چکیده
The ambient fabrication temperature inside the glove box is found to play an important role in determining overall power conversion efficiency solar cells based on CH3NH3PbI3 (MAPI) hybrid organic-inorganic perovskites. We find that a variation of only 10 °C during process has crucial impact both reproducibility and devices. Atomic Force Microscopy, XRD, UV-Vis absorption spectroscopy, electroluminescence studies have been carried out investigate origin this behavior. conclude partial vapor pressure solvent impacts crystallization process, inducing increased density traps within bandgap perovskite.

CH(3)NH(3)PbI(3) perovskite / silicon tandem solar cells: characterization based optical simulations.
In this study we analyze and discuss the optical properties of various tandem architectures: mechanically stacked (four-terminal) and monolithically integrated (two-terminal) tandem devices, consisting of a methyl ammonium lead triiodide (CH(3)NH(3)PbI(3)) perovskite top solar cell and a crystalline silicon bottom solar cell. We provide layer thickness optimization guidelines and give estimates...

می توان گفت واقعیت چند لایه ا ی کلاس های زبان انگلیسی بسیار حائز اهمیت است، زیرا عواطف و بینش های زبان آموزان تحت تاثیر قرار می گیرد. در پژوهش پیش رو، گفته می شود که دبیران با در پیش گرفتن رویکرد فرا-انسانگرایی ، قادرند در زندگی دانش آموزانشان نقش مهمی را ایفا سازند. بر اساس گفته ی ویلیامز و بردن (2000)، برای کرل راجرز، یکی از بنیان گذاران رویکرد انسانگرایی ، یادگیری بر مبنای تجربه، نوعی از یاد...
Using Low Temperature Photoluminescence Spectroscopy to Investigate CH₃NH₃PbI₃ Hybrid Perovskite Degradation.
Investigating the stability and evaluating the quality of the CH₃NH₃PbI₃ perovskite structures is quite critical both to the design and fabrication of high-performance perovskite devices and to fundamental studies of the photophysics of the excitons. In particular, it is known that, under ambient conditions, CH₃NH₃PbI₃ degrades producing some PbI₂. We show here that low temperature Photolumines...
