The material was used by scientists in the U.S. in electrochemical cells which use electricity to separate steam into hydrogen and oxygen. The researchers say the oxide of perovskite used in the electrode improves cell performance and reduces operating temperatures.

The effect the coronavirus pandemic is having on energy systems and environmental policy in Europe was discussed at a recent machine learning and climate change workshop, along with the help artificial intelligence can offer to those planning electricity access in Africa.

Scientists in South Korea have worked with graphene and carbon nanotubes to develop a working lithium-ion battery that can be stretched by up to 50% without damage to any of the components. According to the scientists, the battery represents a significant step in the development of wearable or body-implantable electronic devices.

Analysts at Bloomberg New Energy Finance say the lowest-cost projects financed in Australia, China, Chile and the UAE in the last six months hit a levelized cost of energy of just $23-29/MWh and the best solar and wind projects will produce electricity for less than $20/MWh by 2030.

Scientists from Singapore have developed semi-transparent perovskite solar cells that can be easily integrated into a range of urban contexts, including building facades, gates and windows. The 21cm2 mini panels are made of perovskite solar cells based on methylammonium lead iodine (MAPbI3), with an efficiency of 20.28% for 0.16 cm2.

A study from Finland’s Lappeenranta University of Technology states decarbonization of desalination could help achieve a levelized cost of water of €0.32-1.66 per cubic meter. Solar and storage are expected to play a decisive role.

Researchers at the Queensland University of Technology have proposed a new design for a diamond nanothread bundle that could pave the way for a new form of mechanical storage. Pound-for-pound, the tech could be three times more powerful than lithium-ion batteries.

As a focus of research at leading institutes the world over, new developments in the perovskite field come thick and fast almost every week. From x-ray observations on a nanoscale to financing and plans for mass production, pv magazine is bringing together some of the most exciting developments of recent weeks.

The 11th edition of the German document which tracks solar price falls and efficiency improvements has considered the role bigger wafers are playing in cost reduction.

Russian researchers have improved the efficiency of a thin-fim GaAs‐based solar cell by 0.9% by applying single‐walled carbon nanotubes as the topmost layer. The cell also showed a slight increase in the short circuit current density, from 16.9 to 17.9 mA/cm2.
