University of New South Wales researchers have identified four failure modes caused by damp heat in heterojunction solar panels with a glass-back sheet configuration. The failures could result in power losses ranging from 5% to 50%.
The Renewable Energy Test Center (RETC) raised the issue of ultraviolet-induced degradation of the trending technology in its PV Module Index 2022.
The Indian manufacturer expects to start production from its second factory by June this year, bringing its total solar panel manufacturing capacity to 850 MW.
Meyer Burger is working with several research institutes in Switzerland and Germany to integrate perovskite tandem technology into its manufacturing processes.
Longi has launched a series of modules featuring an all-new hybrid passivated back contact cell technology, with which it claims a maximum module efficiency of 22.8% in mass production. It will initially offer the modules in 54, 60, 66 and 72 cell formats, targeting rooftop and distributed generation applications.
Clean Energy Associates said in a new report that it expects polysilicon production capacity to exceed PV installations next year.
China’s Trina Solar has shipped more than 8 GW of solar modules to India. It is looking to strengthen its foothold in the market with the launch of n-type PV modules.
As the PV industry scales to annual terawatt-level production to rapidly curtail the world’s emissions, it will become more challenging to continue the cost reduction trajectory. Increasing module production from current levels of 200 GW to 300 GW to several terawatts each year will consume significantly more material resources than the industry currently uses. This will require consideration of the additional materials to be sourced, writes Alison Lennon, chief scientist at Sundrive Solar and professor at the UNSW’s School of Photovoltaic and Renewable Energy Engineering.
India’s Adani Solar will expand its PV cell and module manufacturing capacity to 10 GW per year by 2025, with backward integration up to the polysilicon stage.
Enel Green Power’s new solar panel has average efficiencies ranging from 22.6% to 22.9% and a temperature coefficient of -0.24% per degree Celsius. It is based on an n-type solar cell with G12 format and a power conversion efficiency of 24.6%.
