Studies on the influence of four different solvents on the morphology and photovoltaic
performance of bulk‐heterojunction films made of poly (3‐hexylthiophene)(P3HT) and [6, 6] …

Here, taking a polythiophene derivative (PBDD4T) as a starting polymer, we tried to increase
the rotation barrier and hence stabilize its backbone conformation by introducing fluorine …

Near Edge X-ray Absorption Fine Structure (NEXAFS) spectromicroscopy, resonant
scattering and resonant reflectivity are specialized, synchrotron radiation based, soft X-ray …

Photovoltaic energy conversion is arguably the most promising option for supplying
renewable, carbon-neutral energy on a global scale. In order to reach grid parity, however …
