Tackling the Challenges for Industrialization of Perovskite Silicon Tandem Solar Cells

Perovskite silicon tandem solar cells promise lower levelized costs of electricity than single junction silicon and perovskite solar cells. Achieving this goal requires high efficiencies >27% and stability for long device lifetime. Furthermore, deposition on textured silicon would enable higher energy yields, and lead-free perovskite absorbers would avoid acceptance issues due to environmental concerns. Applicability to different bottom solar cell concepts, such as PERC, TOPCon or SHJ, would further facilitate an evolutionary transition of the PV industry.
