05 April 2013 ICFO teams up with BASF Germany

This collaboration leads to industrially relevant advances published in two recent papers. The development of new transparent electrodes that have high electro-optical performance and at the same time are inexpensive and mechanically flexible is essential for a wide range of industrial products, especially those fabricated using low cost roll-to-roll techniques. A productive collaboration combining ICFO’s technology on ultrathin metal based transparent electrodes, developed by the Optoelectronics group led by Valerio Pruneri, and BASF’s know-how on organic materials for solar cells has led to photovoltaic devices which have conversion efficiencies from light to electricity comparable to state of the art counterparts incorporating more expensive and fragile Indium Tin Oxide (ITO), the most commonly used transparent electrode material in the market today.

In the future, higher efficiencies will be achieved by optimizing the multilayer structure. The team aims at demonstrating the production of such devices in a roll-to-roll configuration.
