(also known as long-read sequencing) a class of DNA sequencing methods which produce longer sequence reads, under active development since 2008.

Third-generation photovoltaic cells are solar cells that are potentially able to overcome the Shockley–Queisser limit of 31–41% power efficiency for single bandgap solar cells.
