A joint research team has successfully identified, for the first time, the specific types of defects responsible for efficiency loss in silicon heterojunction (SHJ) solar cells.

Scientists used Lorentz transmission electron microscopy (LTEM) to visualize topological defects. They were able to do so by passing electrons and observing their deflections through a thin magnetic ...

A joint research team led by Dr. Hee-Eun Song of the Photovoltaics Research Department at the Korea Institute of Energy Research (President Yi ...

Korean researchers revealed that efficiency losses in heterojunction solar cells arise from two coexisting defect types - dangling bonds and weak silicon-silicon bonds. Their findings explain how ...

This paper reviews the research progress of layered double hydroxide (LDH) with various types of defects and its regulation strategies in recent years. Furthermore, the relationship between the ...

An atrial septal defect is a congenital heart issue. According to the Centers for Disease Control and Prevention (CDC), it develops in about 1 in 1,859 babies in the United States. An atrial septal ...

Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what ...

Defects in transistors, such as unwanted impurities and broken chemical bonds in the various layers of the semiconductor, can limit their performance and reliability. These defects are becoming harder ...

Several vendors are ramping up new inspection equipment based on infrared, optical, and X-ray technologies in an effort to reduce defects in current and future IC packages. While all of these ...
