The invention discloses the application of a fullerene as a catalyst in the catalytic hydrogenation reaction of nitro groups in nitroaromatic compounds under light irradiation conditions. Nitroaromatic compounds include nitrobenzene, chloronitrobenzene and nitroaromatic ketones and nitriles. The fullerene catalyst is any one of monovalent C60 anion, neutral C60 or neutral C70. The invention utilizes a non-metallic catalytic system to activate hydrogen molecules and selectively catalyze the hydrogenation reaction of nitro groups under light irradiation, normal temperature and normal pressure conditions. The fullerene catalyst has the outstanding advantages of high activity and high selectivity. Ecological hazards and environmental hazards generated by catalytic reactions are reduced.

The invention belongs to a method producing solar cell by polymer, greatly improving crystallinity of P3HT in a blending film of a P3HT and C60 fullerene or a derivative PCBM of P3HT and ensuring whisker of P3HT in the blending film which is in a micro length to be uniformly dispersed on the whole film and having a nano-sized separation distance. By using the method, the transferring efficiency of solar cell arrives at 3.9 percent while the transferring efficiency of solar cell processed by thermal annealing can only reach 3.7 percent, which shows that through the method the high performed and non-annealed polymer solar cell can be produced by one step.
