NMR study of the nanomorphology in thin films of polymer blends used in organic PV devices: MDMO‐PPV/PCBM

TL;DR: In this article, solid-state NMR relaxometry has been evaluated as a complementary technique to traditional microscopic techniques like atomic force microscopy and transmission electron microscopy for the disclosure of the nanomorphology of thin films in organic solar cells.
Journal ArticleDOI

The impact of precursor water content on solution-processed organometal halide perovskite films and solar cells

TL;DR: In this article, the impact of the perovskite precursor's water content up to 10 vol% is investigated, in the form of a detailed study regarding the opto-electronic and morphological properties of the resulting films and devices.
Journal ArticleDOI

Aqueous chemical solution deposition of ferroelectric thin films

TL;DR: In this article, thin films of various ferroelectric multimetal oxides such as (Bi 1 m x La x ) 4 Ti 3 O 12 (BLT), SrBi 2 Ta 2 O 9 (SBT), and PbZr 1m x Ti x O 3 (PZT) have been prepared by an entirely aqueous chemi...
Journal ArticleDOI

Degradation of the Formamidinium Cation and the Quantification of the Formamidinium–Methylammonium Ratio in Lead Iodide Hybrid Perovskites by Nuclear Magnetic Resonance Spectroscopy

TL;DR: In this article, a nuclear magnetic resonance (NMR) spectroscopy protocol was introduced for the identification and differentiation of mixed perovskite phases and of a secondary phase due to formamidinium degradation.
Journal ArticleDOI

Improved thermal stability of bulk heterojunctions based on side-chain functionalized poly(3-alkylthiophene) copolymers and PCBM

TL;DR: In this paper, a combination of Bright Field Transmission Electron Microscopy (BFTEM) and the analysis of Selected Area Electron Diffraction (SAED) patterns revealed that the investigated preparation conditions do not really affect the thermal stability, whereas the introduction of a small ratio (10%) of specific functional moieties in the side chains of random P3AT copolymers does improve thermal stability significantly.
