Challenges and prospects of very thin (<50 μm) crystalline silicon solar cells

Abstract

Thin crystalline silicon (c-Si) solar cells are highly attractive not only for reducing the material cost but also for realizing light-weight and flexible PV modules. Amorphous silicon/c-Si heterojunction (SHJ) architecture is suited to thin c-Si cells because of its excellent surface passivation capability. In this paper, we discuss the potential of very thin c-Si cells using the SHJ architecture.
