Phillips 66 has announced they have successfully set a "new world record" in power conversion efficiency for polymer-based single junction organic photovoltaic (OPV) cells. The 11.84% efficiency has been certified by Newport Corporation - a recognised centre for independent verification of solar cell results under standard testing conditions.
According to the announcement the solar cells are based on proprietary state-of-the-art polymers and interfacial layers, which have been developed by Phillips 66. Phillips 66 added they believe their materials provide the potential for cost-effective renewable electricity generation on par with conventional energy technologies. Nor do their organic solar cells contain hazardous components, such as lead or cadmium, unlike some other types of thin film technologies.

Phillips 66 said their research cell were 0.0406 cm2, and used an inverted architecture, and that the active layer and interfacial layers used in the cell were prepared by Phillips 66.
Phillips 66 are continuing to develop the OPV technology towards commercialisation by improving the performance of the cells and focus on scaling-up the technology.
Further, Phillips 66 said their OPV technology could be printed using roll-to-roll manufacturing processes, enabling the development of flexible, lightweight and transparent solar modules that can be manufactured at lower costs.
Merl Lindstrom, vice president of Technology at Phillips 66, said, "This breakthrough in efficiency brings us closer to the possibility of commercializing this promising form of solar technology." Merl added, "Continuing to increase the ability of OPV cells to convert power with high efficiency will one day make this energy source more affordable for the consumer."
