So the other day while i was studying about solar cells, i realized that a photovoltiac solar cell is very similar to a standard silicon diode, they are both p-n junctions, the only difference being that a solar cell has a higher surface area. So i decided to use an 1N4148 standard small signal rectifier with an exposed die. I connected it to a Multimeter to check the voltage coming out of the diode. To my surprise, it worked! After concentrating the light to the diode with a magnifying glass, i was a able to get a usable voltage from the diode
Please feel free to give any suggestions and improvements in the comments
Thank for watching!
