研究目的
To develop an effective method, called glass rod-sliding and low pressure assisted solution processing composition engineering (GRS-LPASP), to manufacture high quality perovskite film in air for high-efficiency perovskite solar cells.
研究成果
GRS-LPASP composition engineering is a feasible method to prepare high-efficiency PSCs, achieving a maximum PCE of 19.78%. It also provides a potential method for the commercial production of PSCs.
研究不足
The GRS-Device had worse air atmosphere stability, which may be due to the larger fluctuation of GRS-Film surface on the macroscopic size, leading to the hole transport layer of uneven thickness and the worse isolation of water and oxygen, making the device decay faster.
1：Experimental Design and Method Selection:
The study employed GRS-LPASP composition engineering to manufacture high quality perovskite film in air.
2：Sample Selection and Data Sources:
(FAPbI3?xMACl)/DMF?NMP was used as precursor.
3：List of Experimental Equipment and Materials:
Glass rod, low pressure assisted solution processing equipment.
4：Experimental Procedures and Operational Workflow:
Perovskite precursor solution was dripped on the substrate and processed with GRS-LPASP.
5：Data Analysis Methods:
The performance of the perovskite solar cells was analyzed through J-V characteristics, IPCE spectrum, steady-state photoluminescence (PL), and transient photoluminescence measurements.
