The invention relates to a heterojunction type green light detector of a subphthalocyanine derivative and a preparation method of the heterojunction type green light detector. The subphthalocyanine derivative is divided into one kind of P-type subphthalocyanine and three kinds of N-type subphthalocyanine, all sensitive to green light. A heterojunction in the photoelectric detector comprises a P-type subphthalocyanine film and an N-type subphthalocyanine film which are adjacent to each other. A hole transport layer PEDOT:PSS and transparent conductive substrate ITO glass are sequentially arranged on one side of the P-type subphthalocyanine thin film, and an electron transport layer C60, an electron buffer layer LiF and a metal back electrode Ag are sequentially arranged on one side of the N-type subphthalocyanine thin film. According to the subphthalocyanine derivative disclosed by the invention, the intramolecular transition dipole distance is larger than that of subphthalocyanine. Onthe basis of the P/N hete
