In particular, perovskite solar cells made from lead halide
materials (APb[X.sub.3]) have enjoyed rapid development, with measured power conversion efficiencies rivaling state-of-the-art silicon devices [4-7].
It includes two experimental articles, one shedding some light on photo-reflectance measurements when probing above the pump beam energy and the other discussing morphology in hybrid lead halide
perovskite solar cells.
Firstly, the stability of the organic lead halide perovskite is greatly affected by external environmental factors (such as humidity, temperature, and ultraviolet radiation), which lead to the low stability of the devices and the great difficulties in encapsulating cells in the later stage.

- Lead halide
as radiant agent in High Intensity Discharge (HID) lamps used for professional reprography applications;
Organic-inorganic lead halide perovskite materials have been attracting increasing attention due to the soaring solar-to-electric power conversion efficiency [1-4].
Recent work indicates that mixed-cation lead halide perovskites, in which small methyl ammonium (MA) cation and another bulkier organic ammonium cation are used, can lead to various intriguing properties.
