Modules & Upstream Manufacturing

An international research team has assessed the impact of soldering flux on heterojunction solar cells and has found that the composition of this component is key to prevent major cracks and significant peeling.

Researchers in China have investigated the effect of the overhead height and tilt angle on thermal and energy-saving performance of photovoltaic roof and have found that the comprehensive energy-saving efficiency of parallel overhead photovoltaic roofs are optimal in summer and the worst in winter.

Huasun Energy says it has signed a 3 GW supply deal with Hongyang New Energy Development Group for heterojunction (HJT) solar panels. The PV modules will be used in Hongyang’s solar-plus-storage hydrogen-ammonia projects in China’s Xinjiang region, with delivery set by the end of 2026.

N-ink, a spinoff of the Linköping University, has developed conductive inks that can be used in the charge extracting layer of organic solar cells and in transport layers of perovskite solar cells.

Trina Solar has filed a lawsuit against Canadian Solar and its subsidiary, seeking $147 million in damages for alleged infringement of tunnel oxide passivated contact (TOPCon) cell patents. The case, accepted by the Jiangsu High Court, underscores the rise of intellectual property disputes in China’s competitive solar sector.

Hard-to-abate segments in the energy transition, such as the chemical industry and marine transportation, require electricity-based e-methanol in large quantities. The transport costs could be a key factor in determining the best locations for future green e-methanol projects.

Developed by a research team including experts from Australian specialist Clearvue, the new PV windows were also able to reduce water usage in a greenhouse by 29%. The group believes that a fully glazed solar greenhouse could offset up to 100% of the energy consumption in worldwide locations by using adaptable and efficient temperature control techniques.

Waaree Energies has started commercial production from the first 1.4 GW of its planned 5.4 GW solar cell manufacturing capacity in Gujarat, India.

An international team has utilized an n-type polymeric additive to stabilize C60 molecules for use in inverted perovskite PV cells. Thanks to this approach, the researchers built a solar cell with the highest efficiency value ever recorded for perovskite devices based on solution processed C60 electron transport layers.

The Canadian building-integrated PV manufacturer has launched semi-transparent and opaque solar PV railing systems for balconies or walkways, for retrofit or new buildings. The products are delivered with support bars, concealed cabling and a choice of mounting systems.
