Theoretical conversion eff. limit for CIGS thin film, as predicted by NREL of DOE ( Boulder, CO ), is as high as 18 % ( as compared to 24 % for single xtal Si ) but only up to 16 % has been demonstrated so far in lab samples.
Because it has 4 components and separates into many quasi-stable phases depending on processing, CIGS thin film is a notoriously difficult material to control and shows variation in conversion eff. Many US companies have been struggling with this for years.
What I would like to know is what sort of production rate and yield TSMC is managing to get at their Pilot Line.
Otherwise this report is just PR flak.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
