Abstract: Methods and systems for reducing solar cell degradation are provided. The methods and systems related to frequently applying large reverse bias current-voltage (J-V) sweeps to the cell to reduce the rates of internal degradation of the solar cells. The frequent sweeps serve to detrap charge carriers formed in the cell due to photo-oxidative damage. This detrapping reduces the rate of power conversion efficiency (PCE) degradation throughout the life of the solar cell.

Abstract: This invention generally relates to commissioning in Zigbee Light Link (ZLL) networks. The proposed solution takes advantage of the existing Touchlink procedure in order to enable a controller device joining a ZLL network without having to Touchlink with every single lighting devices comprised in the ZLL network. This way, the one or more lighting devices of the ZLL network may be directly controlled by the newly joined controller device after a single Touchlink thanks to the introduction of a commissioning device. The commissioning device may be configured to provide specific joining information and binding information to the controller device. Further, a timer in the commissioning device may be triggered to lapse after a given period of time where the controller may be disconnected from the ZLL network.

Abstract: A phase detector includes a counter to generate the integer portion of a number of complete cycles of an output clock at each active edge of a reference clock. A time to digital converter in the phase detector generates the fractional portion of the number of complete cycles of the output clock at each active edge of the reference clock. The sum of the fractional portion and the integer portion is subtracted from an accumulated value obtained by accumulating a pre-determined number to generate an error signal as the output of the phase detector. The counter is read at an active edge of one of two re-timed clocks derived from the reference clock. Each of the two re-timed clocks is generated based on a comparison of the fractional portion with a pair of thresholds. Errors due to metastability in reading the counter are thereby avoided.
