How a Solar Cell Works. Solar cells contain a material that conducts electricity only when energy is provided—by sunlight, in this case. This material is called a semiconductor; the "semi" means its electrical conductivity is less than that of a metal but more than an insulator''s. When the semiconductor is exposed to sunlight, it ...
Learn MoreCompared with the conventional solar cell, the short-circuit current can be increased by about 7%; 2) Both positive and negative electrodes are on the back of the cell, so it is unnecessary to consider the grid line occlusion problem, and the grid line proportion can be properly widened, so as to reduce the series resistance; ...
