Heterostructured Photoactive Film

Description:

 

Background:

Heterostructured films can be used in a wide array of devices such as solar cells, transistors, and semiconductor lasers.  Research for these films have focused mainly on zero dimensional (0D) configurations which are less efficient compared to one dimensional (1D) configurations. Our researchers at the University of Nevada, Reno have used this knowledge to create a novel approach to assemble a 1D oxide-1D chalcogenide heterostructured photoactive film.

 

Description:

Our invention presents a unique low melting point metal catalyzed 1D/1D oxide−chalcogenide treelike heterostructure which uses a combination of the reductive successive-ionic-layer-adsorption-reaction technique and the solution-liquid-solid approach.  This technology can be applied for sensing, environmental monitoring, energy conversion, and display devices. This heterostructured photoactive film will benefit the industry because of its exemplary photoelectrochemical results and its many possible applications such as clean fuel generation, optoelectronics and photovoltaics.

 

Advantages:

  • This heterostructured film can be used in a variety of uses such as pollution control, waste remediation, and energy generation.
  • The 1D configuration in this technology can serve as a better way for a more rapid electron transport process which leads to added efficiency.
  • The highlights of the photoelectrochemical results include:
  • The formation of a stable heterostructure between titanium dioxide nanotube and cadmium selenide nanowire
  • Excellent light conversion efficiency
  • A photocurrent density of 3.84 mA/cm2
