Red/blue measurement

Early detection of process instabilities

Things can go wrong, that’s why things do go wrong, even in the best production line. This is when the red/blue measurement helps to find out what went wrong and brings efficiency back to the optimum level!

How it works:

  • Light with a short wavelength (blue light) is easily absorbed by silicon near the front surface

  • Silicon is a weak absorber of light with a long wavelength (red light), which is thereforeabsorbed throughout the whole silicon wafer

The “blue efficiency” and the “red efficiency” depend on different mechanisms:

  • The blue efficiency depends on the front contact with, for instance, the emitter, which is generated by phosphorous in-diffusion

  • The wafer quality and the back contact affect the red efficiency

  • Suitable for single-junction solar cells

This opens the door for the special red/blue measurement developed by WAVELABS!
