[Abstract]:Solar energy as a renewable clean energy, inexhaustible, and not limited by regional restrictions, safe and reliable, can be used on a large scale, has been widely concerned about the world, It is one of the new energy sources developed by scientists all over the world. Organic solar cells have a wide range of raw materials, cheap, with high absorption coefficient and good photovoltaic effect, the preparation process is flexible and simple, can be prepared on flexible substrates, so it has been widely concerned. As the hole transport layer and the electron barrier layer, the anode buffer layer is an indispensable part of the organic solar cells, which can greatly improve the performance of the devices. This article mainly carries on the following several aspects of research: 1. Study on the technological parameters of organic solar cells based on P3HT / PCBM: chlorobenzene and dichlorobenzene were used to prepare active layer precursor. The results show that the device efficiency using o-dichlorobenzene as solvent is 1.66, which is 20% higher than that with chlorobenzene as solvent, and the device efficiency is 1.74% higher than that without doping 3% 1 ~ (8%) diiodooctane diol in o-dichlorobenzene. The mass ratio of P3HT / PCBM is 1:1 and 1: 0.8, the device efficiency is 1.54% and 1.65%, and the fixed annealing time is 20 minutes. The results show that when the annealing temperature is between 130 鈩，
