An international team of researchers has developed a groundbreaking transparent solar cell that achieves a record-breaking efficiency of 12.3%.

From the article ...

Organic solar cells have lagged behind their silicon-based cousins for energy-producing purposes due to engineering challenges such as low efficiency and short lifespans, but recent work out of Forrest’s lab has achieved record efficiencies of 10% and estimated lifetimes of up to 30 years.

Another team has done the same in Denmark. I wonder how soon we will see these at consumer level for residential buildings?

This kind of stuff would be way simpler to install in non-residential buildings. And you still need a transformer / converter. Big windows better.
