Problems solved by technology

However, the above-mentioned conjugated polyelectrolyte has the disadvantage of low hole mobility. When used in the hole transport layer of polymer solar cells, it must be processed very thin, generally less than 10 nanometers in thickness, so as to ensure that the battery has high photoelectric conversion efficiency. The processing technology is very harsh
