Cell cracks have been identified as a major cause of defects in PV modules,
but their effect on performance is less well understood. Researchers Claudia Buerhop-Lutz, Thilo
Winkler, Jens Hauch, Christian Camus and Christoph J. Brabec describe the results of ongoing
investigations into how the electrical power of PV modules is impacted by cracking

The solar industry endured an eventful 2018 with the US establishing its trade tariffs on module imports and China hitting the brakes on deployment, yet, through sheer determination, everyone ended the year feeling fairly optimistic. There is lots of cause for hope in 2019. Module prices are down for the timebeing, seeding subsidy-free markets. We are on the cusp of technological gains that can tilt that balance even further in solar’s favour. Traction with energy storage is clearing up grid headaches and creating new sources of revenue. Our ultimate 2019 briefing addresses all this and more. Our regular Storage and Smart Power section, meanwhile, includes an in-depth look at California’s vibrant market as decrees turn into deployment.

Identifying reliable module supply has become a huge challenge in the PV industry over the past couple of years. Moving forward, the industry needs to create a more globallydiversified manufacturing footprint, thereby avoiding any unexpected trade-related barriers that could be enforced. Understanding which module suppliers are going to prevail in this landscape will become of key importance over the next 12-18 months, Finlay Colville explains.
