U.S. researchers are collaborating on the development of optical coatings that could extend the lifetimes of PV cells.
Dutch company Rads Global Business has developed an anti-soiling coating for solar PV modules that is claimed to reduce cleaning cost by around 60%. The anti-reflective and anti-corrosive coating is also said to mitigate potential-induced degradation (PID).
The developer of the material, US-based specialist Pellucere, says its innovation can raise PV energy yield 3.5-4.2%.
A study has estimated the cost of PV project soiling may increase from €3-5 billion last year to €4-7 billion by 2023 due to more extensive deployment in high insolation and soiling-affected regions, such as China and India. The authors of the paper outlined the potential of soiling mitigation technologies while stressing more R&D is needed to reduce costs and for the adoption of such measures on a larger scale.
pv magazine’s Future PV Roundtable, held at the 2018 Renewable Energy India (REI) Expo in Greater Noida, discussed how India can better adopt bifacial solar cell and module technology – the future of power generation. Prominent industry speakers also put forth their views on how standards can catalyze solar innovation for India-specific challenges, and on PV materials and components for enhanced module efficiency and recycling.
The Dutch specialty group believes its sand-resistant coating for solar panels will be particularly suitable for desert areas. The new technology is currently being tested at a solar plant in China’s Gobi Desert.
