Photovoltaic cells made from materials with a greater band ... On the p-side next to the junction there will, therefore, be no electrons, (since they are immediately taken to the n-side) so electrons will come from a little farther in the area to cover their voids. This current is called diffusion current. In the same way, it happens with the holes, minority carriers on the n-side. The above ...
