Do solar cells and modules have low light performance?
In this paper the low light performance of solar cells and modules is investigated with a simple approach. Only three parameters (1) the series resistance, (2) the shunt resistance and (3) the ideality factor are used similar as it was already shown by Grunow et al. in 2004.
Why do solar cells have weak-light performance?
In the high wind regime, however, the power production saturates, since these turbines have a reduced nominal power P. This justifies the ansatz Weak-light performance of solar cells depends on the material used .
How can cells with poor weak light performance be identified?
In this way cells with poor weak light performance may be identified in a simple and fast way. Simulated and measured efficiency data for 2BB and 3BB modules, normalized to 100% at 1000 W/m 2 : the difference in series resistance is affecting the weak light efficiency (from ).
Does series resistance limit low-light performance of thin-film solar cells?
The minor role of the R s is in line with findings for silicon solar cells which report that the series resistance only limits the low-light performance if limitations due to the parallel resistance are negligible (Litzenburger et al., 2014). ... Which Parameters Determine the Low-Light Behaviour of CIGSSe-Based Thin-Film Solar Cells? ...
What is the E ciency of a solar cell under indoor lighting?
For R s dropping from tens of kΩ.cm 2 to a few kΩ.cm 2 , the e ciency of a solar cell under indoor lighting can drop from over 20% to less than 5% , . Even for the commercial cells with R sh of 10 kΩ.cm 2 , the e ciency still decreases to be lower than 15% under lowintensity lighting. ...
Does shunt resistivity affect solar cell performance?
... In principle, the shunt resistivity (R sh , unit of kΩ.cm 2 ) has negligible effect on the solar cell performance in the outdoor light, but it becomes catastrophic in low light. For R s dropping from tens of kΩ.cm 2 to a few kΩ.cm 2 , the e ciency of a solar cell under indoor lighting can drop from over 20% to less than 5% , .
