As p-type mono cell efficiencies edge closer to their limits, n-type cells are increasingly being recognized as next-generation technologies, writes PV InfoLink analyst Amy Fang. Manufacturers have focused their research and development efforts in recent years on the creation of commercially viable pathways for heterojunction (HJT) and tunnel-oxidized passivated contact (TOPCon) cells.

According to a new report from the International Energy Agency (IEA), health risks from lead in crystalline silicon PV panels are one order of magnitude — or about one-tenth — below the risk levels set by the U.S. Environmental Protection Agency.

Plus, Australia’s Greens want renewables front and center of the post Covid-19 economy and Mexican plant owners are overturning a politically-motivated ban on clean energy, however, Indian developer Acme solar says pandemic delays warrant it reneging on the terms of the record-low solar price agreement it signed.

Australia has certainly demonstrated its appetite for solar power. Now, with the average lifespan of a solar panel being approximately 20 years, many installations from the early 2000’s are set to reach end-of-life. Will they end up in landfill or be recycled? The cost of recycling is higher than landfill, and the value of recovered materials is smaller than the original, so there’s limited interest in recycling. But given the presence of heavy metals, such as lead and tin, if waste is managed poorly, we’re on track for another recycling crisis. A potential time bomb could present itself as an opportunity, however, if the global EV industry showed an interest in the recovered solar products.

For an investor of large-scale solar PV power plants, efficiency and reliability are two of the most interesting issues. For rating purposes, the Performance Ratio (PR) factor, has been created. However, this metric is only suitable for comparisons to a limited extent, argues Edwin Cunow, owner of LSPV Consulting.

Cell supply shortages could kick-start manufacturing activity in India, EV car sales are braced for a fall while still gaining market share and a new date has been set for the world’s biggest solar trade show.

The solar learning curve usually applied to panel costs has been extrapolated to the larger, non-module element of the price of solar electricity generated by big projects, leading one commentator to predict new solar projects could be cheaper than legacy fossil fuel plants within 10-15 years in certain markets.

EV sales are set to be 1.7 million off because of the economic fallout of the Covid-19 crisis, however analyst BloombergNEF predicts that will be less of a hit than the anticipated fall in sales of conventional cars, increasing the penetration of electric models into the overall market.

Portugal set a new coal-free record because of the pandemic as Belgium and Israel moved to help the renewables industry. But there was grim news in Mexico and Turkey, and Bangladeshi clean energy firms have appealed for more assistance.

Measuring the performance of a solar cell is a tricky affair, and even more so for new technologies such as perovskites and tandem cells. In the laboratory, these are measured over a period of several minutes to ensure accurate characterization. But as technology continues its journey toward commercial production, ensuring an accurate power rating without slowing down the manufacturing process presents a new challenge both for suppliers of flash testing equipment and those working on bringing perovskite solar cells and tandem devices featuring them to market.
