Latest Patents
Jooss's latest patents include a method and device for passivating defects in semiconductor substrates. This invention focuses on methods and apparatus for passivating defects in semiconductor substrates, especially silicon-based solar cells. The method involves irradiating the substrate with electromagnetic radiation during a first process phase, using wavelengths below 1200 nm and an intensity of at least 8000 Watt/m². This process can lead to substrate heating or controlled temperature management. Following this, the substrate undergoes a temperature-holding phase where it is again irradiated, while the opposite side is cooled via contact with a support device.
Another significant patent is for a solar cell with buried contacts in recesses on its first surface. This design includes a metal layer on a lateral face that extends into a lateral zone of the opposite surface, serving as the first electrode. A second electrode is produced on the second surface, ensuring that the solar cell is equipped with a back connection.
