Some times I see the relative thermal coefficient of solar cells Isc (called "alpha" or α) written as
1/K, other times as
I think that
%/K can be seen as
0.01/K, but I am not sure.
Is it correct that
0.000555 1/K = 0.0555 %/K?
PS: absolute Isc,stc of the solar cell = 149.6 mA and I would like to output temperature compensated irradiance with formula:
G = (Isc,meas ÷ (1 + αIsc (Tcell-Tref))) × (Gref ÷ Isc,ref)
thus G = (Isc,meas ÷ (1 + αIsc (Tcell-25))) × (1000 ÷ 149.6)
I think that αIsc needs to be filled out here as
%/K divided by 100) and not as
%/K, otherwise the temperature correction seems too high.
