Hey! Today I want to experience a homemade solar panel
How much this method works, and how many volts, amperes this homemade solar panel gives out, you will learn from this video.

Energy is generated when the sun's rays hit the semiconductor and heat it up. As a result, electrons are released inside the semiconductor. Under the influence of an electric field, electrons begin to move in a more orderly manner, which leads to the appearance of an electric current.

A semiconductor is a material in which atoms either have extra electrons (n-type) or not enough (p-type). That is, a semiconductor consists of two layers with different conductivity.

An n-layer is used as a cathode in this scheme. The p-layer is the anode. That is, electrons from the first layer can transfer to the second. The transition occurs due to knocking out electrons by photons of light. One photon knocks out one electron. After that, passing through the accumulator, they fall back into the n-layer and everything goes in a circle.
