Intermediate reflector layers are commonly used for light man‐agement purposes in multi‐junction silicon based devices containing a‐Si:H top‐ and µc‐Si:H bottom‐sub‐cells. A low resistance of such layers can have a severe impact on the solar module performance due to shunting of the bottom sub‐cell by the P2 scribe. A common solution for this problem is the use of an additional scribe line. However, not only the additional processing step is disadvantageous but also the dead area losses are increased as well by the additional scribe. This work introduces a novel solar cell stripe interconnection scheme that requires only three scribing processes with similar dead area losses as they would be apparent in the standard interconnection scheme. An implementation to mini modules shows no negative impact on the electrical properties and simultaneously reducing the required number of scribing steps. (© 2015 WILEY‐VCH Verlag GmbH &Co.
