Flash Infrared Annealing for Perovskite Solar Cell Processing

Perovskite solar cells prepared by flash evaporation.

A simple vacuum deposition method for the preparation of high quality hybrid organic-inorganic methylammonium lead iodide perovskite thin films is reported. When sandwiched in between organic charge transporting layers, such films lead to solar cells with a power conversion efficiency of 12.2%.

Annealing Effect on (FAPbI3)1−x(MAPbBr3)x Perovskite Films in Inverted-Type Perovskite Solar Cells

This study determines the effects of annealing treatment on the structure and the optical and electronic behaviors of the mixed (FAPbI₃)1-x(MAPbBr₃)x perovskite system. The experimental results reveal that (FAPbI₃)1-x(MAPbBr₃)x (x ~ 0.2) is an effective light-absorbing material for use in inverted planar perovskite solar cells owing to its large absorbance and tunable band gap. Therefore, good ...

Probing the Nature of Annealing Silicon Carbide Samples for Solar Cell

SiC powder preparation using Sol-Gel method. The size of nano-particles grows as the temperature exceeds 900° C. Size of probable agglomerations produced, is approximately less than 50nm. The surface is suitable to be used for dye solar cells. SiC emission occurs at wavelength area of 11.3μm or wave number area of 884.95 cm-1. In this paper probing the nature of annealed SiC samples in mixture,...

Effect of Annealing on Physical Properties of Cu2ZnSnS4 (CZTS) Thin Films for Solar Cell Applications

Cu2ZnSnS4 (CZTS) thin films were prepared by directly sputteringCu (In,Ga)Se2 quaternary target consisting of (Cu: 25%, Zn: 12.5%, Sn; 12.5%and S: 50%). The composition and structure of CZTS layers have beeninvestigated after annealing at 200 0C, 350 0C and 500 0C under vacuum. Theresults show that recrystallization of the CZTS thin film occurs and increasingthe grain size with a preferred orie...
