Recent Research Progress on Lead-free or Less-lead Perovskite Solar Cells
International Journal of Electrochemical Science, 2017 Perovskite solar cells (PSCs) have been attracting great research interests and attained remarkable progress since its debut in 2009. Remarkably, the power conversion efficiency (PCE) of PSCs has already surpassed other types of solar cells that have ...

Whisker Test of Lead-Free Semiconductor Packages in Lead-Free Soldering
Journal of Japan Institute of Electronics Packaging, 2010 We evaluated the semiconductor mounting substrate and investigated the whisker's generations and factors by experimenting different environmental conditions. On the lead consisted of Cu base/Sn plating, the result of the condition 110°C/85% & 120°C/85% which were produced by Air-HAST (HAST with air) generates Sn whiskers faster than other high ...
