High-Efficiency Indoor Perovskite Photovoltaics on Ultra-Thin Glass
A revolution is already under way which includes development of autonomous wireless sensors, low-power consumer electronics, smart homes, domotics and the Internet of Things. All these elements require efficient and easy-to-integrate energy harvesting devices for their power. Indoor photovoltaic (PV) power sources, on ultra-thin curvable substrates, will have the potential to facilitate these technological innovations if they can provide sufficient energy under indoor illumination rather than the sun to the electronic components, while remaining small, convenient and economical. An international team with researchers from University of Rome – Tor Vergata, Universidad Surcolombiana, and the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology has published results in Cell Reports Physical Science which highlights the progress made in achieving efficiencies above 20% under indoor illumination using flexible perovskite solar cells fabricated on ultra-thin glass. The efficiencies obtained represent the highest reported for any indoor photovoltaic cell technology that is flexible and curvable, as well as surpassing by a 60-90% margin the prior best-performing perovskite photovoltaic cells on flexible substrates. Specific powers in Watts delivered per gram of weight (W/g) are 40-55% higher than their counterparts on plastic PET films and an order of magnitude greater than those on rigid glass.
