For decades, polymer scientists and synthetic chemists working to improve the power conversion efficiency of organic solar cells were hampered by the inherent drawbacks of commonly used metal electrodes, including their instability and susceptibility to oxidation. Now for the first time, researchers have developed a more efficient, easily processable and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the 'electrode barrier.'
