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.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
