Breakthrough material could lead to cheaper, more widespread solar panels and electronics
Organic semiconductors have the potential to make electronics and solar panels much easier to generate. A big problem, though, is that the freely moving electrons in the semiconductors are hard to generate. A few researchers have done experiments, and have made strides in making it easier to generate free electrons in organic semiconductors. They achieved it by connecting the organic semiconductors to a single layer of a different semiconductor. If related experiments continue to succeed, many strides will be made with solar panels.
- In the world of the near future it may be viable to actually print out an electronic device, or paint a solar panel right onto a wall.
- The seemingly sci-fi substance that could make such actions possible are called organic semiconductors, which are themselves comprised of molecules or polymers.
- Unfortunately, these substances so far have generally contained a bound, or not free electron, which has caused delays in instituting their widespread commercial use.
“The discovery was made by combining two highly complementary experimental tools based on ultrafast lasers, time-resolved photoemission spectroscopy in Chan’s lab and transient optical absorption in Zhao’s lab.”
