photoelectric effect in 1921 was definitely not blue-sky research with no practical applications; it was one of the core problems in physics at the time.

What were the specific "practical" problems that investigating and figuring it out that were solved?

photomultiplier tubes. At the time the effect was discovered, PE was recognized experimentally (and exploited), but unexplained, and once it was, development of PMTs (critical to a wide range of practical technologies) was greatly sped up. This led to high quality television cameras not long after...
