Open Circuit Voltage Photodetector
TS-065426 — Photodetectors are devices that detect light and convert it into an electrical signal. They operate based on the photoelectric effect, in which photons (light particles) strike the semiconductor material, creating electron-hole pairs that lead to the flow of electrical current that can be measured.
Existing photodetectors are susceptible to various noise sources, such as thermal and electronic. The noise can degrade the signal-to-noise ratio and affect the accuracy of measurements, particularly in low-light conditions. This technology is an open-circuit voltage photodetector (OCVP) that…
