Modules & Upstream Manufacturing

The airplane is powered by 22 square meters of solar cells with an efficiency of up to 24% and 14 kWh of lithium-ion batteries. According to its creators, it can reach an altitude of 25,000m.

Researchers in China have analysed how the marine environment influences the performance of PV modules deployed on ships, and have found that salt particles can be detrimental to their performance as these act as both heating agents and a factor reducing solar irradiance. The temporary cooling effect provided by seawater is not sufficient to offset the impacts of salt spray and ensure increased power yields.

Australian startup H2X is banking on bringing automotive manufacturing back to Australia with hydrogen. After its Warrego ute was met with startling fanfare last week, pv magazine Australia caught up with the company’s corporate affairs specialist, Tony Blackie.

Called SolFlex, the frameless panel is based on 22%-efficient solar cells and is designed for high, one-sided heat load. The standard product measures 100x100x2.9cm, weighs in at 3.4kg, and has a power output of 170 W.

The European Union’s proposed carbon border tax on imports of energy-intensive goods could push up prices of steel, aluminium and raw materials, which could add costs to the supply chain for solar PV installations. In the longer run, however, the border tax could also offer solar PV manufacturers new opportunities to source materials with a lower carbon footprint.

India’s solar module makers have built a strong track record, and now the country is set to see vast battery facilities developed. Uma Gupta provides a look into ambitious manufacturing projects and the wider enabled ecosystem.

The performance of the solar cell contacts can be improved with laser-assisted current treatment. The process does not damage the solar cells but only optimises faulty semiconductor-metal contacts.

The panel is based on 14.9%-efficient organic PV cells with a surface of 1.1 cm2 that the same research group unveiled in September 2020. The solar cells were interconnected using laser structuring.

The sky is the limit. Fortunately, this expression does not apply to current prices for PV panels, which have recently declined, following a continuous rise since the beginning of the year. Whether this situation holds, or whether prices drop further in the coming months is hard to say at the moment, writes Martin Schachinger of pvXchange. Polysilicon prices and thus wafer and cell prices could be in for a slight decline. However, a decisive movement in module prices in general is unlikely before the fourth quarter.

Lithium-ion batteries remain the front-runner to power EVs, but without clearer recycling plans from the European Union and the United States, the balance isn’t yet tipped away from heavy mining of new materials to focus on supplying industry needs, writes Ian Morse.
