Perovskite oxide BaSnO3 with high electron mobility and a perovskite structure was first used as an electron-transporting layer in perovskite solar cells. After optimization, the resulting mp-BSO device can perform as well as the mp-TiO2 one and even better.

Abstract The requirements of electron transport layer (ETL) for high efficiency Perovskite solar cells (PSCs) are, for example, appropriate band energy alignment, high electron mobility, high optical transmittance, high stability, and easy processing. SnO2 has attracted more attention as ETL for PSCs because it has diverse advantages, e.g., wide bandgap energy, excellent optical and chemical stability, high transparency, high electron mobility, and easy preparation. The SnO2 ETL was fabricated by RF magnetron sputtering technique to ensure the chemical composition and uniform layer thickness when compared to the use of chemical solution via spin-coating method. The RF power was varied from 60 - 150 W. The Ar sputtering gas pressure was varied from 1 × 10−3 - 6 × 10−3 mbar while keeping O2 partial pressure at 1 × 10−4 mbar. The thickness of SnO2 layer decreases as the Ar gas pressure increases resulting in the increase of sheet resistance. The surface morphology and optical transmission of the SnO2 ETL were investigated. It was found that the optimum thickness of SnO2 layer was approximately 35 - 40 nm. The best device shows Jsc = 27.4 mA/cm2, Voc = 1.03 V, fill factor = 0.63, and efficiency = 17.7%.

A–D–A small molecule acceptors possess strong absorption in the visible or NIR region, low bandgaps, relatively high electron mobility and proper miscibility with donors, which enables the achievement of high power conversion efficiency for organic solar cells based on these molecules.

A thickness insensitive water/alcohol soluble small molecular, PN6, exhibits high electron mobility with deep LUMO energy level, and effectively decrease the work function of the cathode. Those properties significantly enhance the power conversion efficiency from 8.73% (control cell) to 17.27%.
