'Greener' way to assemble materials for solar applicationsMon, 05 Oct 2015 16:30:40 EDT
The efficiency of solar cells depends on precise engineering of polymers that assemble into films 1,000 times thinner than a human hair. Today, formation of that polymer assembly requires solvents that can harm the environment, but scientists have found a 'greener' way to control the assembly of photovoltaic polymers in water using a surfactant -- a detergent-like molecule -- as a template. Efficiency from larger perovskite solar cells improvedMon, 05 Oct 2015 13:28:51 EDT
Perovskite solar cells are cheaper to make than traditional silicon cells and their electricity conversion efficiency is improving rapidly. To be commercially viable, perovskite cells need to scale up from lab size. Researchers report a method for making perovskite cells larger while maintaining efficiency. Molecular nanoribbons as electronic highwaysMon, 05 Oct 2015 08:25:43 EDT
Physicists have developed a method to synthesize a unique and novel type of material which resembles a graphene nanoribbon but in molecular form. This material could be important for the further development of organic solar cells. Graphene as a front contact for silicon-perovskite tandem solar cellsFri, 02 Oct 2015 11:35:51 EDT
A team of researchers has developed an elegant process for coating fragile perovskite layers with graphene for the first time. Subsequent measurements show that the graphene layer is an ideal front contact in several respects. Organics energize solar cell researchThu, 01 Oct 2015 20:50:47 EDT
Scientists are using a new supercomputer to advance next-generation solar energy technologies by probing the functional interfaces found in organic and hybrid solar cells.
