Title: Side-Strapped Phthalocyanines as Materials for Organic Electronics

 

Invention: The invention describes a novel side-strapped derivative of pthalocyanine for use in photovoltaic cells to generate a current in a more efficient manner. We have a notice of allowance on US 14/672,124.

 

Background: Within the context of photovoltaic solar power, there are other compounds based on the pthalocyanine structure that are in use currently. These other compounds have an energy conversion of 11% at their highest (Walter, et. al 759). The variations of the core molecule come chiefly from the different metals places in the complex onto it, including: copper, aluminum, and palladium (Walter, et. al 764). These alternate compounds still have to overcome a series of challenges to generate higher energy conversion percentages.

  

Applications:

  • Use in a photovoltaic cell
  • Possible new generation of solar panels

Advantages:

  • Sensitivity to near infra-red light allows the cell to intake more light to use in generating currents
  • Greater charge mobility compared to other derivatives of pthalocyanine
  • Low production costs, making it a viable choice for the development of new photovoltaic cells
  • Increased energy output creates significantly more efficiency due to higher sensitivity to wavelengths of light
