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!
EDIT: I got featured on Hackaday.com!
Hello,
ReplyDeleteI got 21mV from an OA90 (Ge). Got more "power" from LED's
See the experiment at: http://speakyssb.blogspot.pt/2011/12/powered-by-leds.html and http://speakyssb.blogspot.pt/2011/12/powered-by-leds-ii.html
Good luck!
Nice experiment!
ReplyDeleteI´m getting more than 2v from LED´s, but is a low current. I, will post as soon a Buy a new voltimeter... :p someone has stolen it
ReplyDeleteSolar cell! nice and interesting. I got one solar cell from MyDeals247.com for bets deal
ReplyDeleteYour information is very nice. I have related information.... solar pv
