Journal ArticleDOI
Solar Water Splitting Cells
Michael G. Walter,Emily L. Warren,James R. McKone,Shannon W. Boettcher,Qixi Mi,Elizabeth A. Santori,Nathan S. Lewis +6 more
TL;DR: The biggest challenge is whether or not the goals need to be met to fully utilize solar energy for the global energy demand can be met in a costeffective way on the terawatt scale.
Journal ArticleDOI
Enhanced absorption and carrier collection in Si wire arrays for photovoltaic applications
Michael D. Kelzenberg,Shannon W. Boettcher,Jan Petykiewicz,Daniel B. Turner-Evans,Morgan C. Putnam,Emily L. Warren,Joshua M. Spurgeon,Ryan M. Briggs,Nathan S. Lewis,Harry A. Atwater +9 more
TL;DR: The observed absorption enhancement and collection efficiency enable a cell geometry that not only uses 1/100th the material of traditional wafer-based devices, but also may offer increased photovoltaic efficiency owing to an effective optical concentration of up to 20 times.
Journal ArticleDOI
Enhanced absorption and carrier collection in Si wire arrays for photovoltaic applications (Nature Materials (2010) 9 (239-244))
Journal ArticleDOI
Photoelectrochemical Hydrogen Evolution Using Si Microwire Arrays
Shannon W. Boettcher,Emily L. Warren,Morgan C. Putnam,Elizabeth A. Santori,Daniel B. Turner-Evans,Michael D. Kelzenberg,Michael G. Walter,James R. McKone,Bruce S. Brunschwig,Harry A. Atwater,Nathan S. Lewis +10 more
TL;DR: Arrays of B-doped p-Si microwires, diffusion-doping with P to form a radial n(+) emitter and subsequently coated with a 1.5-nm-thick discontinuous film of evaporated Pt, were used as photocathodes for H(2) evolution from water to yield thermodynamically based energy-conversion efficiencies.
Journal ArticleDOI
Energy-conversion properties of vapor-liquid-solid-grown silicon wire-array photocathodes.
Shannon W. Boettcher,Joshua M. Spurgeon,Morgan C. Putnam,Emily L. Warren,Daniel B. Turner-Evans,Michael D. Kelzenberg,James R. Maiolo,Harry A. Atwater,Nathan S. Lewis +8 more
TL;DR: The inherent performance of these wires thus conceptually allows the development of efficient photovoltaic and photoelectrochemical energy-conversion devices based on a radial junction platform.
