It is famous to dope metal complexes in conjugate polymer. Heavy metal effect cause excitons have spin-orbit coupling. Singlet excitons can be cross to the triplet state by intersystem crossing. Excitons lifetime will increase obviously. After we doped PtOEP in conjugate polymer and device, it find the decreasing exciton lifetime. In bilayer devices , it can find the exciton diffusion length increase. The bilayer devices fabrication was post anneal 30mins and in 180 degrees. The photocurrent and PCE also increase in evidence.
