Silicon nanowire solar cells
Loucas Tsakalakos,Joleyn Balch,Jody Fronheiser,Bastiaan Arie Korevaar,Oleg Sulima,James A. Rand +5 more
TL;DR: In this paper, the optical reflectance of the silicon nanowire solar cells is reduced by one to two orders of magnitude compared to planar cells, and a promising current density of ∼1.6mA∕cm2 for 1.8cm2 cells was obtained, with a broad external quantum efficiency of ∼12% at 690nm.
Journal ArticleDOI
Strong broadband optical absorption in silicon nanowire films
Loucas Tsakalakos,Joleyn Balch,Jody Fronheiser,Min-Yi Shih,Stephen F. LeBoeuf,Matthew Pietrzykowski,Peter J. Codella,Bas A. Korevaar,Oleg Sulima,James A. Rand,Anilkumar Davuluru,Umakant D. Rapol +11 more
TL;DR: The broadband optical absorption properties of silicon nanowire (SiNW) films fabricated on glass substrates by wet etching and chemical vapor deposition (CVD) have been measured and found to be higher than solid thin films of equivalent thickness.

High efficiency inorganic nanorod-enhanced photovoltaic devices
Loucas Tsakalakos,Ji Ung Lee,Charles Steven Korman,Steven Francis Leboeuf,Abasifreke Ebong,Robert John Wojnarowski,Alok Mani Srivastava,Oleg Sulima +7 more
TL;DR: In this paper, the authors proposed photovoltaic devices comprising nanostructured materials, which are either 1-dimensional or branched structures, where such structures are used to enhance the efficiency of the photovelectric device, particularly for solar cell applications.
Journal ArticleDOI
Theoretical analysis of effects of deep level, back contact, and absorber thickness on capacitance–voltage profiling of CdTe thin-film solar cells
Jian V. Li,Adam Fraser Halverson,Oleg Sulima,Shubhra Bansal,James M. Burst,Teresa M. Barnes,Timothy A. Gessert,Dean H. Levi +7 more
TL;DR: In this article, the authors show that a U-shape may arise from deep levels, a non-ohmic back-contact, and a thin absorber, which are commonly present in practical CdTe thin-film solar cells.
