If we fabricate a heterojunction from TiO[2] and lead phthalocyanine (PbPc is an organic semiconductor) by thermal evaporation technique (first a thin film of TiO[2] deposited on a substrate and then a thin film of PbPc) we just have a p-n heterojunction...

I read a paper that have studied this heterojunction and introduced it as a composite
