Diverse causes behind frequency fluctuations in power grids

The use of renewables like the sun and wind can cause fluctuations in power grids. But what impact do these fluctuations have on security of supply? To answer this question, scientists from Juelich and Goettingen worked together ...

Standardizing perovskite aging measurements

Perovskite solar cells are an alternative to conventional silicon solar cells, and are poised to overtake the market with their high power-conversion efficiencies (over 22% now) and lower capital expenditure and manufacturing ...

Cleaner, cheaper hydrogen from methane

Researchers from the Institute of Chemical Technology (ITQ), Valencia's Polytechnic University (UPV) and the Superior Council of Scientific Investigations (CSIC) have developed ceramic membranes that make it possible to produce ...

Transparent solar technology represents 'wave of the future'

See-through solar materials that can be applied to windows represent a massive source of untapped energy and could harvest as much power as bigger, bulkier rooftop solar units, scientists report today in Nature Energy.

A solar cell you can put in the wash

Scientists from RIKEN and the University of Tokyo have developed a new type of ultra-thin photovoltaic device, coated on both sides with stretchable and waterproof films, which can continue to provide electricity from sunlight ...
