The study of chiral molecules – entities that exist in non-superimposable mirror images – has profound implications across a range of scientific disciplines, from synthetic chemistry to ...

Many semiconducting materials are possible candidates for solar cells. In recent years, perovskite semiconductors in particular have attracted attention, as they are both inexpensive and easy to ...

A German research group has used spectroscopic methods based on terahertz or microwave radiation and has discovered that they might help with more precise assessments of the characteristics and ...

The relationship between RF energy and assessing potential photovoltaic-material performance. The two overlapping ways to excite and measure PV materials such as perovskites. How the conflicting test ...
