IoT-controlled jute cooling reduces PV module temperature by 21.4 C
Tunisian researchers have developed an IoT-controlled jute-fabric cooling system that reduced PV module temperature by up to 21.4 C and increased power output by 40.44% in desert conditions. The system uses 86% less water than previous natural-fiber cooling approaches while achieving an 81.3% water recovery rate.
Midsummer, Indonesian firm sign deal for CIGS thin-film solar manufacturing plant
Midsummer’s minority stake in a new Indonesian joint venture marks its second copper indium gallium selenide (CIGS) manufacturing partnership abroad, following a similar equipment-and-know-how deal in Colombia and a decision to shelve its own planned Swedish factory.

AI predicts wind-uplift resistance of solar PV piles
Researchers in Iran have developed an interpretable artificial neural network to predict the uplift capacity of driven steel piles used in utility-scale PV projects. The model achieved a mean absolute percentage error of 7.63%, with pile penetration rate and soil friction angle emerging as the most influential predictors.
France seeks recyclers for CdTe, CIGS solar modules
Soren is seeking companies to develop thin-film PV module recycling solutions in France for CdTe and CIGS technologies, with proposals due Oct. 21, 2026. The selected solution will prioritize a 1,300-tonne batch of CdTe modules as recycling volumes are projected to rise sharply through 2037.

Polysilicon playbook
Now that the United States has finally announced the outcome of its Section 232 investigation into polysilicon imports, industry analysts and investors alike have been weighing up the expected pros and cons of the policy’s likely impacts, particularly on ingot, wafer and cell manufacturing.
Optimized semi-transparent PV greenhouse design increases energy output by 20.1%
An international research team has developed an optimized semi-transparent PV greenhouse design that increases solar electricity generation by strategically allocating PV surfaces to south-facing roofs and walls. Using an improved optimization algorithm, the design increased annual energy output by 20.1% and outperformed conventional greenhouse geometries by up to 56.86%.
Heterojunction’s long road to the US solar factory
For a cell technology that has spent much of the past three decades on the verge of a breakthrough, heterojunction (HJT) is enjoying another moment in the spotlight. This time, however, the setting is somewhat unexpected – rather than the established manufacturing centers of China and Southeast Asia, some of the most significant new commitments to HJT are emerging in the United States, Finlay Colville reports.
