My question is basically how can a solar cell operate in forward bias? A normal diode in forward bias (with a battery connected) drives electrons from the N-side towards the pn junction where they are continuously recombining with holes (reducing the depletion zone and allowing for the flow of current). A solar cell seems less intuitive though. When in forward bias the electrons travel the opposite way. They go out the external cicuit which connects to the p-side, where the recombine with holes. It seems strange to me that both of these are essentially in "forward bias" however the electrons are esentially travelling the opposite way, similar to that of a diode in reverse bias.
