Self-filtering red narrowband photodetector based on a perovskite/organic multi-stack photoactive layer

Key Points

• The aim is to develop a photodetector that effectively operates within the red light spectrum for better physiological monitoring in biological tissues.
• Utilized a multi-stack photoactive layer combining perovskite and organic materials.
• Tested performance in response to red light (600-700 nm).
• Evaluated efficacy in penetration through biological tissues.
• The photodetector shows improved sensitivity and efficiency in the red wavelength range.
• Effective penetration of the red light through biological tissues was observed.
• Continuous physiological monitoring capabilities were enhanced.
