Elemental impurity risk management can help biomanufacturers to maintain regulatory alignment and ensure patient safety.

The FDA has changed its tune about the levels of a suspected carcinogen in Zantac and generic ranitidine drugs. Instead of just a little NDMA with a very low risk, the agency says its new “early, ...

Researchers from Zhejiang University in China have investigated the impact of impurities and defects on the performance of solar cells built with mono cast silicon (CM-Si) wafers and have found that ...

Defect states refer to electronic energy levels that arise from imperfections or irregularities in the crystal structure of materials, particularly in semiconductors and insulators. These ...

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 ...

“Traps” are places where an electron can be found "trapped" within a semiconductor. These traps are highly undesirable because they prevent electrons from moving around quickly so that they can be ...

Whether the discussion is about smart manufacturing or digital transformation, one of the biggest conversations in the semiconductor industry today centers on the tremendous amount of data fabs ...

Certain defects in silicon solar cells appear to improve their performance, according to research by scientists at the US government's National Renewable Energy Laboratory. Published yesterday in a ...

In a PVEL survey of 2018, light-induced degradation (LID, LeTID) was identified as the defect that causes the greatest concern among investors implying severe financial risks [1]. One reason is that ...

An international research team has investigated the impact of intrinsic point defects in selenium solar cells and has concluded that these defects are not responsible for voltage deficit. The ...
