Appraisement of Crystal Expansion in CH 3 NH 3 PbI 3 on Doping: Improved Photovoltaic Properties

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...

Chloride Incorporation Process in CH₃NH₃PbI(3-x)Cl(x) Perovskites via Nanoscale Bandgap Maps.

CH3NH3PbI(3-x)Cl(x) perovskites enable fabrication of highly efficient solar cells. Chloride ions benefit the morphology, carrier diffusion length, and stability of perovskite films; however, whether those benefits stem from the presence of Cl(-) in the precursor solution or from their incorporation in annealed films is debated. In this work, the photothermal-induced resonance, an in situ techn...

Crystal structure of AI ( tBu ) 3 ( NH 2 CH 2 CH 2 Ph ) : A molecular " slinky "

The molecular structure of AI(tBu)3(NH2CH2CHzPh) is determined by the crystal packing of the phenyl rings and the pseudo spherical Al(tBu)3 units, and may be viewed as a layered structure consisting of double sheets of the phenyl rings and the Al(tBu)3 units. The A1-N-C-C linkage shows severe disorder as a result of its flexibility. The structure of Al(tBu)3 (NH2CH2CH2Ph) can be likened to a mo...

Chiral molecule formation in interstellar ice analogs: alpha-aminoethanol NH 2 CH(CH 3 )OH

Aims. Aminoalcohol molecules such as alpha-aminoethanol NH2CH(CH3)OH may be aminoacid precursors. We attempt to characterize and detect this kind of molecules which is important to establish a possible link between interstellar molecules and life as we know it on Earth. Methods. We use Fourier transform infrared (FTIR) spectroscopy and mass spectrometry to study the formation of alphaaminoethan...
