Precipitation of CH3NH3PbCl3 in CH3NH3PbI3 and Its Impact on Modulated Charge Separation
, 2015 A precipitation of CH3NH3PbCl3 (MAPbCl3) in CH3NH3PbI3 (MAPbI3) has been observed for deposition from solutions containing CH3NH3I (MAI), PbCl2 and small amounts of ammoniumvaleric acid iodide (HOOC(CH2)4NH3I or AVAI) in N,N-dimethylformamide.

Stability, metastability and spectroscopic constants of electronic states of NH− and CH−
, 2015 Highly correlated ab initio methods were used in order to calculate potential energy curves (PECs) of the bound electronic states of CH− and NH− anions and the long-range parts of their excited states. The spin–orbit interaction between electronic states

Four-Terminal Tandem Solar Cells Using CH3NH3PbBr3 by Spectrum Splitting
, 2015 In this work, the use of a high bandgap perovskite solar cell in a spectrum splitting system is demonstrated. A remarkable energy conversion efficiency of 23.4% is achieved when a CH3NH3PbBr3 solar cell is coupled with a 22.7% efficient silicon ...

Brave New World: A Literature Review of Emerging Donors and the Changing Nature of Foreign Assistanc- Working Paper 273 [PDF]
In this paper, we look at the scale and scope of emerging donors, many of which are developing economies themselves. On the basis of a survey of the literature, we find that estimates of annual aid flows from new donors (so-called non-DAC donors) vary ...

Two Scaffolds from Two Flips: (α,β)/(β,γ) CH2/NH “Met-Im” Analogues of dTTP
, 2016 Novel α,β-CH2 and β,γ-NH (1a) or α,β-NH and β,γ-CH2 (1b) “Met-Im” dTTPs were synthesized via monodemethylation of triethyl-dimethyl phosphorimido-bisphosphonate synthons (4a, 4b), formed via a base-induced [1,3]-rearrangement of precursors (3a, 3b) in a ...
