LFC on Screen Printed Aluminium Rear Side Metallization
2009In this paper we report about first results regarding laser fired contacts (LFC) on an optimized screen printed aluminum rear side layer and compare it with our “standard” LFC procedure on evaporated aluminum layers. First of all, the influence of the laser pulse energy, pulse duration and amount of pulses on the resistance of one contact is evaluated.

Comparison of three different metallization concepts for LFC cells
2010Laser fired contacts (LFC) are a well known technique to apply the rear side electrode on dielectrically passivated solar cells. Thereby, the aluminum on top of the passivation is locally heated by means of single laser pulses and subsequently alloyed into the silicon.

Mass flow requirements for LFC wing design
Aircraft Systems and Technology Meeting, 1977The problem of determining optimum suction mass flow requirements for LFC wings is addressed. Some previous methods for predicting the extent of laminar flow over swept wings with suction are briefly reviewed. These range from the purely empirical to those utilizing tabulated linear stability computations. The present method is described.

Single and two area LFC using RBF
2015 International Conference on Recent Developments in Control, Automation and Power Engineering (RDCAPE), 2015The control of operating frequency is of utmost importance in the power system operation and control from stability point of view. Conventionally load frequency control is done by employing PI controllers. Immediate control of system frequency oscillation is very vital to avoid hazardous conditions.

Technical Challenge of Discrete Suction LFC Vehicles
OCEANS '79, 1979The drag and propulsive power of suction LFC undersea vehicles can be reduced by factors of 6 and 8, respectively, with accompanying reduction in self generated noise. This dramatic improvement in performance has not yet been demonstrated on an undersea vehicle, primarily because of two technical problems: (1) the prevention of ocean, particle capture ...
