Embodiment 1
[0073] Preparation of 3,4,5-trimethoxy-1-[(3-nitro-4-methoxyphenyl)thio]benzene (ZLM-6)
[0074]
[0075] Dissolve O-ethyl-S-(3,4,5-trimethoxyphenyl)dithiocarbonate ZLM-1 (2.42g) in THF (32mL), slowly add LiAlH 4 (1.3g), refluxed for 1h, cooled to room temperature, adjusted to pH=5 with 10% HCl, then extracted 20mL×4 with EA, combined the organic phases, dried with anhydroussodium sulfate for 1h, and then filtered with suction to obtain the filtrate, which was spun After removing the solvent, a yellow oil was obtained. Under nitrogen protection, first add potassiumcarbonate (1.16g, 8.40mmol, 2.0eq), CuI (400mg, 2.10mmol, 0.5eq) and ethylene glycol (0.49mL, 8.40mmol, 2.0eq) into a 25mL two-necked flask , and then dissolve the yellow oil obtained in the previous step in isopropanol (4.0 mL), then add it to the reaction flask, reflux at 80 ° C for 20 h, cool to room temperature, filter with suction, and wash the filter residue with EA several times to obtain the filtrate. ...

technical field [0001] The invention relates to a method for manufacturing a photovoltaic cell. Background technique [0002] With the increase of global energy demand year by year and the depletion of primary energy such as oil and coal, people have invested more attention and research on renewable resources such as wind energy and solar energy. Among them, photovoltaic cells based on photovoltaic effect are one of the hot spots. one. [0003] At present, mature photovoltaic cells on the market are mainly inorganic photovoltaic cells based on monocrystalline silicon, polycrystalline silicon, amorphous silicon, galliumarsenide, indiumphosphide, and polycrystalline compound semiconductors. Among them, polycrystalline silicon and amorphous silicon photovoltaic cells are used in civilian applications. Dominant in the photovoltaic cell market. After more than 50 years of development, the photoelectric conversion efficiency of inorganic monocrystalline silicon photovoltaic ce...
