Modules & Upstream Manufacturing

The solar industry typically sees itself as being supportive of the environment, humanity, and human rights. Even large Chinese PV manufacturers publish statements to this effect, particularly if they are listed on Western stock exchanges. But what do human rights have to do with the solar industry? What connections exist, asks Martin Schachinger of pvXchange, and how are they important to the future success of the European PV market?

Russian scientists have developed a holographic film based on prismatic concentrators that reduces the operating temperature of solar panels, including thermal-photovoltaic devices. They claim the patented, low-cost technique can even improve PV module efficiency in cloudy weather.

Canadian Solar is pivoting towards energy storage and is preparing to IPO its manufacturing and Chinese solar project activity in China, under the CSI Solar operation, by July.

“Unprecedented” was a term widely used in 2020, as the world grappled with the Covid-19 pandemic. The same word can be similarly applied to the plans and investments in production capacity announced by Chinese PV manufacturers right across the supply chain. But what shape are these expansions taking and what is driving this renewed confidence? Vincent Shaw reports from Shanghai.

Enhanced module appearance and power output can be achieved by a smart cell interconnection technique Longi is employing in its Hi-MO5 module series. But as with all new technologies, there are potential pitfalls.

The latest product in the Vertex series from the Chinese manufacturer has a power conversion efficiency of 21.6%.

The new panel is manufactured with M6 wafers. It features a power conversion efficiency of 20.1% and a temperature coefficient of -0.347% per degree Celsius.

A British-Egyptian research group has tested the use of hydrogels beads for PV module cooling. The micro-sized particles were saturated with aluminium oxide (Al2O3) water-based nanofluids and placed below the simulated PV panels. The experiment showed, according to the scientists, that the hydrogels beads were able to significantly reduce the temperature by between 17.9 and 16.3 degrees Celsius.

Not all rooftops can bear the weight of glass PV modules. Some others have curves and shapes ill-suited to uniform, bulky panels. Flexible modules have long been advanced as the solution here, however the keys to unlocking this potential have proven elusive.

Chris Bowen, who was appointed Labor’s Minister for Climate Change and Energy after a reshuffle in January, told pv magazine Australia he’s keen to make job creation his core focus, framing renewable investment as a Covid recovery solution rather than the end of Australia’s historic coal mining industry, which has dominated Federal narrative.
