I wonder, what 'big questions' one can ask in the field of organic solar cells.
Alternatively, what are the major challenges? No matter if it is about physics, chemistry, processing, etc.
Usually HOPG is used for calibrating Kelvin probe tip work-function. However I found if operated in the air, HOPG surface will quickly adsorb air species and the measured contact potential drifts...

I want to calibrate the work-function of our Kelvin probe using HOPG as a reference sample. For the commonly used SPI HOPG, there are three grades, SPI-1, SPI-2 and SPI-3. Is there any difference...

I have been using the ultraviolet photoemission spectroscopy (UPS) to look at the energy levels of quantum dots. My quantum dot has a core/shell structure, where the shell is supposed to have a...

Most core/shell structured quantum dots (e.g. CdSe/CdZnS) today employ oleic acids as the passivating ligands. But can they be easily substituted for other types of organic ligands? Is there any...

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
