Crystalline Silicon Solar Cells | SpringerLink
A high-efficiency low-resistance silicon solar cell (RESC) is a solar cell developed with melted silicon exhibiting a resistivity of 0.2 and 0.3 Ω cm in the p-type region. The major feature is to make a passivation layer at the emitter of the cell; as a result, the surface recombination rate of the photogenerated carriers on the surface can be ...
