Carbon Nanotube Solar Cells

The effect of dry shear aligning of nanotube thin films on the photovoltaic performance of carbon nanotube–silicon solar cells

Recent results in the field of carbon nanotube-silicon solar cells have suggested that the best performance is obtained when the nanotube film provides good coverage of the silicon surface and when the nanotubes in the film are aligned parallel to the surface. The recently developed process of dry shear aligning - in which shear force is applied to the surface of carbon nanotube thin films in t...

High-Performance Dye-Sensitized Solar Cells with Conducting Polymer/ Carbon Nanotube Composites as counter electrode

Polymer Solar Cells with Polymer/Carbon Nanotube Composite Hole- Collecting Buffer Layers

We report the performance of polythiophene/fullerene solar cells with a hole-collecting buffer layer that was made using composite films of functionalized multi-walled carbon nanotube (f-MWCNT) and poly(3,4ethylenedioxythiphene):poly(styrenesulfonate) (PEDOT:PSS). The MWCNT was functionalized with carboxyl groups to bestow solubility in a weak base solvent for mixing with PEDOT:PSS. Results sho...

High Efficient Transparent TiO2 Nanotube Dye-Sensitized Solar Cells: Adhesion of TiO2 Nanotube Membrane to FTO by Two Different Methods

In order to fabricate transparent TiO2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from Ti substrate by a re-anodization method. The membranes are transferred on FTO glass by two different methods. At the first one, 100mM Ti-isopropoxide is used to make TiO2 nanoparticles for adhering TiO2 nanotube membranes to FTO and ...

Direct Absorption Solar Collector using Carbon Nanotubes Nanofluid: An Experimental Investigation

In this study, the efficiency of direct absorption solar collector (DASC) using carbon nanotube nanofluid in the mixture of water and ethylene glycol as the base fluid was experimentally investigated and compared with the efficiency of the flat plate solar collector (FPSC). The results show that the maximum efficiency of the DASC using the base fluid and absorptive bottom surface is about 4.7% ...

Fiber and fabric solar cells by directly weaving carbon nanotube yarns with CdSe nanowire-based electrodes.

Electrode materials are key components for fiber solar cells, and when combined with active layers (for light absorption and charge generation) in appropriate ways, they enable design and fabrication of efficient and innovative device structures. Here, we apply carbon nanotube yarns as counter electrodes in combination with CdSe nanowire-grafted primary electrodes (Ti wire) for making fiber and...
