The latest government installation figures reveal a slower start to the year for the United Kingdom, with small-scale installations accounting for the majority of additions. As the UK General Election approaches, there are calls from industry for the next government to act quickly on the issues hindering capacity expansion.

Researchers from Japan’s Riken Center for Emergent Matter Science have fabricated an organic solar cell that has achieved waterproofness without reducing flexibility. At 3 micrometers thick, it is thought to be the first cell of its kind to survive a washing machine cycle and retain efficiency after multiple cycles.

The draft parameters for this year’s capacity market auction in Poland could make the rollout of battery energy storage systems (BESS) much more difficult. The document proposes a significant reduction to the BESS derating factor that could be particularly harmful for longer duration storage systems.

JinkoSolar says it has achieved a 33.24% efficiency rating for its perovskite-silicon tandem solar cells, confirmed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences (CAS).

This week, Women in Solar Europe (WiSEu) gives voice to María Santa María, Head of Projects at BayWa r.e. Iberia. She says that diversity and Inclusion are worth the central stage in a company’s hiring practices and board representation. She also claims that organizations and industry stakeholders have lots to gain by explicitly and outspokenly prioritizing equity and inclusion to create a more inclusive environment for women and other underrepresented groups.

Chinese wafer manufacturer TCL Zhonghuan says it wants to invest around $197.5 million to increase its stake in Maxeon from 22.39% to at least 50.1%. A Maxeon spokesperson told pv magazine that the plan would place the company in a solid financial position.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that a strong polar jet stream and a record-breaking heat dome in May resulted in a stark contrast in irradiance patterns across North America. The western and central USA, along with Mexico, experienced higher than normal irradiance, while the Gulf and East Coast regions faced lower irradiance.

TBEA has developed new products with nominal power ratings of 75 kW to 110 kW and efficiencies of 98.6%. Their European efficiency rating is 98.4%.

While most long-duration energy storage (LDES) technologies are still early-stage and costly compared to lithium-ion batteries, some have already or are set to achieve lower costs for longer durations, finds BloombergNEF.

FTC Solar has developed a hail stow strategy that positions solar modules to minimize the impact of hail and wind, based on a collaboration with VDE Americas.
