Inhibiting electrode corrosion via defects anchoring spatial confinement strategy for enhancing the stability of inverted perovskite solar cells

Key Points

• The aim is to develop a strategy for preventing electrode corrosion while maintaining the stability of perovskite solar cells.
• Introduced defect anchoring spatial confinement strategy.
• Utilized diethyl dithiocarbamate zinc (ZETC) as an anti-solvent additive.
• Constructed a Pb(ETC)2 interface layer at the perovskite/electron transport layer interface.
• Achieved dual function of defect anchoring and material diffusion limitation.
• Achieved a photovoltaic conversion efficiency of 26.91%.
• Maintained 90% of initial efficiency after 1000 hours under one-sun illumination.
• Retained 90% efficiency after 800 hours of exposure at 65°C under light.
