Hello, I'm having some trouble with simulatin thin-film systens in PVsyst 5.65. I got the pv data from photon, for the DuPont Apollo DA142-C (that is amorpohus/Microcrystalline Silicon) but the temperature power coefficient is always positive. The problem is that my system is operating better, i.e., it is gerenating more power with a higher temperature. I found that there's a 'hidden' coefficient for amorphous, the d²MuTau, but it's always shown as "0.0 /V" in the module. Has anyone faced this problem before? Or give me a tip about solvin this issue? Thanks in advance.
