Why Polymer Solar Cells Deserve Their Place in the Sun

Organic polymer solar cells show potential to provide solar power to remote microwatt sensors, wearable technology and the Wi-Fi-connected appliances constituting the “internet of things.” While PSCs cannot match the durability or efficiency of inorganic solar cells, the potential to mass-produce nontoxic, disposable solar panels using roll-to-roll production makes them attractive for additional applications. In this week’s Journal of Renewable and Sustainable Energy, researchers review the latest advances and remaining challenges in PSC technology.
