Multicrystalline silicon from ingot casting processes has reached a high market share in photovoltaic industry. One reason for this is the increase of the quality of multicrystalline wafers which leads to higher solar cell efficiency. This progress w

Solar cells made from multicrystalline silicon are the ideal basis for photovoltaic systems. The solar cell efficiencies are still limited by the crystal defects (dislocations, grain boundaries) and their electrical activity. As a fast and efficient

Continuously improving crystallization conditions and solar cell processes have lead to steadily increasing efficiencies of solar cells based on multicrystalline silicon. There is, however, still an efficiency gap between mono- and multicrystalline s

The effective lifetime of charge carriers τ eff in multicrystalline silicon (mc-Si) Baysix® wafers (in our case: Bridgman-type) cut from areas close above the ingot bottom is reduced (τ eff < 1 μs). However, the efficiency of solar cells processe
