We investigated the absorption of carboxyhemoglobin (COHb) using a Fourier transform infrared (FTIR) microscopy system. Weak absorption at 1969 cm-1 due to Fe<--CO and strong absorption due to N-H stretching vibration, > C = O stretching vibration and -NH bending vibration (1544 cm-1) were observed. The ratio of absorbance at 1969 cm-1/1544 cm-1 can be used(More)
Reduced optical transmittance of encapsulants resulting from ultraviolet (UV) degradation has frequently been identified as a cause of decreased PV module performance through the life of service in the field. The present module safety and qualification standards, however, apply short UV doses only capable of examining design robustness or “infant mortality”(More)
