<p>A silicon solar cell is formed with an N-type silicon layer on a P-type silicon semiconductor substrate. An antireflective and passivation layer is deposited on the N-type silicon layer, and then an aluminum ink composition is printed on the back of the silicon wafer to form the back contact electrode. The back contact electrode is sintered to produce an ohmic contact between the electrode and the P-type silicon layer. The aluminum ink composition may include aluminum powders, a vehicle, an inorganic polymer, and a dispersant. Other electrodes on the solar cell can be produced in a similar manner with the aluminum ink composition.</p>
