Laser drilling e.g. of silicon wafers with the StarDisc, produces virtually no micro cracks or edge melting which might weaken the cell during further processing. Rear side contacted solar cells enlarge the solar-active surface and in this way cell efficiency. Current

OSA | Terahertz time-domain spectroscopy of zone …

We investigate the dielectric properties of the 4H and 6H polytypes of silicon carbide in the 0.1-19 THz range, below the fundamental transverse-optical phonons. Folding of the Brillouin zone due to the specific superlattice structure of the two polytypes leads to activation of acoustic phonon modes. We use a coination of ultrabroadband terahertz time-domain spectroscopy and simulations
