How does voltage output of a solar cell increase/decrease?

When I learnt about solar cells, I thought that voltage was constant or at least close to constant, but looking at I-V curves, voltage increases for some reason and I am not sure why. I saw a video that compared the voltage output of a solar cell at different resistors, which changed as the resistance changed, so is this why the voltage increases?
