[0036]

[0037] Preparation of 1-iodo-4-n-octyloxybenzene (1)

[0038] The mixture of 4-iodophenol (2.20g, 0.10mol), 1-bromooctane (19.00g, 0.10mol) and DMF (volume: 100ml) was in N 2 Joined under the protection of K 2 CO 3 (20.70 g, 150.00 mmol). The reactants were heated to 150°C for 48 hours and then cooled to room temperature. The reactant was extracted with chloroform, and purified by column chromatography (n-hexane) to obtain the product (10.00 g, 30%). 1 H NMR (400MHz, CDCl 3 ): δ7.54(m, 2H), 6.67(m, 2H), 3.91(t, 2H), 1.77(m, 2H), 1.44(m, 2H), 1.31(m, 8H), 0.90(t, 3H).

Description

technical field [0001] The invention relates to the field of perovskite solar cells, in particular to the development of a class of hole-transporting polymer materials based on a triphenylamine-anthracene structure and its application in perovskite solar cells. Background technique [0002] Since the solar cell was reported, it has gone through four development processes: the first generation is silicon-based solar cells represented by monocrystalline silicon and polycrystalline silicon; the second generation is based on cadmium telluride (CdTe) and copper indium gallium selenide (CdTe) CIGS) is a thin-film solar cell; the third generation is a solar cell represented by dye-sensitized (DSSC), organic (OPV) and quantum dots; the fourth generation is a new type of solar cell represented by a perovskite. As a new generation technology, perovskite solar cells are developing rapidly, and the photoelectric conversion efficiency has increased from 3.8% in 2009 to 9.7% in 2012 to ov...
