Sno2 Thin Films

Perovskite solar cells were fabricated with SnO2 thin films as a window layer and electron transport layer by thermal evaporation. Fundamental characteristics of SnO2 thin films to determine the performance of solar cells were investigated in an optical and electrical manner, varying annealing temperatures. It is found the crystallinity and the presence of localized energy states play a key factor to control the properties of SnO2. In addition, XPS was used to confirm the stoichiometry of the SnO2 thin films, indicating a better charge collection on the annealed SnO2 samples. The SnO2 thin films annealed at 300 °C exhibited desirable optical and electrical properties for the enhanced performance of solar cells. The results show that thermally evaporated SnO2 thin films can be precisely engineered and controlled for mass production and more practical industrialization of perovskite solar cells.

Film Growth Rate

Recently, indium oxide (In2O3) thin films have emerged as a promising electron transport layer (ETL) for perovskite solar cells; however, solution-processed In2O3 ETL suffered from poor morphology, pinholes, and required annealing at high temperatures. This research aims to carry out and prepare pinhole-free, transparent, and highly conductive In2O3 thin films via atomic layer deposition (ALD) seizing efficiently as an ETL. In order to explore the growth-temperature-dependent properties of In2O3 thin film, it was fabricated by ALD using the triethyl indium (Et3In) precursor. The detail of the ALD process at 115–250 °C was studied through the film growth rate, crystal structure, morphology, composition, and optical and electrical properties. The film growth rate increased from 0.009 nm/cycle to 0.088 nm/cycle as the growth temperature rose from 115 °C to 250 °C. The film thickness was highly uniform, and the surface roughness was below 1.6 nm. Our results confirmed that film’s structural, optical and electrical properties directly depend on film growth temperature. Film grown at ≥ 200 °C exhibited a polycrystalline cubic structure with almost negligible carbon impurities. Finally, the device ALD-In2O3 film deposited at 250 °C exhibited a power conversion efficiency of 10.97% superior to other conditions and general SnO2 ETL.
