Smart phones are used worldwide due to their enhanced features, such as computing power, increased storage capacity, attractive interface, Wi-Fi connectivity and upload capabilities. These are personal, portable and being increasingly used to assist students' learning that creates new educational opportunities for students at university. Social media, on the other hand, has emerged in the last decade...
a-Si/a-Si tandem cells have a higher fill factor (FF), and lower light degradation than the single junction due to an intrinsic high electric field. Also, they are thinner and cheaper than a-Si single junction solar cells.[1] This paper presents experiment results of a-Si/a-Si tandem solar cells deposited by a High-Density Plasma Chemical Vapor Deposition (HDPCVD) and uses AMPS-1D to simulate the...
Emission microscopes have over a decade of continuous usage in inspection of semiconductors from the front surface for emission sites. The development of multilevel metallization, flip chip and lead-on-chip (LOC) package design has eliminated or restricted this inspection avenue. Inspection from the backside of semiconductors is complicated by a "silicon filter effect", in both short and...
