Abstract
A new concept for simple yet effective fabrication of high-efficiency Si solar cells is introduced. Based on the truncation of passivated elevations along the wafer surface, it is applicable for diffused- and induced-junction cells as well as for point contacts and line contacts. As an example, the `truncated-pyramid solar cell´ is discussed, which is characterized by small-area point contacts on top of pyramids whose tips have been removed
