preparation example Construction

[0039] The invention discloses a method for preparing a thin film doped with anthracene organic compounds, which comprises the following steps:

[0040] The first step is to dissolve PCBM (fullerene derivatives). Under the conditions of 25 degrees Celsius room temperature and standard atmospheric pressure, dissolve PCBM powder in solvent U at a ratio of 5-40 mg / mL, and heat at 60-90 degrees Celsius for 1-6 hours, a solution of PCBM was obtained.

[0041] The second step is to prepare PCBM / ABMG mixed solution, add doped anthracene organic compound (ABMG) into the PCBM solution prepared in the first step, the mass ratio of ABMG:PCBM is 5~30:100, continue heating and stirring , ABMG completely dissolved to obtain the desired mixed solution doped with ABMG.

[0042] The third step is to prepare an electron transport layer film containing ABMG, and quickly and evenly smear the ABMG / PCBM mixed solution obtained in the second step on any substrate with a clean surface, and the thick...

Abstract

The invention relates to a preparation method of a doped anthracene organic compound thin film and application thereof. The novel conducting anthracene compound doping suitable for PCBM ([6,6]-phenyl-C61-butyric acid methyl ester) is introduced; ABMG has high conductivity, so that the mixed concentration of the ABMG in the PCBM can reach 10 percent to 15 percent, and the electron transmission performance of the PCBM is reduced; a formed PCBM film after the mixing with the ABMG is smoother; the coverage is more complete. The ABMG with high film forming performance and high conductivity is mixed in a conventional electron transmission layer material of PCBM; the electron transmission layer thin film with high flatness and complete coverage is obtained. Meanwhile, the thin film technology is applied onto perovskite solar batteries, so that the voltage of the solar battery, the filling factor and the conversion efficiency are all improved; the repeatability and the efficiency uniformity of multiple batches of solar batteries are also improved.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a preparation method and application of an anthracene organic compound thin film. Background technique [0002] A solar cell, also called a photovoltaic cell, is a photoelectric conversion device that converts solar energy into electrical energy by using the photovoltaic effect of semiconductors. According to the global installed capacity, solar power has become the third most important renewable energy after hydropower and wind power. At present, the commercial solar cell structure is realized around the P-N junction. The P-N junction can separate the electron-hole pairs caused by sunlight, and make the loads connected at both ends of the P-N junction work. In this way, solar energy is converted into electrical energy. The semiconductor materials used to make commercial solar cells include monocrystalline silicon, polycrystalline silicon, amorphous silicon, ...
