Abstract:
We present 2,3,10,11‐tetrapropyl‐1,4,9,12‐tetraphenyl‐diindeno[1,2,3‐cd:1′,2′,3′‐lm]perylene (P4‐Ph4‐DIP) as new green donor for small molecule organic solar cells (SMOSC). P4‐Ph4‐DIP absorbs in the green spectral range of 490–580 nm and thus is a decisive building block towards br oad coverage of the sun spectrum. SMOSC with P4‐Ph4‐DIP as donor and C 60 as blue‐absorbing acceptor display very high fill factors FF 〉 76% and open circuit voltages of 0.99 V, reaching η = 1.92% for 12 nm P4‐Ph4‐DIP. Current voltage and external quantum efficiency spectra suggest that an exciton diffusion length E D 〈 20 nm is the main limiting factor. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
