Journal ArticleDOI
High aspect ratio silicon wire array photoelectrochemical cells.
James R. Maiolo,Brendan M. Kayes,Michael A. Filler,Morgan C. Putnam,Michael D. Kelzenberg,Harry A. Atwater,Nathan S. Lewis +6 more
TL;DR: Large photovoltages have been measured, and these values are significantly greater than those obtained from the substrate alone, demonstrating that significant energy conversion was occurring due to the absorption and charge-carrier transport in the vertically aligned Si wires.
Journal ArticleDOI
Thin-Film Materials for the Protection of Semiconducting Photoelectrodes in Solar-Fuel Generators
TL;DR: In this paper, the use of thin-layer protection strategies to enable semiconductor-based solar-driven fuel production is discussed and an outlook for the future development of thin layer protection strategies is provided.
Patent
Sensors for detecting analytes in fluids
Nathan S. Lewis,Erik J. Severin +1 more
TL;DR: In this article, an electronic nose for detecting an analyte in a fluid may be constructed by using such arrays in conjunction with an electrical measuring device electrically connected to the conductive elements of each sensor.
Journal ArticleDOI
Si microwire-array solar cells
Morgan C. Putnam,Shannon W. Boettcher,Michael D. Kelzenberg,Daniel B. Turner-Evans,Joshua M. Spurgeon,Emily L. Warren,Ryan M. Briggs,Nathan S. Lewis,Harry A. Atwater +8 more
TL;DR: In this paper, microwave-array solar cells with air mass 1.5 and fill factor > 65% have been fabricated using an active volume of Si equivalent to a 4 μm thick Si wafer, which exhibited opencircuit voltages of 500 mV, short-circuit current densities (Jsc) of up to 24 mA cm-2, and fill factors > 65%.
Journal ArticleDOI
The frontiers of energy
Robert C. Armstrong,Catherine Wolfram,Krijn P. de Jong,Robert Gross,Nathan S. Lewis,Brenda Boardman,Arthur J. Ragauskas,Karen Ehrhardt-Martinez,G. W. Crabtree,M. V. Ramana +9 more
TL;DR: In this article, ten leading experts in energy research share their vision of what challenges their respective fields need to address in the coming decades, from the search for better materials for fuels, to the design of energy policy and markets for the developing world.
