DYE- SENSITIZED SOALR CELL

摘要

The present invention provides a solid-state p-n heterojunction comprising an n-type material in contact with a p-type material, wherein at least one of said n-type material and said p-type material comprises an organic polymeric charge transporter having a low band gap, and wherein said heterojunction further comprises a light harvesting antenna (LHA) material having a band gap of no less than 1.5 e V and greater than the band gap of said organic polymeric charge transporter. The invention further provides optoelectronic devices comprising at least one such solid state p-n heterojunction, along with methods for the manufacture of such solid-state p-n heterojunctions.
