    • Effects of Nanostructure Geometry on Nanoimprinted Polymer Photovoltaics 

      Yang, Yi; Mielczarek, Kamil; Aryal, Mukti; Zakhidov, Anvar A.; Hu, Wenchuang (Walter) (RSC Pub, 2014-04-23)
      We demonstrate the effects of nanostructure geometry on the nanoimprint induced poly(3-hexylthiophene-2,5-diyl) (P3HT) chain alignment and the performance of nanoimprinted photovoltaic devices. Out-of-plane and in-plane ...
    • Halide-Perovskite Resonant Nanophotonics 

      Makarov, S.; Furasova, A.; Tiguntseva, E.; Hemmetter, A.; Berestennikov, A.; Pushkarev, A.; Zakhidov, Anvar A.; Kivshar, Y.
      Halide perovskites have emerged recently as promising materials for many applications in photovoltaics and optoelectronics. Recent studies of optical properties of halide perovskites suggest many novel opportunities for a ...
    • Room Temperature Operation of Directly Patterned Perovskite Distributed Feedback Light Source under Continuous-Wave Optical Pumping 

      Gharajeh, Abouzar; Haroldson, Ross; Li, Zhitong; Moon, Jiyoung; Balachandran, Balasubramaniam; Hu, Wenchuang (Walter); Zakhidov, Anvar A.; Gu, Qing
      We report the first directly patterned perovskite distributed feedback (DFB) resonator with a narrow amplified spontaneous emission (ASE) at pump powers as low as 0.1W/cm², under continuous-wave (CW) optical pumping condition ...
    • Tunable Hybrid Fano Resonances in Halide Perovskite Nanoparticles 

      Tiguntseva, E. Y.; Baranov, D. G.; Pushkarev, A. P.; Munkhbat, B.; Komissarenko, F.; Franckevičius, M.; Zakhidov, Anvar A.; Shegai, T.; Kivshar, Y. S.; Makarov, S. V.
      Halide perovskites are known to support excitons at room temperatures with high quantum yield of luminescence that make them attractive for all-dielectric resonant nanophotonics and meta-optics. Here we report the observation ...
    • Tunable Organic PV Parallel Tandem with Ionic Gating 

      Saranin, Danila; Ishteev, Artur; Cook, Alexander B.; Yuen, Jonathan D.; Kuznetsov, Denis; Orlova, Marina; Didenko, Sergey; Zakhidov, Anvar (Amer Inst Physics, 2018-10-22)
      A novel type of tunable organic photovoltaic (OPV) tandem device with ionic gating by in-situ ionic liquid is presented. This device is comprised of two solution-processed polymeric OPV cells connected in parallel by a ...
