Solar charged supercap driving LED schematic
Hi! Im trying to create a very simple circuit that charges a supercap (say 2.7V 1F) from a small solar cell (1.67V at Pmpp). When pressing the button the supercap should be disconnected from the solar cell and connected to the LED instead. Would this work? What are the potential issues with this approach? I want the LED to be ideally green or white but i'm afraid i'm gonna have a hard time finding something in that color that lights up at such low voltage. I probably can get rid of R1 altogether. I am trying to minimize the number of parts and keep it relatively simple. Since i'm a beginer i dont wanna get in over my head. Thanks for the help! Have a great new year!
