Perovskite solar cells have been the subject of much research as the next generation of photovoltaic devices. However, many challenges remain to be overcome for the practical application. One of them ...

A South Korean research team has, for the first time, uncovered the molecular-level mechanism by which trace amounts of impurities—known as dopants—can reverse charge polarity in organic polymer ...

A recent article in Nature Communications introduced a method for precise p- and n-type substitutional doping of two-dimensional (2D) semiconductors. This method was applied for the one-step growth of ...

Voltage fade has quietly limited some of the most promising lithium-ion cathodes, eroding the energy they can deliver long ...

The epitaxial process is a well-established deposition technique in semiconductor fabrication because it enables the ability to achieve much higher doping concentrations than can be obtained via ion ...

Doping in semiconductors is adding a small amount of impurities into a very pure semiconductor material. It might sound strange to add impurities on purpose, but this is a critical to make ...

Scientists in Australia have looked at how gettering technologies could improve passivating contacts based on polysilicon and silicon monoxide (SiOx) for tunnel oxide passivated contact (TOPCon) solar ...

A p-n junction is an interface or boundary between p-type and n-type semiconductor materials within a single semiconductor crystal. The positive (p) side contains excess holes, while the negative (n) ...

(Nanowerk News) The carrier concentration and conductivity in p-type monovalent copper semiconductors can be significantly enhanced by adding alkali metal impurities, as shown recently by Tokyo Tech ...
