Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Transparent electrode is a key component in the multi‐junction solar cells, working as window and intermediate electrodes. It requires high transparency for wide range and suitable electrical junctions. Graphene, a single atomic layer of sp² graphitic carbon, is one of alternative materials. We demonstrated a‐Si thin film solar cells with high‐quality graphene grown by chemical vapor deposition. The graphene‐cell showed higher open‐circuit voltage compared with conventional transparent conductive oxide. It might be a contribution of lower Schottky barrier at graphene/p‐layer interface. Our experimental results demonstrated a high potential of graphene transparent electrode not only for a‐Si solar cells but also for multi‐junction solar cells.</p> </abstract>
