Is the front of the solar cell connected to the negative electrode and the back to the positive elec

The front side of the solar cell is the positive electrode and the rear side is the negative electrode.

Solar cells are divided into two parts: the positive electrode (aluminum film) and the negative electrode (silver paste). The first is shiny silver and the second is black. When sunlight shines on the surface of the solar cell, electrons are released from the silicon atoms. Free electrons move between silicon atoms. Some electrons travel across the front side of the solar cell to the negative electrode and come into contact with the silver paste. of the negative electrode and connects to a circuit, generates current. As the electrons move toward the back of the solar cell, they contact the aluminum film of the positive electrode but do not connect to the circuit; no current is therefore generated.

Therefore, the front side of the solar cell is thepositive electrode and the back side is the negative electrode.

Positive money. According to inquiries about Juhe materials, we learned that Juhe materials are pure silver. Juhe Materials is a high-tech enterprise specializing in the research, development, production and sales of new electronic pastes. Its main products are silver faceplate pastes for solar cells. Frontal silver paste is a functional material based on silver powder. It is a key material for the preparation of metal electrodes for solar cells and represents 50 to 60% of non-silicon costs. Its product performance and preparation process are directly related to the photoelectric conversion efficiency of solar cells. In 2021, Juhe Materials ranked first in the world in Positive Silver Award product shipments, with a market share of 37.09%.
