    • Plasmonically enhanced hot electron based photovoltaic device 

      Atar F.B.; Battal, E.; Aygun L.E.; Daglar, B.; Bayındır, Mehmet; Okyay, Ali Kemal (Optical Society of American (OSA), 2013)
      Hot electron photovoltaics is emerging as a candidate for low cost and ultra thin solar cells. Plasmonic means can be utilized to significantly boost device efficiency. We separately form the tunneling metal-insulator-metal ...
    • Semiconductor-less photovoltaic device 

      Atar, Fatih B.; Battal, Enes; Aygun, Levent E.; Dağlar, Bihter; Bayındır, Mehmet; Okyay, Ali Kemal (IEEE, 2013)
      We demonstrate a novel semiconductor-less photovoltaic device and investigate the plasmonic effects on this device structure. The device is made of metal and dielectric layers and the operation is based on hot carrier ...
    • Strongly Scale-Dependent Charge Transport From Interconnections of Silicon Quantum Dots and Nanowires 

      Ilday, S. (Cambridge University Press, 2017)
      We present the first characterization of strongly scale-dependent charge transport of a unique, hierarchical complex topology: an interconnected random network of silicon quantum dots (QDs) and nanowires. We show that this ...
    • Triangular metallic gratings for high efficiency thin film solar cells 

      Battal, Enes; Yoǧurt, Alper Taha; Aygun, Levent Erdal; Okyay, Ali Kemal (IEEE, 2011)
      Our design of novel nanometallic structure integrated with photovoltaic devices provides polarization insensitive, broadband and significantly high absorptivity enhancement. This structure attains absorptivities higher ...
