A key efficiency-limiting factor in silicon-based photovoltaic (PV) devices is the quality of the
silicon material itself. With evolving cell architectures that better address other efficiency-loss …

Imaging the band-to-band photoluminescence of silicon wafers is known to provide rapid
and high-resolution images of the carrier lifetime. Here, we show that such …

Polycrystalline silicon (commonly called" polysilicon") is the material of choice for
photovoltaic (PV) applications. Polysilicon is the purest synthetic material on the market …

This study aims to better understand the influence of crystallographic structure and impurity
decoration on the recombination activity at grain boundaries in multicrystalline silicon. A …

In situ and operando measurement techniques combined with nanoscale resolution have
proven invaluable in multiple fields of study. We argue that evaluating device performance …

The effect of iron contamination in multicrystalline silicon ingots for solar cells has been
investigated. Intentionally contaminated p-and n-type multicrystalline silicon ingots were …

Silicon has remained the material of choice for both the microelectronic and photovoltaic
(PV) industries for a few decades. In addition to its abundance, silicon can be refined to an …

In this work, we applied internal quantum efficiency mapping to study the recombination
activity of grain boundaries in High Performance Multicrystalline Silicon under different …

Segregation behavior of transition metal impurities (Fe and Ti) during the Al–Si solvent
refining of silicon was investigated. A directional solidification with induction heating was …

This manuscript concerns the application of infrared birefringence imaging (IBI) to quantify
macroscopic and microscopic internal stresses in multicrystalline silicon (mc-Si) solar cell …
