“…A thin layer of Tc between PBrPc and Au should not limit the flow of holes from PBrPc to Au since it can be expected that the hole transporting levels of Tc and PBrPc coincide with each other. Therefore, Tc can be applied as a buffer layer between PBrPc which exhibits p-type electric transport, and Au in photovoltaic cells with organic heterojunction [16,17]. The average deposition rate of organic materials was equal to 0.5 Å/s.…”

“…Perylenes are attractive model electron acceptors for studies of charge photogeneration in donor/acceptor blends as their energetics can be readily modified by chemical substituents and they exhibit a well-defined and high-oscillator-strength anion absorption band (extinction coefficient ε ≈ 80 000 M −1 cm −1 compared to that of P3HT ∼20 000 M −1 cm −1 ). They have, moreover, already received significant attention for applications in dye-sensitized and vacuum-deposited solar cells, although their performance in organic polymer/perylene blend devices has been relatively poor to date, a result that has typically been attributed to unfavorable nanomorphologies for charge transport to the device electrodes. We have previously reported a comparison of charge photogeneration between polythiophene:PCBM blend films and the same polythiophenes blended with one perylene diimide electron acceptor (PDI 2 in Chart ).…”
