Sunrise brief: Solar panels: Larger, thinner… and weaker?
Also on the rise: TOPCon risks. Positive early results from first test of perovskite tandem solar cells in space.
Positive early results from first test of perovskite tandem solar cells in space
The perovskite-silicon and thin-film tandem solar cells were developed by Helmholtz-Zentrum Berlin and placed on an OOV-Cube small satellite to test their reactions to high levels of radiation—and whether “soft” perovskite solar cells can heal after taking on radiation damage.
‘TOPCon technology comes with three or four relevant risks that should be known’
The results of this year’s Kiwa PVEL scorecard show that TOPCon technology is more vulnerable than PERC, and the failure rate at BOM level has increased to 41%, the highest in history, according to the testing lab.
Solving the UV problem of n-type solar
Laboratory testing has revealed that some negatively-doped, “n-type” tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) solar modules are susceptible to ultraviolet (UV) light-related damage and degradation. That could mean trouble down the line, if modules in the field begin to show UV-related performance loss. Manufacturers are implementing solutions at cell and module level.
Two utilities share their experience with reconductoring that can enable more solar
While replacing existing transmission lines known as conductors with advanced conductors could enable 764 GW of transmission-connected solar by 2035, some utilities are slow to adopt the technology. Two utilities that have used advanced conductors for years shared their experiences on a webinar.
Powering restaurants with rooftop PV, reversible fuel cells
Researchers have simulated the operation of bifacial PV and proton exchange membrane reversible fuel cells across restaurants in five different U.S. states. Taking into account varying rates of bifacial PV’s rearside gains, they found that LCOE was as low as $0.029 per kWh.
California farmers developing 20 GW solar-plus-storage plan
The Golden State recently signed AB 2661, granting the Westland Water District authority to develop transmission lines that will enable solar energy and storage projects on 130,000 acres of drainage-impaired farmland.
Researchers capture first-ever images of electric charges across semiconductor materials within a solar cell
A team from the University of California Santa Barbara used ultrafast electron microscopy to record photocarriers as they diffuse across a silicon and germanium heterojunction. It is the first time the movement, which lasts picoseconds, has been captured as a moving visual.
U.S. solar generation strong outside Hurricane Milton’s localized impacts
In a weekly update for pv magazine, Solcast, a DNV company, reports that the impact of Hurricane Milton on solar production will be minimal outside the southeastern United States, as the system quickly moves offshore.
Sunrise brief: IEA forecasts over 4,000 GW of new solar by 2030
Also on the rise: Form Energy raises $405 million for its multi-day iron-air batteries. Bipartisan initiative to accelerate deployment of distributed energy resources in U.S. And more.
