Recap - Solar Cell

Part of the Optics, Waves and Modern Physics section of Coddy's Physics journey. Lesson 39 of 53.

Challenge

A small lamp shines 0.5 W of 600 nm light onto a light sensor. One photon in ten frees an electron that makes it into the circuit (η = 0.1). First find how many photons N arrive each second, then the current I in the sensor, in mA.
