New CIGS solar cell design with antimony trisulfide promises 31.15% efficiency

The novel solar cell uses antimony trisulfide (Sb2S3) as the back surface field (BSF) layer. According to its creators, this layer can be included in conventional CIGS solar cells to improve their efficiency and reduce the absorber material’s cost.


First attempt to build thin-film solar cells relying on absorber made of silver, barium, titanium, selenium

An international research team has demonstrated, for the first time, the technical feasibility of solar cells relying on absorbers made of silver, barium, titanium, and selenium (Ag2BaTiSe4). The simulations showed these devices may reach efficiencies of up to 29.8% and be based on different buffer layer materials.


World Bank seeking advisers to assess feasibility of floating solar in Mexico

The World Bank is accepting expressions of interest to provide consultancy and feasibility study services for floating solar facilities at two hydropower reservoirs operated by Mexico’s National Electricity Commission (CFE).


The Hydrogen Stream: Researchers test marine green hydrogen feasibility

Mexican researchers have revealed test results for offshore wind-based hydrogen production, while Turkey has started negotiating hydrogen facility partnerships with the United Arab Emirates.


Heat pump design to reduce footprint of solar thermal installations

A US-Mexican research team has investigated how linking heat pumps with solar thermal collectors may help reduce the surface needed to deploy the collectors themselves. The scientists found the proposed solution may not only significantly reduce the footprint of solar thermal systems but also provide a lower levelized cost of energy compared to fossil fuels.


CIGS solar cell using aluminum doped zinc oxide film achieves 9.53% efficiency

Scientists have developed a technique for producing AZO and i-ZnO/AZO bilayer structures in solar cells that greatly improves cell efficiency and durability. Using a low power deposition method that avoids raising the substrate temperature, the team achieved a power conversion efficiency of 9.53% with good transmittance.


Maxeon’s PV module capacity hits 2.5 GW in Mexico

Maxeon Solar Technologies says it has invested $70 million to upgrade its panel factory in Mexicali, Mexico, to 1.8 GW. The remaining capacity is provided by a 700 MW facility that the Singapore-based manufacturer operates in Ensenada.


April irradiance up for US and Mexico, down for Canada

In a new weekly update for pv magazine, Solcast, a DNV company, presents the solar irradiance data it collected for North America in April. These data show that positive departures from normal April irradiation benefitted solar producers from California, Baja California and Sonora right across the continent to Pennsylvania, New Jersey and Maine.


Mexico’s Solarever commissions new 500 MW solar panel production line

Mexican PV module manufacturer Solarever expects its newly announced production line has raised the annual capacity of its factory in southwestern Mexico to 1.1 GW.

Hindsight to foresight: Applying lessons from solar to battery storage

Battery storage for clean energy is one of the hottest topics in the energy industry. In some cases, lithium-ion batteries may have shorter expected lifetimes than other energy system elements like solar modules, and safety is incredibly critical for battery fleets. In this pv magazine Webinar, we’ll learn about innovative battery analytics tools and services that simplify ownership, prioritize safety, drive competitive differentiation, and maximize profitability.
