Update: reduced total number of diodes, using high value ideal diodes (same as part 2)
What if I told you, Zener diodes are the answer to all our energy crises? Run at 1s/s simulation speed to recharge quickly.
Built-in potential is developed in a P-N junction due to diffusion of carriers across the junction upon joining the layers. Here this diffusion current is capitalized as the power source. Practically, this might require about 10E15 diodes. Plus one if you use an LED
