“…PcZn films were deposited onto the CdS single crystal surface by thermal vacuum evaporation technique under a pressure of 10 −3 Pa. Thickness of the PcZn films was evaluated through the quartz microbalance technique and was in the range of 10–40 nm. Gold was chosen as a top electrode for PcZn films, since it provides, to our knowledge, the best contact for PcZn among other metals 8.…”

Photovoltaic (PV) response of hybrid organic/inorganic bilayer heterostructures based on organic polymers or small molecules on the one hand, such as poly(3‐hexylthiophene), polyaniline doped with poly(styrenesulfonic acid), poly(ethylene‐3,4‐dioxythiophene) doped with poly(styrenesulfonic acid) (PEDOT:PSS), phthalocyanine, and inorganic CdS or CdSe single crystals on the other hand, has been studied depending on the crystal facet used. The effect of the surface‐terminated layer of the crystal on the PV performance of hybrid heterojunctions has been observed. It was found that the different crystal facets could render both quantitative and qualitative effect on PV properties of the hybrid heterojunctions. Photocurrent spectra of CdS/PEDOT:PSS heterojunctions based on the Cd‐terminated (solid curve) and S‐terminated (dashed curve) crystal facet.

“…Electrical properties of organic semiconductors are dependent on ambient conditions, [1][2][3][4][5][6] and this makes them very promising for the development of various types of gas or vapor sensors including humidity [1][2][3] sensors. Metal phthalocyanines (MPc's) are very attractive organic materials as sensing elements in gas sensors because of their high chemical and thermal stability, 7,8 their ability to be deposited as thin layers and their high electrical conductivity variations in the presence of some active gases (i.e.…”

Nanostructured organic–inorganic heterojunction diodes as gas sensors

et al. 2012

Nanostructured organic-inorganic heterojunction devices were fabricated by employing n-type zinc sulphide (ZnS) grown on ITO by RF magnetron sputtering and thin film of zinc phthalocyanine (ZnPc) deposited on the top of the ZnS layer by thermal evaporation. On the top of the ZnPc layer, an Al film was coated to form an electrode. Thin films of ZnS and ZnPc were characterized by optical absorption and Field Emission Scanning Electron Microscopy (FESEM). Current-voltage (I-V) characteristics of the fabricated ITO/ZnS/ZnPc/Al hetero-structures were studied at different temperatures (30 to 90 uC) in vacuum and diode-like behaviour was observed. In the case of single layer devices ITO/ZnS/Al and ITO/ZnPc/Al diode-like behavior was not obtained. The effects of donor ammonia and acceptor oxygen gases on the electrical properties of single layer devices ITO/ ZnS/Al, ITO/ZnPc/Al and ITO/ZnS/ZnPc/Al heterojunctions were studied in order to investigate the utility of these devices as gas sensors. A drastic increase in forward current of the heterojunction has been noticed in the presence of donor ammonia gas containing water vapor, while a decrease in forward current has been noticed in the presence of acceptor oxygen gas. This change in forward current (diode current) in the presence of gases (under doped conditions) has been explained by the creation of charge carriers inside the ZnPc layer and hence bending of ZnPc bands. The threshold voltage (V th ) of the junction diodes has been found to depend on the temperature and the presence of donor and acceptor gases. Our experimental results suggest that this heterojunction diode could be a novel candidate for gas sensors.

“…Although the solar cells based on CdS nanocrystals usually do not demonstrate superior power conversion efficiency (PCE) (Table 1 ), this material is convenient to study as a proof of concept for new cell geometries and to model hybrid interface properties [ 4 , 14 – 16 ] due to the abovementioned advantages.…”

In this work, a method to assemble nanoscale hybrid solar cells in the form of a brush of radially oriented CdS nanowire crystals around a single carbon fiber is demonstrated for the first time. A solar cell was assembled on a carbon fiber with a diameter of ~5–10 μm which served as a core electrode; inorganic CdS nanowire crystals and organic dye or polymer layers were successively deposited on the carbon fiber as active components resulting in a core-shell photovoltaic structure. Polymer, dye-sensitized, and inverted solar cells have been prepared and compared with their analogues made on the flat indium-tin oxide electrode.
