Study on photovoltaic stability and performance by incorporating tetrabutyl phosphonium iodide into the active layer of a perovskite type photovoltaic cell

A simple synthesis of an ionic liquid is carried out using a trialkylphosphine and an alkyl halide. The results showed that the quality of perovskite crystals is enhanced by the incorporation of B4PI, when the percentage is 1.5% the PCE of champion PSCs MA98.5(B4PI)1.5PbI3 increases significantly from 15.5%, with a VOC of 0.957 mV, JSC of 23.6 mA cm-2, and an FF of 68.4%. Stability tests show that excess B4PI by 20% has a protective effect against humidity, MA80(B4PI)20PbI3 was more stable towards humidity, losing only 20% efficiency for 200 h.

Promoted Ruthenium Catalyzed Conversion of Syngas to Alcohols

This invention concerns a promoted catalyst system for making one or more alkanols from synthesis gas. The catalyst system contains a ruthenium compound and a halogen promoter dispersed in a low-melting tetraorganophosphonium salt. The halogen promoter is a compound capable of generating HX (where X═Cl, Br, or I) under reaction conditions. The invention also concerns a process for selectively preparing one or more alkanols from synthesis gas using the promoted catalyst system.
