What is a half-cut cell?

A solar panel (solar module) consists of what is called a cell (power generation element). A half-cut cell is a cell that is half the size of the conventional one.
The half-cut cell is about half the size of a normal cell, and it is said that power generation efficiency is improved by reducing the electrical resistance. Even in the hot summer months, it is possible to prevent a drop in conversion efficiency due to high temperatures, and it can be expected to generate power more efficiently.
