WebApr 11, 2024 · The coronavirus pandemic has drastically impacted many groups that have been socially and economically marginalized such as Hispanics/Latinos in the United States (U.S.). Our aim was to understand how bonding social capital, bridging social capital, and trust played a role in Hispanics/Latinos over the course of the COVID-19 outbreak, as … WebJan 1, 2012 · In this paper, a comparative analysis of three methods to determine the four solar cells parameters (the saturation current (Is), the series resistance (Rs), the ideality factor (n), and the shunt conductance (Gsh)) of the single diode lumped model from its dark curve is presented. These methods are based on Gromov, Werner, and Mikhelashviliet ...

WebMost LEDs are rated for reverse leakage current at 10uA. Some are rated at 100uA. They are all rated at -5V as the absolute maximum rated voltage. From reading thousands of LED data sheets, I have never seen any LED spec'd less than 1uA max although this doesn't mean they all perform this way. I did a spot check at Digikey WebApr 20, 2024 · For those of you who may not know, the dark current saturation (iSat) is often extremely small, somewhere between 1e-15 and 1e-5. The toolbox seems to not work very well with such small numbers, it gives me numbers all over the place and often when I push the fit around by changing the restrictions on the variables it improves drastically.
