Photovoltaic Responsivity (Ampere/Watt)
Posted: Sat Mar 29, 2014 12:30 am
Here's my favourite tech up for discussion, how many amperes can a black silicon pv cell possibly generate?
Please see para one, section "summary of invention" in the recently updated patent below. The last line mentions "up to 200 A/W". does that really mean a square meter of a sionyx pv cell can take 1.3kW of incident sunlight and convert it to like 200x1.3x1000 A ?
The mention of a variable reverse bias voltage from 0.1V to 15V points to a large span of photoresponsivity control, that must be useful for dynamically tuning photoresponsivity in low light as a photodetector. Wonder how that would work as a pv cell.
Did see a report once that said their PV cells improved absolute conversion efficiency by like 0.3% over a regular PV cell at 18%, which was kind of surprising as it felt there was something that didn't quite add up, maybe just in my understanding. They make the absolute best "day/night" vision equipment anyways, which i'd love to see in avionics too one day; sionyx.com
Feels like very high impact tech, with major work required for enforcing rightful use whenever avail able; thought it would be worthwhile to learn some more about it in the meanwhile
Thanks,
Rahul
