Coating could lead to commercial lithium-metal batteries
A new coating developed by scientists at Stanford promises to bring lithium metal batteries ‘closer to reality’, by significantly extending their operational lifetime and limiting the occurrence of dendrites at the anode, which can cause short circuiting and fires.

PV cheaper than spot market electricity across Europe
The levelized cost of energy produced by large scale PV projects ranges from €24/MWh in southern Spain to €42/MWh in Finland. New research states that is already cheaper than the average spot market electricity price and that the figure for big facilities in southern Spain may fall to €14 in 2030 and €9 in 2050.

Canadian researchers have done the math on optimizing PV output
Mathematicians at Canada’s University of Waterloo who turned their attention to solar power have developed an algorithm they say offers better control over PV plant output. The researchers estimate the algorithm could improve the output of a 100 MW power plant by almost a million kilowatt-hours per year.

Scientists discover photovoltaic nanotubes
An international team of researchers led by the University of Tokyo has discovered a new material which, when rolled into a nanotube, generates an electric current if exposed to light. If magnified and scaled up, say the scientists, the technology could be used in future high-efficiency solar devices.
