Patent number: 11588071Abstract: The present disclosure provides a method for rapidly treating a heterojunction solar cell fabricated using a crystalline silicon wafer doped exclusively with n-type dopants to improve surface passivation and carrier transport properties using the following steps: providing a heterojunction solar cell; the solar cell having an n-type silicon substrate exclusively doped with n-type dopants with a concentration higher than 1×1014 cm?3 and a plurality of metallic contacts; illuminating a surface portion of the solar cell for a period of less than 5 minutes and at a temperature between 200° C. and 300° C. with light having an intensity of at least 2 kW/m2 and a wavelength such that the light is absorbed by the surface portion and generates electron-hole pairs in the solar cell. The step of illuminating a surface portion of the solar cell is such that less than 0.5 kWh/m2 of energy is transferred to the surface portion and a temperature of the surface portion increases at a rate of at least 10° C.Type: GrantFiled: October 24, 2019Date of Patent: February 21, 2023Assignee: NewSouth Innovations Pty LimitedInventors: Brett Hallam, Matthew Wright, Moonyong Kim, Daniel Chen

Patent number: 9718355Abstract: A vehicle having a four-wheel-drive system including an auxiliary portion that has an auxiliary driveshaft and drive means between the auxiliary driveshaft arranged to releasably connect a second group of wheels to the driveline via a releasable torque transmitting device. The releasable torque transmitting device is operable to allow slippage of the input portion with respect to the output portions, thereby to vary an amount of torque that is transmitted to the second group of wheels.Type: GrantFiled: October 13, 2015Date of Patent: August 1, 2017Assignee: Jaguar Land Rover LimitedInventors: Russell Osborn, Ian Beverley, Brett Hallam, Mark Rathbone, Steve Mullane, Shaun Wick
