Abstract: A solar panel includes a stack of at least one back contacted solar cell, a first encapsulant layer and a back-sheet contact layer. The solar cell includes back side electrical contacts. The back contact sheet layer includes a patterned conductor circuit, which has contacting areas located at locations corresponding to locations of the electrical contacts on the at least one solar cell. The encapsulant layer has a pattern of openings at locations corresponding to the locations of the electrical contacts. The solar cell is arranged on top of the first encapsulant layer that is positioned on top of the back-sheet contact layer, with the rear surface of the at least one solar cell facing the patterned conductor circuit surface. Each electrical contact is connected through a corresponding opening in the first encapsulant layer with a respective corresponding contact area of the conductor circuit by an interconnecting body.

Abstract: A rotary evaporator (1) having a cooler (6), wherein temperature sensors (15, 17) are disposed in the inlet (14) and outlet (16) of the coolant into or out of the cooler (6), and a volume flow rate of the coolant through the cooler (6) is determined. The initiation or termination of condensation in the cooler (6) is derived from an increase or decrease in the difference of the temperatures (X) at the temperature sensors (15, 17). The volume of the condensed distillate (10) is determined from the difference in temperatures (X), and a distillation volume control is performed. By regulating the heating power of the heater (11) and/or the pressure in the system, the loading of the cooler (6) is controlled as a function of the difference in temperatures (X).

Abstract: Method for dyeing a layer of a nanocrystalline material on a substrate using a liquid dye, comprising the successive steps of (i) providing said layer on a substrate, (ii) providing an apparatus for dyeing said layer, which apparatus comprises at least a supply container for the liquid dye, a closable substrate holder provided with at least one inlet and at least one outlet for a substrate provided with a layer of nanocrystalline material, and conduit and circulation means for causing the liquid dye to circulate through the supply container and the substrate holder, (iii) placing the substrate with said layer in the substrate holder and closing the substrate holder, and providing a liquid dye in the supply container, and (iv) causing the liquid dye from the supply container to circulate for a determined time through the substrate holder, and apparatus for performing this method.

Abstract: An airbag system for a motor vehicle including a gas bag having first and second chambers. The system includes an inflator and a arranged in the connecting portion so that gas is guided into both the first and second chambers. The system includes at least one protective layer extending from the mass flow divider into the first chamber. Upon inflation of the gasbag, an inner pressure in the first chamber is significantly higher than an inner pressure in the second chamber, and wherein the protective layer comprises a flexible material deformed by the inner pressure in the first chamber to prevent gas from flowing from the first chamber through the connecting portion into the second chamber.
