Single Crystalline Tin based Nanocomposites: Cation-Controlled Synthesis and Their Application to Low Temperature Processed Inorganic-Organic Hybrid Perovskite Solar Cells |
| 초록 |
TiO2 as an electron transport layer restrict the ultimate use for high efficiency PSCs with long-term stability due to its inferior light stability and optical/electrical property. Here, we report one-pot synthesis strategy for preparing a single crystalline Sn-based nanocomposite (SCSC) as an alternative to TiO2 ETL. The controlling cation ratio (Zn/Sn) with hydrazine results in the formation of various types of Sn-based materials, i.e., spherical type SnO2 and Zn2SnO4 nanoparticles (NPs), SnO2 nanorod, and Zn2SnO4 nanocube, nanocomposite composed of single crystalline SnO2 nanorods and Zn2SnO4 nanocubes (SCSC). Through the controlled experiments, the detailed synthesis mechanism is further proposed. To demonstrate merits of the SCSC as an ETL in PSCs, we fabricate the PSCs through low temperature process below 150 oC and evaluate its photovoltaic performance. Compared with other Sn-based counterparts, SCSC-based PSC shows the most outstanding device performance exceeding 17 %. |
