摘要

We fabricated organic photovoltaic cells by using hexadecafluorophthalocyaninatocopper (F₁₆CuPc) as electron acceptor material and para-sexiphenyl (p-6P) as electron donor material. F₁₆CuPc has wide absorption spectrum from 550 nm to 850 nm, which covers the maximum of solar photo flux. The measurement of their external quantum efficiency (EQE) demonstrated that the photocurrent comes from the excitons created in F₁₆CuPc, which were separated into free electrons and holes at heterojunction interface of p-6P and F₁₆CuPc. Moreover, F₁₆CuPc with excellent air-stability improved the environmental stability of photovoltaic cells, and the unencapsulated cells exhibited the shelf lifetime of exceeding a week.
