The use of thinner substrates is an increasingly important way to reduce the price of crystalline solar cells. In this way, present industrial processes have to be suited, paying special attention to the relevance of the rear surface passivation for the new thicknesses. And in parallel, a clear revival of screen printing (SP) is being observed, bec...

Most commercial production of silicon solar cells uses phosphorus diffusion step for emitter formation, and Al alloying step for back surface field (BSF) formation. Phosphorus sources used by a majority of manufacturers are from a liquid source that is diffused in silicon using a tube diffusion furnace. This paper shows that new Phosphorus and Boro...

One of the key factors in the production of commercial crystalline silicon solar cells is to achieve a high-quality emitter by using simple in-line processing steps. Selective emitters (SE) can be fabricated by screenprinting high-and low-doped phosphorus pastes followed by diffusion in an infrared heated belt furnace, but also in one single screen...
