A solar cell is basically a semiconductor, which converts sunlight into electricity, sandwiched between metal contacts that carry the electrical current.
Stacking two solar cells one over the other has advantages: Because the energy is "harvested" in two stages, and overall the sunlight can be converted to electricity more efficiently. Empa researchers have come up with a ...
Quantum process increases the number of electrons produced when light strikes a metal-dielectric interface
Researchers at MIT and elsewhere have found a way to significantly boost the energy that can be harnessed from sunlight, a finding that could lead to better solar cells or light detectors.
Scientists at the Energy Department's National Renewable Energy Laboratory (NREL) have demonstrated a way to significantly increase the efficiency of perovskite solar cells by reducing the amount of energy lost to heat.
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 is that while the solar ...
Silver nanowires hold promise for applications such as flexible displays and solar cells, but their susceptibility to damage from highly energetic UV radiation and harsh environmental conditions has limited their commercialization.
An international team of scientists have observed how a mysterious quantum phenomenon in organic molecules takes place in real time, which could aid in the development of highly efficient solar cells.
Engineers at Oregon State University have identified a new approach for the storage of concentrated solar thermal energy, to reduce its cost and make it more practical for wider use.
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have shown they can make flexible, transparent electrical conductors with record-high performance for use in solar cells, ...
