New perovskite solar cell design could outperform existing commercial technologies, Stanford and Oxford scientists report

A new design for solar cells that uses inexpensive, commonly available materials could rival and even outperform conventional cells made of silicon.Writing in the Oct. 21 edition of Science, researchers from Stanford and Oxford describe using tin and other abundant elements to create novel forms of perovskite – a photovoltaic crystalline material that’s thinner, more flexible and easier to manufacture than silicon crystals.

Aluminum-ion battery technology advances

A new high-performance 'aluminum-ion' battery could be the technical breakthrough needed to boost the renewable energy takeover. It's safe, uses abundant low-cost materials, recharges in one minute and withstands many thousands of recharge cycles.If this new battery lives up to expectations, it could propel a whole new chapter in the renewable takeover of the world's energy supply.Stanford University scientists have invented the first high-performance aluminum battery that's fast-charging, long-lasting, inexpensive - and safe.
