Problems solved by technology

Another method is to introduce 0.1%-2% initiator with crosslinking agent components into the active layer, but this method will introduce some defect states in the actual operation process, because the chemical reaction of the initiator is a decomposition reaction, The mechanism of action is that the decomposed free radicals promote the chemical polymerization of the donor material or the acceptor material, thereby improving the stability, which will lead to the weakening of the electron extraction ability of the material, resulting in a lower fill factor
