The storage technology promises ten times the energy density offered by lithium-ion batteries but notorious cycling instability remains a concern. Researchers in South Korea may have come a step nearer a solution.
Scientists in the U.S. and South Korea have identified what could be a new route to high-efficiency perovskite-silicon tandem solar cells. Through engineering negatively charged particles in the passivation layer, the group made a tandem cell with 26.7% efficiency. With further tweaks to the silicon layer they expect to be able to surpass 30%.
Intersolar Europe is always a key date in the solar calendar but this year’s show had it all, including three panel-smuggling arrests. Elsewhere, wafers were getting bigger, efficiency records were tumbling and new technologies were emerging. There was also more news on the solar car ports fad and Hanwha’s ongoing legal tussle.
A research paper from scientists at the U.S. National Renewable Energy Laboratory outlines a new approach to the production of gallium arsenide based cells. The approach, termed ‘germanium on nothing’, could enable the cost effective, high volume production of PV cells based on III-V materials such as gallium arsenide.
A team of scientists from the Korea Advanced Institute of Science and Technology (KAIST) has proposed a gold-based halide perovskite as a material for high efficiency solar cells, which it says could be both more stable and more environmentally friendly to produce than many existing perovskites which scientists are investigating to boost solar efficiency.
