Relative Photon-to-Carrier Efficiencies of Alternating Nanolayers of Zinc Phthalocyanine and C-60 Films Assessed by Time-Resolved Terahertz Spectroscopy
Esentürk, Okan; Lane, Paul A.; Heilweil, Edwin J. (American Chemical Society (ACS), 2009-10-29)
Multilayer and 1:1 blended films of zinc phthalocyanine (ZnPc) and buckminsterfullerene (C-60) were investigated as model active layers for solar cells by time-resolved terahertz spectroscopy (TRTS). Relative photon-to-carrier efficiencies were determined from ultrafast decay dynamics of photogenerated carriers using 400 and 800 nm excitation for delay times up to 0.5 ns. The findings are in good agreement with reported solar-cell device measurements, and the results exhibit a near linear increase of the re...
PHOTO-CARRIER DYNAMICS OF BLENDED AND MULTI-LAYERED FILMS OF ZINC PHTHALOCYANINE AND C-60 MEASURED BY TIME-RESOLVED TERAHERTZ SPECTROSCOPY
Melinger, Joseph S.; Lane, Paul; Esentürk, Okan; Heilweil, Edwin (2010-06-25)
We present a study of photo-induced carrier dynamics in organic thin films that contain zinc phthalocyanine (ZnPc) and buckminsterfullerene (C-60) investigated by ultrafast time resolved terahertz spectroscopy (TRTS). We compare two classes of films: 1) blend films of ZnPc and C-60 prepared by co-evaporation, and 2) superlattice films from alternating neat layers of ZnPc and C-60, where the individual layer varies in thickness between 2 nm and 40 nm. These films are model structures for the charge generatio...
Investigation Of The Device Properties Of Cztse Thin Films For Solar Cells
Bayraklı, Özge; Güllü, Hasan Hüseyin; Parlak, Mehmet (2016-10-02)
Thin Film Solar Cell has received a considerable attention in the photovoltaic industry. While the efficiency of thin film amorphous silicon is about %14, the efficiency of Cu(In,Ga)Se2 (CIGS) thin film based solar cells ,is very popular in the recent year, reached the value of %20. But CIGS based solar cells have some constraints such as its extensive and large scale production in terms of availability of its constituent elements. On the other hand, Kesterit based solar cells such as Cu2ZnSnSe4 (CZTSe) hav...
Transparent thin film heaters based on silver nanowire networks
Ergün, Orçun; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2015)
Transparent thin film heaters are used in various de-fogging and de-icing applications because of their ability to convert electrical energy to thermal energy while allowing to transmit solar light through a surface. Indium tin oxide (ITO) is the conventional transparent conducting material used in transparent thin film heaters. However, due to scarcity of indium and its increasing prices worldwide, coupled with the inflexibility of ITO, alternative materials are being investigated. Silver nanowire networks...
Efficient Light Trapping in Inverted Nanopyramid Thin Crystalline Silicon Membranes for Solar Cell Applications
MAVROKEFALOS, Anastassios; HAN, Sang Eon; Yerci, Selçuk; Branham, Matthew S.; CHEN, Gang (2012-06-01)
Thin-film crystalline silicon (c-Si) solar cells with light-trapping structures can enhance light absorption within the semiconductor absorber layer and reduce material usage. Here we demonstrate that an inverted nanopyramid light-trapping scheme for c-Si thin films, fabricated at wafer scale via a low-cost wet etching process, significantly enhances absorption within the c-Si layer. A broadband enhancement in absorptance that approaches the Yablo-novitch limit (Yablo-novitch, E. J. Opt. Soc. Am. 1987, 72, ...
