      Article
      Open Access
      Future optoelectronic devices and their low-cost roll-to-roll production require mechanically flexible transparent electrodes (TEs) and substrate materials. Indium tin oxide (ITO) is the most widely used TE because of its ...

    • Circumventing UV light induced nanomorphology disorder to achieve long lifetime PTB7-Th:PCBM based solar cells 

      Liu, Quan; Toudert, Johann; Liu, Fengqing; Mantilla Perez, Paola; Montes Bajo, Miguel; Rusell, Thomas P.; Martorell Pena, Jordi (2017-07-17)
      Article
      Open Access
      Large area flexible electronics rely on organic or hybrid materials prone to degradation limiting the device lifetime. For many years, photo-oxidation has been thought to be one of the major degradation pathways. However, ...

    • Enhanced light harvesting in semitransparent organic solar cells using an optical metal cavity configuration 

      Pastorelli, Francesco; Romero Gómez, Pablo; Betancur Lopera, Rafael; Martinez Otero, Alberto; Mantilla Perez, Paola; Bonod, Nicolas; Martorell Pena, Jordi (2015-01-21)
      Article
      Open Access
      An optical metal cavity configuration is used to trap near infrared light in a semitransparent organic solar cell. The efficiency for such cell, which has a higher than 20% transparency in the visible region, is equal to ...
