Indian researchers have proposed to build tandem solar cells based on a CIGS top cell and a bottom cell relying on a single-walled carbon nanotube (SWCNT) absorber. SWCNTs were previously used in ...

The image shows a cross-section of the active layers in the thin-film solar cell, with a total thickness of no more than 3 micrometres. Using nano-XRF measured at the MAX IV facility in Lund, it is ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

A group of scientists led by the University of Sydney has fabricated a tandem photovoltaic cell based on copper, indium, gallium and selenium (CIGS) thin-film technology and perovskite. The device ...

The new world record holder for producing electricity from CIGS solar cells is Uppsala University, with an efficiency of 23.64%. An impartial institute conducted the measurement, and the findings were ...

Improved contact layers helped boost the efficiency of the experimental CIGS-perovskite tandem cell to 24.6%. Image: HZB Researchers from the Helmholtz-Zentrum Berlin (HZB) and Humboldt University ...

KIER achieves world’s highest efficiency of 23.64% with flexible perovskite/CIGS thin-film tandem solar cell The Korea Institute of Energy Research (President Yi Chang-keun, hereinafter referred to as ...

Perovskites are promising materials for solar cells. A layer of dipolar molecules at the perovskite surface improves the efficiency of these devices. Read the paper: All-perovskite tandem solar cells ...

Researchers from Humboldt University Berlin and HZB have developed a tandem solar cell combining a perovskite-based top cell with a CIGS (copper, indium, gallium, and selenium) bottom cell. By ...
