Abstract: In the present invention a new solar photovoltaic module is proposed comprising a solar cell comprising a silicon layer having a first surface and a second surface opposite to said first surface. The solar cell further comprises a passivating layer stack comprising a heterogeneous layer arranged on said first surface and/or on said second surface. The heterogeneous layer, having a back surface and a front surface, comprises a non-conducting matrix having a refractive index being lower than 3.0. The heterogeneous layer further comprises inclusions of at least one conductive material in said matrix, and at least some of said inclusions extend from said back surface to said front surface of the heterogeneous layer for electrically connecting the surfaces of the heterogeneous layer.

Abstract: A device and a method for informing passengers of an elevator installation in a building includes at least one information display at at least one start floor and/or at least one second information display in at least one car. The first information display indicates the arrival time of a car at a start or destination floor and the second information display indicates the arrival time of the car at a destination floor.

Abstract: An elevator installation control method with zoning provides changes between zones at an interchange floor. Transportation to or from the interchange floor is by at least one feeder-elevator group and at least one connecting-elevator group. The feeder-elevator group has several feeder elevators that travel in a first zone below the interchange floor and the connecting-elevator group has several connecting elevators that travel in a second zone above it. Trip destinations are entered via destination-call input and the feeder-elevator group and the connecting-elevator group are combined into a multigroup that is controlled by a multigroup control. To optimize the elevator installation operation and utilization, the multigroup control allocates a feeder elevator depending on the number of trip destinations in the first zone to be traveled to by this feeder elevator and/or on the number of trip destinations in the second zone.

Abstract: A method of controlling an elevator installation having a plurality of cars in a building with floors subdivided into several zones wherein travel orders are allocated to the cars. There is no allocation to an elevator car, which has just been allocated a travel order out of or into one of the zones, of any travel order out of or into another of the zones. In the case of a call after a new travel order the number of free elevator cars is compared with the number of still unallocated or still unserved zones and the allocation of the new call and is carried out in dependence on the comparison result.
