The key enabling device in a pixel is the photodiode, which produces an electric current when exposed to light.
The same photodiode is used also in solar panels to convert incident light to electric power. The photodiode in a camera pixel is used in the photoconductive mode
while in a solar cell it is used in the photovoltaic model. Nayar, working with research engineer Daniel Sims BS'14 and consultant Mikhail Fridberg of ADSP Consulting, used off-the-shelf components to fabricate an image sensor with 30x40 pixels.
each pixel's photodiode is operated always in the photovoltaic mode. The pixel design is very simple,
