The novel technique consists of attaching cotton wicks immersed in the water (CWIWs) to the backside photovoltaic module. The water is supplied to cotton wicks from top to bottom by gravity which the scientists said helps the effective absorption of cotton and reduces water consumption.

Research from renowned PV scientist Martin Green and colleagues at UNSW reveals that perovskite solar cells may struggle to deal with reverse-bias caused by uneven shading or other issues likely to appear in the field. Both the reverse-bias itself and resulting build up of heat can cause several of the materials commonly used in perovskite solar cells to degrade, and these issues have received only limited attention in research published to date. Solutions, however, are at hand.

New research from the University of New South Wales (UNSW) predicts cumulative polysilicon demand of 46-87 Mt will be required to achieve 63.4 TW of PV installed by 2050.

The 2022 pv magazine Roundtables Europe focused on decarbonization throughout the continent. Linking sustainability to financial performance is a big part of this goal, as the second session, “Sustainability in action, raising the corporate bar,” attested to. During the panel discussion, four experts discussed end of life, circularity, material supply, project development, and the social community, as we approach terawatt solar scale.

In other news, German energy company Uniper said it will test a new salt cavern built for hydrogen storage, while Serbia and Hungary signed a memorandum of understanding to collaborate on renewable hydrogen.

No two projects are alike, and sharing the lessons learned from working on these highly complex systems can help accelerate the deployment of energy storage with essential clean energy assets.

While curtailing solar and wind energy production can be viewed as a lost opportunity, NREL argues that it may be an important feature in the future energy grid dominated by low-cost renewable energy.

Despite polysilicon shortage-induced high module prices, the market saw strong demand in the usually slower summer season this year, due to the global race to net-zero emissions. Corrine Lin, chief analyst at PV InfoLink, expects demand to reach 240 GW, with China and Europe set to contribute more than 80 GW and 50 GW, respectively. Together with the United States, which has paused the introduction of new solar tariffs, the three largest markets will dominate nearly 70% of global demand.

An international research team has developed a new methodology to increase levels of pollination at ground-mounted solar plants. It involves the development of new vegetated land cover below and around solar parks.

Scientists in Belgium have developed a way to assess elevated agrivoltaic projects, by calculating key performance indicators such as energy yield and levelized cost of energy (LCOE). They have found that shade-tolerant crops such as potatoes could potentially be paired with around 1,290 GW of PV capacity in Europe.
