Worldwide concern over the consequences of traditional energy usage is driving the development of devices for clean energy conversion such as fuel cells and solar cells. Polymer films and membranes play a central functional role in the efficiency and operation of these devices. Polymer electrolyte membranes (PEM) for the conduction of either protons or hydroxide ions, depending on the fuel cell device, have been extensively studied and improved over the last decade. Design of polymeric materials that address a number of issues including high ionic conduction under reduced humidity conditions, fuel crossover, the balance between water uptake / dimensional stability and proton conduction, chemical stability, the catalyst—PEM interface, ionomer, and fuel cell durability are needed. In organic solar cells, polymers have the advantage of much lower cost compared to silicon devices, and can be manufactured in high volume as printed flexible sheets. Polymeric semiconducting materials that address thermal, chemical, photo-stability and phase separation between n-type and p-type polymers are needed to improve durability. With power conversion efficiencies now approaching ~10%, further improvements in low bandgap polymer solar cells through the control of HOMO-LUMO charge separation will close the gap further with the ~25% conversion efficiencies of silicon-based solar cells.
