A kind of mesoporous perovskite solar cell and preparation method thereof
Technical field
The invention belongs to Ca-Ti ore type thin-film solar cells cell art, particularly relate to a kind of mesoporous perovskite solar cell and preparation method thereof.
Background technology
Along with society constantly develops, energy problem has become one of most significant problems of the puzzlement mankind, even can say and arrive the stage of energy crisis.Traditional energy resources, such as coal, oil etc. are not only non-renewable, and its pollution on the environment is also day by day serious simultaneously, find the primary approach that Development of Novel regenerative resource is head it off.Solar energy as the representative of new forms of energy, always as the focus of scientific research field by people's extensive concern.Since monocrystaline silicon solar cell invention in 1954, utilize solar power generation to solve energy problem and given people very large hope.At present, widely used solar cell mainly contains silion cell, cadmium telluride cells and copper indium gallium selenide cell.But cost remains high, the life-span has much room for improvement etc., and shortcoming limits the further commercialization of this series of solar cell and widely uses, and can only be applied in some high-tech areas, as space satellite power supply etc.Therefore, research and develop novel solar cell with low cost and effectively can alleviate energy problem.
Liquid calcium titanium ore solar cell (Kojima, A. is reported from Miyasaka in 2009 etc.; Teshima, K.; Shirai, Y.; Miyasaka, T., OrganometalHalidePerovskitesasVisible-LightSensitizersfo rPhotovoltaicCells. journaloftheAmericanChemicalSociety 2009, 131(17), 6050-6051.) since perovskite solar cell start to receive extensive concern and develop rapidly.2014, along with the research of perovskite solar cell is reached the decisive stage, increasing scientific research sight was put in this field.Recently, the latest data display that American National Ministry of Energy regenerative resource laboratory (NREL) is issued, the peak efficiency of current perovskite solar cell reaches 20.1%, close to the photoelectric conversion efficiency of current commercialization silica-based solar cell, illustrate the broad prospect of application of perovskite battery.
Traditional mesoporous perovskite solar cell is primarily of conductive substrates, compacted zone, casing play, calcium titanium ore bed, hole transmission layer, form electrode.Perovskite solar cell can be thought and is derived from DSSC (DSC), and therefore traditional perovskite solar cell has followed the structure and material of DSSC mostly, adopts the porous TiO with special chemical and electrology characteristic 2as casing play.Casing play mainly serves the effect of support frame and transferring charge, also has and use insulator Al in research afterwards 2o 3as casing play, this casing play then just serves the effect of support frame, and transferring charge then carries out (Lee, M.M. by perovskite itself; Teuscher, J.; Miyasaka, T.; Murakami, T.N.; Snaith, H.J., EfficientHybridSolarCellsBasedonMeso-SuperstructuredOrga nometalHalidePerovskites. science 2012, 338(6107), 643-647.).
TiO 2as conventional casing play material, itself still also has some limitation.Such as its electron mobility is on the low side relative to similar inorganic oxide semiconductors such as ZnO, causes electronics at TiO 2the loss of layer inside is larger; Due to TiO 2internal flaw, cause its charge collection efficiency not high with the factor such as the contact defective tightness at perovskite interface, thus electric current is lower.These limitation all limit further developing of perovskite solar cell, therefore find the method overcoming these limitations, and the efficient stable perovskite solar cell that preparation has outstanding casing play is significant.
