Nanotube solar cell shows potential

Carbon Nanotube Solar Cells

We present proof-of-concept all-carbon solar cells. They are made of a photoactive side of predominantly semiconducting nanotubes for photoconversion and a counter electrode made of a natural mixture of carbon nanotubes or graphite, connected by a liquid electrolyte through a redox reaction. The cells do not require rare source materials such as In or Pt, nor high-grade semiconductor processing...

Carbon Nanotube - Silicon Solar Cells

Fabrication of Novel High Potential Chromium-Doped TiO2 Nanoparticulate Electrode-based Dye-Sensitized Solar Cell (DSSC)

In the current study, pure TiO2 and Cr-doped TiO2 (Cr@TiO2) nanoparticles were synthesized via sol-gel method and the resulting materials were applied to prepare the porous TiO2 electrodes for dye-sensitized solar cells (DSSCs). It is hypothesized that the advantages of the doping of the metal ions into TiO2 lattice are the temporary rapping of the photogenerated electron-hole (charge carriers)...

Accessories to SIV Control: T Cell Vaccination Shows Potential

Non-human primate (NHP) models utilizing infection with simian Similarly, the value of this complex approach needs to be further evaluimmunodeficiency viruses (SIV) remain the most compelling means to inform mechanisms of protection and viremic control as a guide to development of HIV vaccines for prevention and therapy short of human efficacy trials (Hirsch and Lifson, 2000). Occasionally stud...

ZnO nanotube based dye-sensitized solar cells.

We introduce high surface area ZnO nanotube photoanodes templated by anodic aluminum oxide for use in dye-sensitized solar cells (DSSCs). Atomic layer deposition is utilized to coat pores conformally, providing a direct path for charge collection over tens of micrometers thickness. Compared to similar ZnO-based devices, ZnO nanotube cells show exceptional photovoltage and fill factors, in addit...
