Organic Solar Cells: Power From Plastic Photovoltaics

Polymer-based solar cells continue to show promise as low-cost electricity generators
Department: Science & Technology
Keywords: photovoltaics, plastic solar cells, organic photovoltaics, Heeger

“A decade ago we had vague concepts and power conversion efficiencies of just 1%. We have made tremendous progress since then.”

That perspective, from Nobel Laureate and University of California, Santa Barbara, chemistry professor Alan J. Heeger, sums up the status of organic photovoltaic (OPV) devices, which convert light to electricity. Scientists and engineers working in this field are out to develop polymer-based solar panels that are flexible and low cost, . . .
