When visiting California's central valley in the summertime, it's hard to imagine that solar energy isn't single-handedly meeting the west coast's energy needs. But one problem with modern solar cells ...

Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps). Different colors have different energies, and no single semiconductor has a ...

Intermediate band quantum dot solar cells (IB QD SCs) represent an advanced photovoltaic architecture designed to exceed the Shockley–Queisser limit by harvesting sub-bandgap photons. In these devices ...

Researchers in Spain have analyzed the most important technologies for the development of intermediate-band solar cells (IBSC), a solar PV technology that was conceived to exceed the Shockley–Queisser ...
