TSMC certainly has the clout to do either solar cell related products or LED or both.
The solar business is still very capital intensive and may take longer to turn a profit as compared to LED lighting products. LED lighting is beginning to take off in a big way, and many channels exist for selling the chips to make them.
I would bet on LED lighting first.
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.
