Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current. That mismatch has bothered solar researchers for more than a decade. Silicon ...

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at ...

α-FAPbI 3, a promising solar cell material with a cubic perovskite structure that is metastable at room temperature, can be stabilized by introducing a pseudo-halide ion like thiocyanate (SCN –) into ...

Lead halide perovskite nanocrystals (PeNCs) have attracted extensive attention due to their high photoluminescence quantum yield (PLQY), adjustable bandgap, low cost, and excellent photoelectric ...

A milestone in graphene research: Chemists have succeeded in controlling the passage of halide ions by deliberately introducing defects into a two-layer nanographene system. Their paper shows new ...

A group of researchers led by the Chung-Ang University in South Korea has designed a tin halide perovskite (Sn-HP) solar cell that utilizes an additive known as 4-Phenylthiosemicarbazide (4PTSC) to ...

An international research team built the triple-junction device with dual bulk and interface passivation technique aimed at promoting halide homogeneity at the interface between the perovskite ...

The formula for a perovskite compound is typically expressed as ABX3. These are crystalline structures that bond two cations ("A" and "B", divalent metal ion) to an anion ("X"); the "B" atoms tend to ...
