One major problem of the conventional solar cells is low conversion efficiency. In this work, we have proposed a new design including hemisphere texturing on top and metallic plasmonic nanostructure under the silicon layer to enhance the optical absorption inside the photosensitive layer.    The finite-difference time-domain (FDTD) method has been used to investigate the interaction of light wi...

Nanostructures of noble metal materials have been used in organic solar cells for enhancement of performance and light trapping. In this study, we have introduced branched silver cauliflower-like nanopatterns as sub-wavelength structured metal grating in organic solar cells. Self-assembled fabrication process of branched nanopatterns was carried out on a bio-template of cicada wing nanonipple a...

We discuss a generalized model for a solar cell, and the realization with heterogeneous photochemical photovoltaic converters such as the dye-sensitized solar cell. The different steps involved in the conversion of photon energy to electrical energy, indicate that a key point to consider is maintaining the separation of Fermi levels in the selective contacts to the absorber. In order to underst...

In March 2009, NASA will launch the Kepler satellite—a mission designed to discover habitable Earth-like planets around distant Sun-like stars. The method that Kepler will use to detect distant worlds will only reveal the size of the planet relative to the size of the host star, so part of the mission is devoted to characterizing other suns using asteroseismology. In this proceedings, I give a ...

Tellurium (Te) nanostructures have been successfully synthesized via a simple hydrothermal methodfrom the reaction of a TeCl4 aqueous solution with thioglycolic acid (TGA) as a reductant. TGA can be easily oxidized to the corresponding disulfide [SCH2CO2H]2, which in turn can reduce TeCl4 to Te. The obtained Te was characterized by XRD, SEM, EDS, and DRS. The effect of reducing agent on morphol...

Dye sensitized solar cell was fabricated from a double layer photoanode. First, TiO2 nanoparticles  were synthesized by hydrothermal method. These TiO2 NPs were deposited on FTO glasses by electrophoretic deposition  method in applied voltage of 5 V and EPD time of 2.5-10 min. Then TiO2 hollow spheres (HSs) were synthesized by sacrificed template method with Carbon Spheres as template and TTIP ...

Solar cells transparent in the visible range are highly requested for integration see-through photovoltaic (PV) applications such as building glass façades or greenhouse roofs. The development of advanced PV can fully exploit tandem technology where top cell absorbs near-ultraviolet solar spectrum while bottom one near-infrared part. Herein, a possible implementation this paradigm, namely, stru...
