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 efficiency of (17.1 +/- 0.5)% on our BCB-SHJ solar cells. The main loss mechanisms affecting the fill factor and the V-OC are identified and are found to be avoided by minor process modifications. (C) 2012 Published by Elsevier Ltd. Selection and peer-review under responsibility of the scientific committee of the SiliconPV 2012 conference.
