The German institute has achieved another efficiency record for multi-junction solar cells. More cost-effective production methods for III-V-layer cells have also been advanced during work as part of the MehrSi project.

The PV panel testing company has left the fold four years after being acquired by DNV GL. Insiders have stressed the move should not be problematic as PVEL was allowed a degree of independence after it was acquired.

Upon completion, the long-term storage benefits of compressed hydrogen, coupled with an abundance of solar radiation in the summer months, will allow for a fully energy-sufficient 172 home apartment block in Sweden.

Having reflected on the year gone by, it is time to turn attention to the coming year. Many predictions may not fully, or even partially, bear the fruit they promise – and the unexpected is always lurking in the background – however they can be a useful indicator of certain pathways and growth areas. With this in mind, the pv magazine team has compiled a list of the top 14 solar PV and energy storage trends expected to characterize 2019. What do you think? Have we missed anything?

Japan’s JGC Corporation reports an efficient method of converting hydrogen to ammonia, which can later be combusted to generate carbon-free electricity. Ammonia, according to JGC, has various advantages over hydrogen in terms of safety and cost effectiveness.

Despite the rollercoaster of emotions experienced throughout the year, the final quarter of 2018 wrapped up on a relatively positive note, with the scrapping of Spain’s sun tax, and ambitious goals either announced or reaffirmed. Read on to discover what happened in the months of October to December.

The tension between the cost cutting and performance boosting opportunities presented by new technologies and the tendency for risk aversion is never more evident than in PV module materials. This applies nowhere more than in backsheets, where new innovations are big on promise, but must convince manufacturers and the market of their long-term performance.

China continued to take center stage in Q3 2018; however the focus shifted from its now notorious policy change. In both positive and negative news, Europe announced the end of the MIP, at almost the same time as the United States slapped tariffs on Chinese imports of inverters, AC modules and non-lithium batteries. Yin yang. Ping pong.

While China’s PV policy announcement dominated the headlines in Q2 2018, there were a lot of other significant happenings in the world of solar, not least the EU’s 32% renewable energy targets, rumors of U.S. tariffs on inverters, PV records in Germany, and unexpected new partnerships. Read on to discover the highlights from April to June.

Whether caused by improper production processes, poor treatment in transport and installation, climate conditions or any other issue, performance reducing microcracks are a major source of stress for PV developers and project owners. Now, an EU funded research project has found that a different type of stress could provide a solution, and even “heal” some existing cracks.
