6 FAQs about [Solar cell matching resistance calculation]

What causes series resistance in a solar cell?

Series resistance in a solar cell has three causes: firstly, the movement of current through the emitter and base of the solar cell; secondly, the contact resistance between the metal contact and the silicon; and finally the resistance of the top and rear metal contacts.
