Role of UV in solar cell degradation
US scientists have tested a range of modern cell designs under strong ultraviolet light and have found that many of them, including p-type PERC and n-type heterojunction cells, are more susceptible to degradation than older back surface field designs. They noted that the rear side of bifacial cells may be particularly vulnerable.
Chinese PV Industry Brief: Longi, Shenzhen Energy partner on inverters
Longi has revealed plans to enter the inverter business through a partnership with Shenzhen Energy, while Solarspace has announced plans to open a 16 GW cell factory in Anhui province.
Photovoltaics and anaerobic digestion
Researchers in Egypt have studied the use of solar power and anaerobic digestion for a 6,300-square-meter farm capable of housing 200 head of milk/beef cattle. They found that this combination could achieve a cost of energy of $0.0226/kWh.
Chinese manufacturer unveils 210 mm busbarless heterojunction solar module
China’s Cando-solar Photoelectric Technology said its newest solar panel has a power output of up to 425 W and a power conversion efficiency of up to 22.1%. Its temperature coefficient is -0.24% per degree Celsius.
US lifts tariffs on solar products from Canada, Mexico
Canada, the United States, and Mexico signed an agreement to lift Trump-era tariffs, after an independent panel said that the duties violated the provisions of existing trade agreements.
pv magazine Roundtables: Videos on EU manufacturing, solar sustainability, decarbonizing homes, and PV on wheels sessions
With a strong focus on solar and battery energy storage and their role in decarbonization right throughout the European continent and economy, this year’s pv magazine Roundtables Europe focused on how green electrons, jobs, and manufacturing can deliver a cleaner, freer future for Europe. The first five sessions are now available to view on demand.
Management system combines rooftop PV, heat pumps
Swiss startup Solar Manager AG has designed a new energy management system that is compatible with the inverters of Solaredge, Solax, Kostal, Fiemer, Fronius, and other manufacturers.
Environmental impacts of perovskite PV
A life-cycle analysis of perovskite-silicon tandem modules indicates that additional environmental impacts in manufacturing are more than offset by the higher energy yield over their lifetime.
The stabilizing effect of vertical east-west oriented PV systems
German researchers have looked at how vertical PV systems could provide more electricity during periods of higher demand, while enabling a higher level of integration with agricultural activities.
A single solar panel can offset the carbon emissions of 10 trees
Using broad average values of 48.5 pounds of carbon sequestration per year for a mature tree, versus 0.85 pounds of emissions offset per kilowatt-hour of solar electricity, it’s clear that some tree clearing is acceptable from an emissions standpoint.
