According to Wikipedia "in the event of multiple exciton generation (MEG), quantum efficiencies of greater than 100% may be achieved since the incident photons have more than twice the band gap energy and can create two or more electron-hole pairs per incident photon." https://en.wikipedia.org/wiki/Quantum_efficiency https://en.wikipedia.org/wiki/Quantum_efficiency
Pretty fascinating!
- amluto 10y agoIn some sense, this is useless. A sensor that counts 50% of incoming photons twice each has more shot noise than a sensor that counts each photon once.
