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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
