| Outline of Final Research Achievements |
This research project is aimed at improving the stability and durability of perovskite solar cells. Innovations in materials and cell structure design are informed by evaluating the operating lifetime of the devices and investigating the mechanisms for the degradation and loss.
I evaluated p-i-n perovskite solar cells fabricated with MeO-2PACz, a molecular monolayer hole extraction layer (HEL), as potential candidates for ambient light harvesting applications. The durability of these devices was found to be significantly better than previous reference devices with n-i-p structure based on Spiro-OMeTAD hole transport layers.

| Academic Significance and Societal Importance of the Research Achievements |
Metal-halide perovskites are cheap and efficient materials for generating solar power, but are currently much less stable than silicon. Monitoring the degradation of perovskite solar cells is a key aspect to realize their successful commercial development and decrease our reliance on fossil fuels.
