(PhysOrg.com) -- In 1983, Richard Feynman proposed the idea of a machine that could create smaller scale replicas of itself. Today, such a system is still a challenge, but a machine that can produce nanometer-sized copies ...
(Phys.org) —A team of physicists working at Oxford University in the UK has found that it's possible to use some types of perovskite as a replacement for thin film silicon cells using the same basic processing technique ...
To make solar cells a competitive alternative to other renewable energy sources, researchers are investigating different alternatives. A step in the right direction is through new processes that change the surfaces of silicon ...
