An all-perovskite tandem solar cell with extremely high efficiency and record-setting voltage has been developed.

Four terminal perovskite-silicon PV tandem devices hit 30% efficiency

Such a cell would turn more sunlight into electricity than either layer on its own, with better stability.

Solar panels aren't just for rooftops anymore.

The new solar cell is a lead-free low-dimensional perovskite material with a superlattice crystal structure—a first in the field.

Toward manufacturing semitransparent solar cells the size of windows

Researchers have developed a device that can generate electricity from thermal radiation based on similar technology to night-vision goggles.

Developed at Chalmers University of Technology, Sweden.

The setup is inexpensive and, in principle, could be incorporated within existing solar cells.

The team successfully increased the levels of energy absorbed by wafer-thin photovoltaic panels by 25%.

The scientists describe their technique in a paper published this month in the journal iSCIENCE.

Micro supercapacitors can increase the lifespan of batteries and reduce their charging time in products like smartphones and electric cars.
