Scientists in France tested the effectiveness of various encapsulant materials, used to laminate solar cells into modules, at protecting cells and other components from damage caused by ultraviolet (UV) light. Their findings show that encapsulants with additives specifically designed to absorb UV light tend to turn yellow over time, which can contribute to various other problems with performance.

The research group led by Professor Martin Green has published Version 62 of the solar cell efficiency tables. There are 21 new results reported in the new version, a record number for the Tables.

At Intersolar in Munich, pv magazine spoke with Jenny Chase, solar analyst at BloombergNEF, about falling solar module prices, oversupply, bottlenecks in the European markets, and labor issues. According to Chase, lower panel prices won’t instantly create demand, and manufacturers should prepare to deal with very low margins. She also said we can expect to see more consolidation in the industry, and bankruptcies for uncompetitive producers may be unavoidable.

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.

The National Energy Administration (NEA) says China installed 61.21 GW of solar in the first five months of this year, bringing the nation to nearly 453 GW of cumulative installed PV capacity by the end of May.

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%.

Researchers in Saudi Arabia have conducted a series of tests to investigate the temperature coefficient of the short circuit current in perovskite-silicon tandem solar cells and have found that it may not be considered a proper metric to assess these devices’ performance and behavior.

Asier Ukar, the director of PI Berlin Spain, discusses the importance of addressing the risks associated with tunnel oxide passivated contact (TOPCon) tech early on, even though it outperforms (passivated emitter rear contact (PERC) when considering standard and tangible indicators.

Scientists in India carried out a comprehensive study into the impacts of soiling on PV modules – measuring the amount of performance loss caused by different types of dust and bird droppings, and for modules installed at various tilt angles, in the hot-dry climate of Vellore in southern India. Their findings could allow developers to better take into account and mitigate the effects of soiling during site selection and system design.

Nithin Sai has revealed plans to begin making PV panels with a new Mondragon Assembly production line. The initial manufacturing capacity is set at 500 MW for M10, half-cut cells, with plans for a second-phase expansion to reach 2 GW.
