Record Efficiency for Plastic Solar Cells

Researchers find a new way to make cheap and flexible photovoltaic cells

A new process for printing plastic solar cells boosts the power generated by the flexible and cheap form of photovoltaics. Initial solar cells made with the technique can, according to a report in today's issue of Science, capture solar energy with an efficiency of 6.5 percent--a new power record for photovoltaics that employ conductive plastics to generate electricity from sunlight. Most photovoltaics are made from conventional inorganic semiconductors.
