Resumen

Planar perovskite solar cells using low-temperature atomic layer deposition (ALD) of the SnO₂ electron transporting layer (ETL), with excellent electron extraction and hole-blocking ability, offer significant advantages compared with high-temperature deposition methods. The optical, chemical, and electrical properties of the ALD SnO₂ layer and its influence on the device performance are investigated. It is found that surface passivation of SnO₂ is essential to reduce charge recombination at the perovskite and ETL interface and show that the fabricated planar perovskite solar cells exhibit high reproducibility, stability, and power conversion efficiency of 20%.
