Due to the high demand for economical and eco-friendly renewable energy sources, Plextronics' new material developments target printable ink systems that allow for high efficiency solar performance. Solar cells based on Plextronics' XC-3000 low band-gap polymer showed 6.9% verified performance. Furthermore, indoor energy harvesting can be well suited to OPV technology due to potential for low cost, matching of OPV spectral response to indoor fluorescent lighting spectrum, and superior performance vs. crystalline silicon at very low light irradiance. Plextronics' inks based on p-type polymer XC-2010 can be used to achieve competitive power densities under office lighting levels (200 � 1000 LUX) to drive low power demand applications such as e-readers, motion and light sensors, and next generation displays. Development of materials for these two OPV applications will be presented along with materials properties and device data.
