Abstract

The invention belongs to the field of polymer solar cell materials, in particular to an alcohol-soluble polymer solar cell cathode modification material and a modification method thereof. In the invention, the tantalum methoxide solution is processed on the photoelectric active layer or the cathode layer by spin coating to form a tantalum methoxide film and obtain the cathode modification layer. The invention introduces tantalum methoxide into the solar cell to replace the original active metal with low work function, can selectively collect electrons, block holes, and form an ohmic contact with the active layer, so that the open circuit voltage of the device can reach an optimal value, and With optical spacer effect, the internal optical field is redistributed, thereby enhancing light absorption, and exhibiting excellent performance in polymer solar cells. The preparation of the cathode modification layer of the polymer solar cell of the present invention also has the characteristics of simple process, low cost, good experiment repeatability, suitable for large-scale industrial production and the like.

Description

technical field [0001] The invention belongs to the field of polymer solar cell materials, in particular to an alcohol-soluble polymer solar cell cathode modification material and a modification method thereof. Background technique [0002] Energy is the material basis for human survival and development. In recent decades, energy issues have always been a major issue that has attracted worldwide attention. Regardless of the changes in the supply and demand of conventional energy in a short period of time, considering the longer period in the future, conventional energy with limited reserves will undoubtedly gradually decline. In order to survive and develop sustainably, human beings must seek new energy sources that can replace conventional energy sources. Harnessing solar radiant energy is one of its optional goals. After mankind entered the 21st century, the pace and intensity of exploration, development, and utilization of solar energy are increasing. As a clean energ...
