• closedAccess   Assessing possibilities and limits for solar cells 

      Nayak, Pabitra K.; Bisquert, Juan; Cahen, David Wiley (2011-05-05)
      What are the solar cell efficiencies that we can strive towards? We show here that several simple criteria, based on cell and module performance data, serve to evaluate and compare all types of today's solar cells. Analyzing ...
    • openAccess   Different approaches to improve perovskite-based photovoltaic and optoelectronic devices 

      Vallés Pelarda, Marta Universitat Jaume I (2022-01-21)
      Halide perovskites have had a huge impact on different fields in the last decade due to their versatility and amazing optoelectronic properties. However, there are still some issues to improve towards their future utilization ...
    • closedAccess   Flat-top ultra-wideband photonic filters based on mutual coherence function synthesis 

      Torres Company, Víctor; Lancis, Jesús; Andrés, Pedro Elsevier (2008)
      A novel all-incoherent optical circuit that allows for band-pass microwave-photonic filter design is presented and verified through numerical simulation. In contrast to conventional spectrum-sliced optical architectures ...
    • openAccess   Ionic charging by local imbalance at interfaces in hybrid lead halide perovskites 

      Almora Rodríguez, Osbel; Guerrero, Antonio; Garcia-Belmonte, Germà AIP Publishing (2016)
      Identification of specific operating mechanisms becomes particularly challenging when mixed ionic-electronic conductors are used in optoelectronic devices. Ionic effects in perovskitesolar cells are believed to distort ...
    • closedAccess   Operating modes of sandwiched light-emitting electrochemical cells 

      Lenes, Martijn; Garcia-Belmonte, Germà; Tordera, Daniel; Pertegás, Antonio; Bisquert, Juan; Bolink, Henk J. Wiley (2011-03-14)
      Light-emitting electrochemical cells (LECs) are promising lighting devices in which the redistribution of ionic charges allows for double electronic carrier injection from air-stable electrodes. Uncertainties about the ...
