Keep your solar cells dry
Scientists in Norway used various imaging and characterization techniques to analyze the cells and other components of silicon PV modules that had been installed in the field for more than 10 years. The group’s aim was to isolate the role of moisture in various mechanisms that cause performance loss over time, and to understand how these mechanisms progress over long-term installation in real outdoor conditions.
Chinese PV Industry Brief: January-May solar installations hit 61.21 GW

The Hydrogen Stream: Hydrogen market to surpass LNG by 2030, says Deloitte
Deloitte says it expects steady hydrogen market growth, with annual revenue projected to hit $1.4 trillion by 2050, while Denmark and the Netherlands have started discussing hydrogen collaboration with the governments of Namibia, South Africa, and Morocco.
IEA-PVPS releases global benchmark for solar irradiance data
IEA-PVPS has published a report to help the solar industry to choose appropriate surface radiation models and data providers based on location and application requirements.
Greece launches 1 GW storage tender
Greece’s energy regulator has announced three separate auctions for standalone energy storage systems connected to electricity transmission networks. The application process for the first auction, which involves 400 MW of energy storage, will be open until July 10.
Rooftop PV system design to improve yield under partial shading
Scientists in India have proposed a new concept that improves the yield of rooftop PV systems under partial shading. This concept combines conventional total cross-tied (TCT) techniques with partial power processing converters (PPPCs), using a resonant switched capacitor converter (RSC) and a switch inductor converter (SLC).
Triple cation perovskite PV cell with ETL based on tin(IV) oxide hits 17.1% efficiency
Qatari researchers have incorporated an electron transport layer (ETL) made of tin(IV) oxide into a perovskite solar cell through air-thermal-annealing, resulting in better efficiency and stability. The device demonstrated an open-circuit voltage of 1.045 V, a short-circuit current of 22.01 mA/cm2, and a fill factor of 74.3%.
What might UK solar expect from a change in government?
Chris Sparkes, lead technician at UK solar installer Solar Fast tells pv magazine simply throwing money at the PV industry will not suffice.
EU raises renewables target to 45% by 2030
The European Union’s new renewable energy directive says that around 100 GW of wind power and PV should be built on the continent every year.
India’s SJVN tenders 1.5 GW of renewables with storage
