Perovskite materials have excellent optical and electronic properties. The power conversion efficiency of perovskite solar cells has rapidly increased from 3.8% to 25.5% in laboratory settings. Efforts to further improve the efficiency of perovskite solar cells focus on composition tuning and morphology improvement of the perovskite absorption layer, energy level matching of the interface, and carrier extraction and transport rate in the transport layer. Various methods, such as additive engineering, defect passivation, interface engineering, and transmission material optimization, have been suggested.
Perovskite materials have outstanding optical and electronic properties. In recent years, the power conversion efficiency (PCE) of perovskite solar cells (PSCs) in the laboratory has raised rapidly from 3.8% to 25.5%. It has the potential to further improve the PCE of solar cells and approach the Shockley-Queisser (SQ) limit. For preparing high-efficiency PSCs, the chemical composition tuning and morphology improvement of the perovskite absorption layer, the energy level matching of the interface, the extraction and transport rate of carriers in the transport layer are focused widely. Many methods such as additive engineering, defect passivation, interface engineering, and transmission material optimization are suggested. This review summarizes efficiency improvement effort of perovskite solar cell from the three dimensions of perovskite absorption layer, charge transport layer and interface.
