Perovskite solar cells (PSCs) have rapidly emerged as a highly promising photovoltaic technology, demonstrating remarkable power conversion efficiencies and potential for low-cost manufacturing. A critical aspect of optimizing PSC performance lies in the careful selection and implementation of functional materials, particularly within the charge transport layers. Lithium Bis(trifluoromethanesulfonyl)imide (Li TFSI), identified by CAS No. 90076-65-6, has proven to be an effective additive in this domain, acting as a p-dopant to significantly improve cell efficiency. As a specialized chemical supplier, we offer high-purity Li TFSI to support ongoing research and commercialization efforts in perovskite solar technology.

In perovskite solar cells, the hole transport layer (HTL) is crucial for efficiently extracting holes generated in the perovskite absorber layer and transporting them to the electrode. Spiro-OMeTAD is a widely used HTL material, but its intrinsic conductivity and hole mobility can sometimes limit the overall performance of the solar cell. This is where Li TFSI demonstrates its value. When used as a p-dopant, Li TFSI enhances the conductivity and hole mobility of Spiro-OMeTAD. This doping process creates more charge carriers and facilitates their movement, leading to a substantial increase in short-circuit current (Jsc) and overall power conversion efficiency (PCE).

Research has shown that the inclusion of Li TFSI in the HTL can lead to more stable and efficient perovskite solar cells. Its hydrophilic nature and chemical structure contribute to effective doping without significantly compromising the structural integrity or long-term stability of the device. The precise mechanism involves Li TFSI facilitating the oxidation of Spiro-OMeTAD, creating positively charged species that enhance conductivity. For researchers and manufacturers in the solar energy sector, acquiring a consistent and high-quality source of Li TFSI is paramount for reproducible results and scalable production.
