Abstract / Description of output

An array of pixels with dual functionality is
implemented in a deep trench isolation (DTI), backside
illuminated (BSI) process. Full thickness isolation
separates the diode from the readout and reconfiguration
transistors to make a 4T pixel. Each row of the array can
operate independently in imaging mode (IM) or energy
harvesting (EH) mode, ensuring power generation even
when capturing a frame. The theoretical limit for power
generation is evaluated based on an idealized lens and
realistic illumination levels for different spectra. The
presented chip achieves around half of this limit,
operating with an efficiency between 9-15%
