Record-Breaking Solar Cells

Developed by Singapore's Nanyang Technological University (NTU) and A*STAR Institute of Microelectronics (IME), new thin-film silicon solar cells are designed to be made from cheaper, low-grade silicon. The nano-structured solar cells can produce a current of 34.3mA/cm2 – a world record for a silicon solar cell of its kind.

Novel Catalyst Helps Turn Carbon Dioxide Into Fuel

Artificial photosynthesis is the process of converting carbon dioxide gas into useful carbon-based chemicals - most notably fuel or other compounds usually derived from petroleum - as an alternative to extracting them from biomass. An Illinois research team has produced a catalyst that improves the process.
