Here, we reported the first solid-phase synthesis of metal-free perovskite crystalline materials. Using the optimized ball milling method, we found that the starting materials were fully converted to pure metal-free perovskite DABCO-NH 4 Br 3 (DABCO=N,N′-diazabicyclo [2.2.2] octonium) in ...

Yuanyuan Zhou 5 & Hongqiang Wang 1,2 Lithium salt-doped spiro-OMeTAD is widely used as a hole-transport layer (HTL) for high-efficiency n-i-p perovskite solar cells (PSCs), but unfortunately facing awkward instability for commercialization arising from the intrinsic Li+ migration and hygroscopi...
Such a perovskite structure exhibiting self-regenerative characteristic is named as an “intelligent” catalyst [11,12]. Sartipi et al. [3] studied the effect of the partial reduction of Pd from the bulk of LaCo0.95Pd0.05O3 perovskite structure onto its surface for the exhaust gas treatment. ...
Based on the newly developed ORR/OER/HER tri-functional catalyst from earth-abundant carbon materials, an integrated energy system was devised in which assembled perovskite solar cells were used for photoelectrochemical water splitting (OER and HER) to produce hydrogen and oxygen gases for fuel cells...
Noble metal materials are widely employed as benchmark electrocatalysts to achieve electrochemical water splitting which comprises of hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). However, the high cost and scarcity limit the wid
