Description

A kind of Ca-Ti ore type opto-electronic conversion composite sol and preparation method thereof
Technical field
The present invention relates to a kind of Ca-Ti ore type opto-electronic conversion composite sol and preparation method thereof, especially with two acyls Imines and methylamine are mixed with Ca-Ti ore type opto-electronic conversion composite sol, with adjust Ca-Ti ore type light absorbing material band gap and Improve photoelectric transformation efficiency, belong to new forms of energy and field of new.
Technical background
Perovskite is referred to as too based on the solaode of organic metal halogenide perovskite structure light absorbing material preparation Positive electricity pond, more than 20%, future is expected to reach 50% its photoelectric transformation efficiency at present.Perovskite solar cell is typically by saturating Bright electro-conductive glass, compacted zone, perovskite light absorbing zone, hole transmission layer, metal back electrode five part composition.Perovskite light absorbs The thickness of layer is generally 200-600nm, and Main Function is to absorb sunlight and produce electron-hole pair, and can high efficiency of transmission electricity Son-hole pair.
Perovskite light absorbing material Typical molecular formula is AMX3, wherein, A represents ammonium ion or the metal ion of monovalence, M Represent metal cation, X represents halide anion.Research to metal cation and halide anion is compared both at home and abroad at present Thoroughly, but to the composition of the ammonium ion of monovalence, structurally and functionally Mechanism Study is little and unclear.
At present both at home and abroad to Ca-Ti ore type light absorbing material iodate methylamine lead（CH3NH3PbI3）Research relatively more, it be by A kind of inorganic-organic double salt of iodine methylamine and lead iodide reaction generation or coordination compound, it is also a kind of Semiconductor absorption Material, its band gap is about 1.5eV, can fully absorb the visible ray of wavelength 400-800nm, has that absorbing properties are good, system Characteristic standby simple and that photoelectric transformation efficiency is high.Its mainly deficiency be：（1）Temperature tolerance bad it is desirable to the heat treatment of light absorbing zone Temperature is less than 150 DEG C, and the additive in light absorbing zone preparation can not decompose completely at such a temperature；（2）Environmental stability is poor, It is easily that in air, dampness, ultraviolet light or catalyst decompose；（3）Absorb optical wavelength range and be confined to visible region, to ultraviolet light Hardly pick up with infrared light；（4）Filming performance is bad, easily forms loose thick crystalline solid it is difficult to large area uniformly applies Cloth.
Improve Ca-Ti ore type light absorbing material performance, can start with from the composition design of Ca-Ti ore type light absorbing material.For example, Perovskite structure light absorbing material is prepared using the primary amine of C1-C4, carbonamidine or its mixture by the biological institute in Chinese Academy of Sciences Qingdao, and acquisition is good Good photoelectric transformation efficiency；Xiamen University's patent of invention CN106058060 (2016-10-25) is open to adopt methylamine and carbonamidine to mix Perovskite structure light absorbing material thin film is prepared in conjunction；Wuhan University of Technology's patent of invention CN105742502 (2016-07-06) is public Exploitation iodobenzene ethamine, Tin diiodide. and lead iodide are mixed with band gap adjustable perovskite structure light absorbing material；Central China section Skill university patent of invention CN103762344 (2014-04-30) is open to be mixed with calcium using aminobutyric acid amphiphatic molecule and methylamine Perovskite like structure light absorbing material；United States Patent (USP) US20150249170 (2015-09-03) disclosure long-chain organic amine prepares calcium titanium Ore deposit structure light absorbing material, but the details of long-chain organic amine is not disclosed；United States Patent (USP) US20150200377 (2015- 07-16) open a series of primary, secondary, uncles, quaternary ammonium compound are prepared perovskite structure light absorbing material, but are not provided amine The embodiment of compound；Chinese patent CN103554171 (2014-02-05) is open to adopt 1- aminopyridine azomethine and chlorination Lead coordinates as potential dielectric material；The open 1- ethyl-3-methylimidazole of Chinese patent CN102337593 (2012-02-01) Tribromide iodine perovskite structure light absorbing material preparation method.
Improve perovskite light absorping film performance it is also possible to start with from perovskite light absorbing material structure.For example, Singapore south Foreign Polytechnics patent of invention WO2016126211 (2016-08-11) discloses perovskite light absorbing material and nanoclay grain Son forms colloidal sol in organic solvent, and nanoparticle as crystal seed, improves the microstructure of perovskite light absorbing material and becomes Film properties；Tianjin Professional College patent of invention CN105789339 (2016-07-20) open by perovskite light absorbing material with Nano-silicon dioxide particle forms colloidal sol in organic solvent, nanoparticle as light absorbing material crystal seed and framework material, one Step obtains the light absorbing zone of smooth even；Nankai University's patent of invention CN104218109 (2014-12-17) discloses polyethylene Ketopyrrolidine is mixed with perovskite light absorbing material, improves microstructure and the filming performance of perovskite light absorbing material, greatly Big raising photoelectric transformation efficiency.
Although perovskite photoelectric conversion efficiency of the solar battery data constantly refreshes, Ca-Ti ore type light in terms of research angle In absorbing material, organic cation kind is few and potential of innovation is big；Perovskite light absorbing material filming performance in terms of application angle Difference, is not met by the coating of large area perovskite solar cell light absorption layer through engineering approaches and requires.Heliotechnics exploitation and industry The three big key elements changed are photoelectric transformation efficiency, production cost and battery performance stability, market demand photoelectric transformation efficiency Higher perovskite solar cell photoelectric conversion material.
