Perovskite solar cell efficiency has shown remarkable progress since their inception in 2009. Here’s a chronological breakdown of key milestones:
2009–2011: Initial development
The first perovskite solar cells, developed by Tsutomu Miyasaka’s team, achieved 3.8% efficiency using a dye-sensitized architecture. By 2011, 6.5% efficiency was reached through improved designs.
2012–2015: Solid-state breakthrough
A pivotal shift occurred in 2012 when researchers replaced liquid electrolytes with solid-state hole transporters (e.g., spiro-OMeTAD), enabling >10% efficiency. This innovation spurred rapid advancements, with certified efficiencies reaching 12.3% by 2015 using redox shuttles.
2016–2021: Record-setting growth
Efficiency surged to 25.7% for single-junction cells by 2021. Tandem architectures combining perovskite and silicon achieved 29.8% efficiency, surpassing standalone silicon cells. Current thin-film perovskite cells alone reach 29.15% in lab settings, outperforming other thin-film technologies like CIGS (23.4%) and CdTe (22.1%).
Stability advancements
Recent developments include cells maintaining 80% efficiency for over 5 years, addressing earlier durability concerns. This progress positions perovskites as a viable commercial competitor to silicon-based photovoltaics.
