Key Milestones in Perovskite Solar Cell Efficiency

Perovskite solar cell efficiency has seen a remarkable increase over a short period, from initial low efficiencies to competitive levels, especially in tandem configurations.

The top 3

  1. Initial Breakthrough (2009): Perovskite solar cells were first reported in 2009 with an initial efficiency of approximately 3%, marking the beginning of their rapid development.
  2. Recent Single-Junction Record: In March 2026, Huarou PV achieved a certified 27.98% efficiency for a single-junction perovskite solar cell, setting a new benchmark for this category.
  3. Recent Tandem Cell Record: LONGi Solar announced a new world record of 35.5% efficiency for a crystalline silicon-perovskite tandem solar cell, certified in July 2026, showcasing the potential of multi-layer architectures.
