Novel Polymer Additive Significantly Improves Photovoltaic Efficiency of Existing Systems

University of Chicago, IL, United States

TECHNOLOGY SUMMARY

The Yu group has developed a polymer that, when incorporated as part of a ternary blend, increases the Power Conversion Efficiency (PCE) by 13%. The system widens the photon absorption range and increases the charge separation and transport resulting in PCE increases in each of the binary systems studied.

Primary Application Area: Energy & Efficiency

Technology Development Status: Prototype

Technology Readiness Level: TRL 3
