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: 11248795Abstract: A finely distributed combustion system for a gas turbine engine is provided. A combustor body may extend along a longitudinal axis. A premixer space may be formed within the combustor body to premix air and fuel. The premixer space is in communication with an array of finely distributed perforations arranged in a wall of the combustor body to eject an array of premixed main flamelets throughout a contour of the combustor body between the upstream base of the combustor body and the downstream base of the combustor body. The array of finely distributed perforations—potentially comprising thousands or even hundreds of thousands of perforations spatially distributed on a miniaturized scale—for ejecting the premixed main flamelets is technically advantageous compared to conventional distributed combustion systems, where injection of relatively longer main flames occurs just at a few discrete axial locations.Type: GrantFiled: March 9, 2018Date of Patent: February 15, 2022Assignee: Siemens Energy Global GmbH & Co KGInventors: Andrew J.
