Invention:
This invention solves the problem of interfacial mis-matches and defects between perovskite and metal oxide layers in photovoltaic (PV) cells, enabling improved solar cell efficiency and longer lifetime, with a practical, mass-producible method for manufacture.
Background:
In the past few years improvements in perovskite-based solar cells have led to an increase in power efficiency. However, the interface of MOx electrical contacts and perovskite layers are believed to limit lifetime and efficiency. This invention solves this problem via interface modifications during the production of the PV layers.
Applications:
- Third generation solar cell design
- Perovskite-based electrochemical systems
Advantages:
- Inexpensive due to low material costs
- Bandgap tunability, high charge carrier mobility and long electron-hole diffusion lengths
- High energy conversion efficiency
- Long term stability
