Ultrahigh photovoltage responsivity of PEDOT:PSS–silicon hybrid heterojunction photodiodes
In brief
Low-temperature, solution-processed polymer–silicon photodiodes that run without external power and stay stable after long storage in air.
Key results- Self-powered photovoltage responsivity of 10⁶ V/W.
- Noise-equivalent power of 10 pW/√Hz and detectivity up to 10¹⁰ Jones.
- Thermal noise identified as the main limit on performance.
