User impersonation/delegation in a token-based authentication system
A “trusted service” establishes a trust relationship with an identity provider and interacts with the identity provider over a trusted connection. The trusted service acquires a token from the identity provider for a given user (or set of users) without having to present the user's credentials.

Method for forming metal silicide layers
The present invention is related to a method for forming a metal silicide layer on a textured silicon substrate surface. The method includes providing a metal layer on a textured silicon substrate and performing a pulsed laser annealing step providing at least one UV laser pulse with a laser fluence in the range between 0.1 J/cm2 and 1.5 J/cm2 and with a laser pulse duration in the range between 1 ns and 10 ms.

System and method for tin plating metal electrodes
Systems and methods for fabricating a photovoltaic structure are provided. During fabrication, a patterned mask is formed on a first surface of a multilayer body of the photovoltaic structure, with openings of the mask corresponding to grid line locations of a first grid. Subsequently, a core layer of the first grid is deposited in the openings of the patterned mask, and a protective layer is deposited on an exposed surface of the core layer. The patterned mask is then removed to expose the sidewalls of the core layer. Heat is applied to the protective layer such that the protective layer reflows to cover both the exposed surface and sidewalls of the core layer.
Photoelectric conversion device and manufacturing method thereof
A stack including a first electrode, a first impurity semiconductor layer having one conductivity type, an intrinsic semiconductor layer, a second impurity semiconductor layer having an opposite conductivity type to the one conductivity type, and a light-transmitting second electrode is formed over an insulator. The light-transmitting second electrode and the second impurity semiconductor layer have one or more openings. The shortest distance between one portion of the wall of one opening and an opposite portion of the wall of the same opening at the level of the interface between the second impurity semiconductor layer and the intrinsic semiconductor layer is made smaller than the diffusion length of holes in the intrinsic semiconductor layer. Thus, recombination is suppressed, so that more photocarriers are generated due to the openings and taken out as current, whereby conversion efficiency is increased.
