Abstract
We present the latest results of our back contact back silicon heterojunction (BCB-SHJ) solar cells with punctiform absorber contacts. We discuss the technological challenges and present a basic cell structure reaching an e_ciency of (17.1 _ 0.5)% on our BCB-SHJ solar cells. The main loss mechanisms a_ecting the fill factor and the VOC are identified and are found to be avoided by minor process modifications.
