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 …

In this study, infrared thermography (IR) was used to map the surface temperature
distribution of solar cells while in the reverse bias mode. It was observed that some cells …

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

Grain boundaries (GBs) participate in the photovoltaic energy conversion process in
polycrystalline solar cells as efficient photocurrent collectors and transporters, as shown by …

The rapid growth of the global photovoltaics (PV) industry is increasingly limited by the
availability of suitable Si feedstock material. Therefore, it is very important to explore new …

Synchrotron-based microprobe techniques were used to obtain systematic information about
the size distribution, spatial distribution, shape, electrical activity, chemical states, and …

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 objective of this article is to review, in relation to photovoltaic applications, the current
status of crystalline silicon ribbon technologies as an alternative to technologies based on …

Ultimately, alternative ways of silicon purification for photovoltaic applications are developed
and applied. There is an ongoing debate about what are the acceptable contamination …

The spatially resolved evaluation of power losses in solar cells is a key issue in identifying
technological and material quality problems and realistically judging their influence on solar …
