The photovoltaic process inside a solar cell can be described using the distribution of electrostatic potential in the material. In this paper. the magnitude of the electrostatic potential of the solar cell for the p-i-n junction type is analyzed as the built in potential due to the diffusion activity of electrons and holes. The magnitude of the electrostatic potential is obtained by ... https://cosmeticssquadets.shop/product-category/boosting-serum/
