Producing electricity on the Moon at nightFri, 20 Dec 2013 11:34:34 EST
Scientists have proposed a system of mirrors, processed lunar soil and a heat engine to provide energy to vehicles and crew during the lunar night. This would preclude the need for batteries and nuclear power sources such as those used by the Chinese rover that recently landed on the moon. The lunar night lasts approximately 14 days, during which temperatures as low as -150 ºC have been recorded. This complicates vehicle movement and equipment functioning on the lunar surface, requiring the transport of heavy batteries from Earth or the use of nuclear energy, as exemplified by the Chinese rover Yutu. Graphene sees the light: Sheets of carbon just one atom thick could be used in photovoltaic cellsThu, 19 Dec 2013 15:44:44 EST
Sheets of carbon just one atom thick could make effective transparent electrodes in certain types of photovoltaic cells. Small size enhances charge transfer in quantum dotsMon, 16 Dec 2013 14:20:20 EST
Scientists show that shrinking the core of a quantum dot can enhance the ability of a surrounding polymer to extract electric charges generated in the dot by the absorption of light. Researchers split water into hydrogen, oxygen using light, nanoparticlesSun, 15 Dec 2013 16:09:09 EST
Researchers have found a catalyst that can quickly generate hydrogen from water using sunlight, potentially creating a clean and renewable source of energy. Their research involved the use of cobalt oxide nanoparticles to split water into hydrogen and oxygen. POPUP: Novel organic solar cellsFri, 13 Dec 2013 09:34:34 EST
Future solar cells will be light and mechanically flexible. They will be produced at low costs with the help of printing processes. Scientists aim at developing more efficient materials and new architectures for organic photovoltaic devices. They are working on improving the basic understanding and developing new architectures for semitransparent and non-transparent solar cells and modules.
