Claim:
1. A dye-sensitized solar cell containing a photosensitive porphyrin-based dye coated on a semiconductor film, the photosensitive porphyrin-based dye having a structural formula (I): D representing an electron donor unit selected from a group consisting of: wherein R=C n H 2n+1 and n=1 to 12; A representing an electron acceptor unit selected from a group consisting of: and P representing a blocker unit selected from a group consisting of: wherein R 1 ═C n H 2 F 2n−1 , OC n H 2n+1 or OC n H 2 F 2n−1 , n=1 to 12, and wherein R 2 =C n H 2n+1 , C n H 2 F 2n−1 , OC n H 2n+1 or OC n H 2 F 2n−1 , n=1 to 12, two blocker units Pin the structural formula (I) being identical or different.
