The demand for clean renewable energy is increasing due to depleting fossil fuels and environmental concerns. Photocatalytic hydrogen production through water splitting is one such promising route to meet global energy ...
Aggregated Molecular Fluorophores in the Ammonothermal Synthesis of Carbon Dots
(
American Chemical Society
, 2017 , Article)
Recently, molecular fluorophores were shown to be formed in the bottom-up chemical synthesis, contributing to the emission of carbon dots (CDs), derived from a citric acid precursor. We applied an ammonothermal synthesis ...
Instability in CH3NH3PbI3 perovskite solar cells due to elemental migration and chemical composition changes
(
Nature Publishing Group
, 2017 , Article)
Organic-inorganic halide perovskites have rapidly grown as favorable materials for photovoltaic applications, but accomplishing long-term stability is still a major research problem. This work demonstrates a new insight ...
Photonics and fracture toughness of heterogeneous composite materials
(
Nature Publishing Group
