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 …

A key strategy for further reducing the cost of solar electricity is through the development and
production of very-high efficiency silicon solar cells (> 25%). The challenge in achieving this …

We present a comprehensive summary of our observations of metal‐rich particles in
multicrystalline silicon (mc‐Si) solar cell materials from multiple vendors, including …

Injection-dependent minority carrier lifetime measurements are a valuable characterisation
method for semiconductor materials, particularly those for photovoltaic applications. For a …

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 …

Single-crystal Czochralski silicon used for photovoltaics is typically supersaturated with
interstitial oxygen at temperatures just below the melting point. Oxide precipitates therefore …

Predominant dislocation types in solar silicon are dissociated into 30°-and 90°-partials with
reconstructed cores. Besides shallow 1D-band localized in their strain field and a quasi-2D …

We have investigated the gettering of transition metals in multicrystalline silicon wafers
during a phosphorus emitter diffusion for solar cell processing. The results show that mainly …

The carrier recombination activity and structural properties of small-angle (SA) grain
boundaries (GBs) in multicrystalline Si (mc-Si) were systematically investigated by electron …

Crystalline silicon solar cells are always moving towards' high efficiency and low cost', which
requires continuously improving the quality of crystalline silicon materials. Nevertheless …
