Abstract

The costs of large area, organic photovoltaic devices are stronly related to their module efficiency. Even for niche markets, such as consumer electronics, efficiency is imperative since the available area is limited. Therefore, if polymer photovoltaics is to become a mature technology, it is key to increase the power conversion efficiency of the devices. In our contribution an analysis is given of the energy loss factors in P3HT:[C6O]PCBM cells. The main loss occurs as a voltage loss at the donor-accpetor interface. Since this loss factor is linked to the HOMO-LUMO levels of the system, it is impossilble to reduce this loss using the same material combination. We present polymer: [C6O]PCBM cells with similar optical properties but with a reduced voltage loss at the interface, leading to enhanced open circuit Voltage of 1.0 V (compared to 0.62 V for P3HT:[C6O]PCBM devices). The polymer is an alternating copolymer with fluorence and benzothiadiazole units (PFTBT). Well-characterised devices yield already an AM 1.5 efficiency of 4%, thus competing with state-of-the-art P3HT:PCBM devices.
