Side-Strapped Phthalocyanines as Materials for Organic Electronics

This invention describes a novel side-strapped derivative of phthalocyanine for use in photovoltaic cells to generate a current in a more efficient manner.

Background:
Within the context of photovoltaic solar power, there are other compounds based on the phthalocyanine structure that are in use currently. These other compounds have an energy conversion of 11% at their highest. The variations of the core molecule come chiefly from the different metals places in the complex onto it, including: copper, aluminum, and palladium.

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 phthalocyanine
• 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
