Publication number: 20220052639Abstract: A photovoltaic device having a perovskite PV cell having reduced aging. The internal temperature of the perovskite PV cell, or a measure thereof, is determined using a measurement of an electrical parameter. In the case that it is detected that the corresponding measured value exceeds a threshold value, i.e., that the internal temperature is too high, the operating conditions of the perovskite PV cell are adjusted to the effect that the internal temperature reduces again. This can be achieved, for example, by an input resistance of power electronics of the perovskite PV cell being adjusted such that lower ohmic losses occur, as a result of the correspondingly altered electric currents.Type: ApplicationFiled: September 12, 2019Publication date: February 17, 2022Applicant: Siemens Energy Global GmbH & Co.

Patent number: 7992426Abstract: A FET gas sensor having a relatively low operating temperature, for example, room temperature, is free from cross sensitivities from interfering gases by a preceding in-line filter. The sensor's service life is substantially stabilizable by using fabric-like activated charcoal filters which can be regenerated by a moderate temperature increase, and by limiting the diffusion of the analyte gas, which is made possible by the relatively small amount of gas detectable on the sensitive layer of the sensor. This substantially increases the service life of the filters. The gas sensor eliminates cross sensitivities to thereby increase the detection reliability thereof. Also, the gas sensor has relative long term stability and is economical to build. The gas sensor can read relatively weak signals generated by gas-sensitive layers, for example, without other stronger gas signals interfering with the weak signals.Type: GrantFiled: April 21, 2005Date of Patent: August 9, 2011Assignee: Micronas GmbHInventors: Maximilian Fleischer, Uwe Lampe, Hans Meixner, Roland Pohle, Ralf Schneider, Elfriede Simon

Patent number: 7946153Abstract: A gas sensor based on a field effect transistor (“FET”) evaluates both a change in work function of a gas-sensitive layer of the FET and a change in the capacitance of the layer. Thus, two physically independent signals are read from the gas-sensitive layer, each signal representing a sensitivity to a different gas. This reduces the effect of cross-sensitivities; that is, of one gas on the target gas. The underlying physical mechanisms, the first causing a change in the work function in a reaction with gases and the second causing a change in the capacitance of the sensitive layer, are widely different. Because of this, the two parameters demonstrate different gas sensitivities. If the reactions to both gases are known, the effect of the interfering gas on the sensor signal can be compensated for, and with this the concentration of the target gas can be determined.Type: GrantFiled: April 22, 2005Date of Patent: May 24, 2011Assignee: Micronas GmbHInventors: Maximilian Fleischer, Uwe Lampe, Hans Meixner, Roland Pohle, Elfriede Simon

Patent number: 7851202Abstract: A biosensor for detecting an antigen using an antigen/antibody coupling includes: a silicon substrate, at least one interdigital electrode pair structure that is located on the silicon substrate, the electrode pair being interspaced at a maximum distance of 1.0 ?m; a counter-electrode on the silicon substrate; a reference electrode; a first layer of protein, covering at least the interdigital electrode structure; a selective second protein layer applied to the first layer and containing a capture antibody selected specifically with respect to the antigen of interest and to which the antigen can be coupled. A sensor signal can be read on the interdigital electrode structure, if the antigen is coupled to the capture antibody by way of a sample to be analyzed that comes into contact with the biosensor and a redox reactive molecule is enzymatically released on the sensor surface by an enzyme-marked detection antibody likewise coupled to the antigen.Type: GrantFiled: January 27, 2005Date of Patent: December 14, 2010Assignee: Siemens AktiengesellschaftInventors: Maximilian Fleischer, Corinna Haindl, Hans Meixner, Elfriede Simon
