\n\t\t\tMicroscopic wire has photovoltaic properties\t\t<\/h2>\n\t\t\n<\/header>\n\n\n\n
\n\n\n\t\t

Harvard chemists have built a new wire out of photosensitive materials that is hundreds of times smaller than a human hair. The wire not only carries electricity to be used in vanishingly small circuits, but generates power as well.<\/p>\n

Charles M. Lieber<\/a>, the Mark Hyman Jr. Professor of Chemistry, and colleagues created the nanowire out of three different kinds of silicon with different electrical properties. The silicon is wrapped in layers to create the wire. When light falls on the outer material, a process begins due to the interaction of the core with the shell layers, leading to the creation of electrical charges.<\/p>\n

The work was described in the Oct. 18 issue of the journal Nature.<\/p>\n

The idea of creating nanoscale photovoltaics is not new, Lieber said, but prior efforts used organic compounds in combination with semiconductor nanostructures that had lower efficiency and that degraded under concentrated sunlight. Lieber\u2019s materials have several advantages, he said. The materials are more efficient, converting 3.4 percent of the sunlight into electricity; they can withstand concentrated light without deteriorating, gaining efficiency up to about 5 percent; and they\u2019re as cheap to make as other related nanoscale photovoltaic devices.<\/p>\n

\u201cThe real is whether there\u2019s a new geometry that will lead to better photovoltaic technology,\u201d Lieber said. \u201cWe worked on coaxial geometry.\u201d<\/p>\n

The most recent development builds on Lieber\u2019s considerable prior work on nanoscale devices. He has developed sensors with potential bioterrorism applications that can detect a single virus or other particle, nanowire arrays that can detect signals in individual neurons, and a cracker-sized detector for cancer.<\/p>\n

A cheap nanoscale power source broadens the potential applications of such nanoscale devices. Though the tiny photovoltaic cells can generate enough electricity to power a similarly tiny circuit, Lieber said they\u2019re not yet efficient enough to have applications on the scale of commercial power generation. <\/p>\n

Commercial solar cells, he said, have efficiencies around 20 percent, compared with 3.4 percent for his nano-solar cells. One avenue of future research, Lieber said, will be to explore ways to boost efficiency of the nanowire photovoltaics. If they can reach 10 to 15 percent, he said, their lower cost of production \u2014 they can be made from relatively inexpensive materials and don\u2019t require clean rooms to produce \u2014 may make them useful in larger-scale applications.<\/p>\n

\u201cThere\u2019s no physical reason it couldn\u2019t be higher,\u201d Lieber said. \u201cI\u2019m pretty optimistic that we\u2019ll be able to track down the efficiency issue.\u201d<\/p>\n

Until then, Lieber sees a future for the nanowire photovoltaics in niche applications, such as multiple distributed sensors or durable, flexible devices, possibly sewn into clothing or worn as a patch.<\/p>\n

\u201cIt will have to be unique to be an economically viable application, some place where you want durability and flexibility, where if it gets destroyed, people don\u2019t care,\u201d Lieber said. <\/p>\n\n\n<\/div>\n\n\t\t","protected":false},"excerpt":{"rendered":"

The wire not only carries electricity to be used in vanishingly small circuits, but generates power as well.<\/p>\n<p><a title=\"\" href=\"http:\/\/harvardscience.harvard.edu\/node\/922\">Charles M. Lieber<\/a>, the Mark Hyman Jr. Professor of Chemistry, and colleagues created the nanowire out of three different kinds of silicon with different electrical properties. The silicon is wrapped in layers to create the wire. When light falls on the outer material, a process begins due to the interaction of the core with the shell layers, leading to the creation of electrical charges.<\/p>\n<p>The work was described in the Oct. 18 issue of the journal Nature.<\/p>\n<p>The idea of creating nanoscale photovoltaics is not new, Lieber said, but prior efforts used organic compounds in combination with semiconductor nanostructures that had lower efficiency and that degraded under concentrated sunlight. Lieber\u2019s materials have several advantages, he said. The materials are more efficient, converting 3.4 percent of the sunlight into electricity; they can withstand concentrated light without deteriorating, gaining efficiency up to about 5 percent; and they\u2019re as cheap to make as other related nanoscale photovoltaic devices.<\/p>\n<p>\u201cThe real is whether there\u2019s a new geometry that will lead to better photovoltaic technology,\u201d Lieber said. \u201cWe worked on coaxial geometry.\u201d<\/p>\n<p>The most recent development builds on Lieber\u2019s considerable prior work on nanoscale devices. He has developed sensors with potential bioterrorism applications that can detect a single virus or other particle, nanowire arrays that can detect signals in individual neurons, and a cracker-sized detector for cancer.<\/p>\n<p>A cheap nanoscale power source broadens the potential applications of such nanoscale devices.
