Overview: In this study emitters diffused using an infrared (IR) lamp heated belt furnace are compared to emitters made with a POCl3 system. Emitter diffusion in an IR belt furnace was optimized in such a way that the results on multi-crystalline solar cells can compete with those for cells made using a POCl3 batch system. For solar cells made of long lifetime wafers selected from the top and middle of an ingot, the I-V parameters are the same for cells diffused with POCl3 and with IR.
