Disorder-induced localization in crystalline phase-change materials
Theo Siegrist,Peter Jost,Hanno Volker,Michael Woda,P. Merkelbach,C. Schlockermann,Matthias Wuttig +6 more
TL;DR: A metal-insulator transition on increasing annealing temperature for a group of crystalline phase-change materials, where the metal- insulator transition is due to strong disorder usually associated only with amorphous solids, might enable multilevel resistance states in upcoming storage devices.

Thin-Film Silicon Solar Cells
TL;DR: In this article, the current use and challenges of thin-film silicon solar cells, including conductivities and doping, the properties of microcrystalline silicon (the role of the internal electric field, shunts, series resistance problems, light trapping), tandem and multijunction solar cells (a-Si:H/a -Si: H tandems, triple-junction amorphous cells, micro-crystaline-amorphous or “micromorph” Tandems), module production (deposition of thinfilm layers, substrate materials,

Advances in Amorphous Semiconductors
Jai Singh,Koichi Shimakawa +1 more
TL;DR: In this article, the authors present the current level of understanding of the structural, electronic and optical properties of amorphous semiconductors, as well as some of the basic problems associated with the validity of the effective mass approximation and whether K is a good quantum number.

Multi-excitation entropy: its role in thermodynamics and kinetics
TL;DR: Results are presented which support the MEE model as an explanation of MNR and verified predictions of reasonable values of attempt frequencies and cross sections in kinetic processes, which initially appear unreasonable.

Outdoor performance of amorphous silicon and polycrystalline silicon PV modules
Kholid Akhmad,Akio Kitamura,Fumio Yamamoto,Hiroaki Okamoto,Hideyuki Takakura,Yoshihiro Hamakawa +5 more
TL;DR: In this paper, the daily watt-hour efficiency and daily integrated output power (P Wh ) of the a-Si and poly-Si modules have been used to examine the performances of both modules on the basis of two years' data accumulated at outdoor conditions.
