Tantalate-based Perovskite for Solar Energy Applications
To realize a sustainable society in the near future, the development of clean, renewable, cheap and sustainable resources and the remediation of environmental pollutions using solar energy as the driving force would be important. During the past few decades, plen‐ ty of efforts have been focused on this area to develop solar light active materials to meet the increased energy and environmental ...
متن کاملMonovalent Cation Doping of CH3NH3PbI3 for Efficient Perovskite Solar Cells
Here, we demonstrate the incorporation of monovalent cation additives into CH3NH3PbI3 perovskite in order to adjust the optical, excitonic, and electrical properties. The possibility of doping was investigated by adding monovalent cation halides with similar ionic radii to Pb2+, including Cu+, Na+, and Ag+. A shift in the Fermi level and a remarkable decrease of sub-bandgap optical absorption, ...
متن کاملControlled reaction for improved CH3NH3PbI3 transition in perovskite solar cells.
Hybrid halide perovskites represent one of the most promising solutions toward the fabrication of all solid nanostructured solar cells, with improved efficiency and long-term stability. This article aims at investigating the properties of CH3NH3PbI3 with controlled loading time in CH3NH3I solution via a two-step sequential deposition and correlating them with their photovoltaic performances. It...
متن کاملAlkali Metal Doping for Improved CH3NH3PbI3 Perovskite Solar Cells
Organic-inorganic hybrid halide perovskites are proven to be a promising semiconductor material as the absorber layer of solar cells. However, the perovskite films always suffer from nonuniform coverage or high trap state density due to the polycrystalline characteristics, which degrade the photoelectric properties of thin films. Herein, the alkali metal ions which are stable against oxidation ...
متن کاملFabrication and Characterization of CH3NH3PbI3-x-yBrxCly Perovskite Solar Cells
Fabrication and characterization of CH3NH3PbI3 ́x ́yBrxCly perovskite solar cells using mesoporous TiO2 as electron transporting layer and 2,21,7,71-tetrakis-(N,N-di-4-methoxypheny lamino)-9,91-spirobifluorene as a hole-transporting layer (HTL) were performed. The purpose of the present study is to investigate role of halogen doping using iodine (I), bromine (Br) and chlorine (Cl) compounds as do...
