs to be solved urgently.
