Manufacturing

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.

The 3 kW inverter has an efficiency of 95% and features a surge power of 9000 VA. According to the manufacturer, the device is compatible with mainstream lead-acid and lithium-ion batteries.

A German research team has developed a photovoltaic-electrochemical device for alkaline water electrolysis that can be linked to battery storage. The proposed system configuration can not only smoothen out the PV power fluctuations and facilitate power coupling, but also improve solar to hydrogen efficiency.

Developed by the Korea Institute of Energy Research (KIER), the “non-destructive” technology is claimed to enable the recovery of 100% of a module’s glass and to allow the reuse of silicon for producing new solar cells with an efficiency of 20.05%.

Solar product detentions at U.S. ports of entry all stem from a June 24 “Withhold Release Order” issued by Customs and Border Protection.
