Spanish consortium to simplify hydrogen production through photoelectrocatalysis

Spanish energy giants Repsol and Enagás are planning to build an electrolyser based on photoelectrocatalysis at an industrial complex owned by the oil company in Puertollano in 2024. The device receives direct solar radiation and with a photoactive material it generates the electrical charges that cause the separation of the water molecule into hydrogen and oxygen.

Sunday read: the effects of defects

Mónica LiraCantú leads a research group investigating nanostructured materials for photovoltaic energy at the Catalan Institute of Nanoscience and Nanotechnology (ICN2). Recently, her group led a project that looked deep into the crystalline structure of a perovskite solar cell, revealing new information about the formation of defects in the material and how they could be engineered to improve both efficiency and stability. pv magazine caught up with the Barcelona-based scientist to discuss the state of the art in perovskite solar cells and remaining challenges on the road to commercialisation.

When does revamping pay off?

With projects in many PV markets ageing past the 10-year mark – with major leaps in technology having occurred in that time – revamping is a popular topic among asset owners. Pv magazine spoke with Asier Ukar, general manager of the Spanish subsidiary of German testing company PI Berlin, to uncover the benefits of revamping PV projects with new components and also to examine the challenges and risks involved.

Storing solar power with recycled batteries from Nissan

Spanish renewable energy company Acciona is testing four second-life batteries with a combined capacity of 130 kWh at its 1.2 MW experimental solar park in Tudela, in the Spanish region of Navarra.

Australian financiers invest $141 million in concentrated solar power (CSP) plants in Spain

Australian financial group Macquarie Asset Management on Monday announced a €90 million (AU$141.5 million) debt investment in a portfolio of concentrated solar power (CSP) plants in southern Spain.

New walkways for the installation of rooftop PV systems

Spanish mounting system provider Alusín Solar has developed a solution to enable the transit of installers on roofs. It has recently commissioned a production line for this product, which it dubbed Carex.

Perovskite stability, and the effects of defects

An international team of scientists fabricated perovskite solar cells which retained almost all of their initial 21% efficiency after 1,000 hours under continuous operation at their maximum power point. The researchers credit this performance to their discovery of an additive that served to ‘block’ ions that cause device degradation, and also hope their work will contribute to an improved understanding of the relationship between efficiency and stability in perovskite PV.

Adhesive mounting system for any kind of solar modules

The system, developed by Spanish specialist Alusín Solar, is being tested by Endesa in a 9.8 MW project for self-consumption. The mounting structure is made with aluminium bars that, instead of being fixed to the roof with screws, are attached through a double-sided adhesive.

Hydrogen to be produced from seawater in Spanish solar-plus-storage plant

Spanish PV project developer Gransolar is planning to build a large-scale green hydrogen production plant in the Port of Almería, in southern Spain.

Solar pavement for historic square in Barcelona

The municipal government of Barcelona is supporting the development of a 50-square-meter pilot project to test the feasibility of PV-paving tech.
