Invention:
Researchers at the University of Arizona have integrated electrospun nanofibers into printable optoelectronic films to improve their stability and toughness. These nanofibers have the potential for improved efficiency in solar cells through light scattering.
Background:
Recent advances in the solar cell industry have led to the development of more efficient construction materials for solar cells. Perovskite-based solar cells have been competing with the best silicon-based photovoltaics due to their ability to exhibit greater efficiency than silicon-based ones.
Even though Perovskite based cells have greater efficiency that silicon-based ones, the cells still require improvements in both their thermomechanical and chemical stability required to achieve the Department of Energy SunShot goal of a $0.02−0.03 kWh−1 LCOE by 2030.
This invention aims to solve the problem by inserting nanofiber reinforcements into the cells to improve the stability of the Perovskite solar cell without sacrificing either efficiency or compatibility with the solar cell applications.
Applications:
- Printable electronic reinforcement
- Increase toughness of perovskite solar cells
Advantages:
- Improves stability of the perovskite solar cell without sacrificing efficiency or compatibility
- Low cost
