Invention:
This invention describes a novel side-strapped derivative of pthalocyanine 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 pthalocyanine 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. 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
Status: issued U.S. patent #9,425,413
