Periodic Reporting for period 4 - iTPX (In-cavity thermophotonic cooling)
Berichtszeitraum: 2020-04-01 bis 2021-03-31
The main results from the project corroborate the expectation that present technologies already allow reaching ELC at practical operating conditions. The devices fabricated in iTXP indicated that local cooling in an LED is already achievable in the device prototypes studied in the project. Since these devices still circumvented some of the challenges met in real light emitters and cooling devices, the results suggest that the remaining bottlenecks in developing new optical cooling technologies are more technical than fundamental in nature, and require 'simply' more efficient designs to extract light and to reduce the resistance of the devices. Both of these are deemed to be feasible using the know-how and fabrication capabilities gained in the project.
