Assessing PV cell, module reliability via Arrhenius equation
Researchers in Portugal have used the so-called Arrhenius aging model to measure the temperature behaviour and reliability of different solar modules. Their analysis showed that long-term module performance can diverge significantly depending on the manufacturing processes.
Dexter Energy adds battery support to forecasting, PV power optimization platform
The Dutch company says its short-term trading solutions for solar and other renewable energy technologies, supports grid balancing, reduces the costs of imbalance, and optimizes energy flows in an “increasingly volatile” energy market. It is growing internationally, and expanding its support of battery-related trading.
A closer look at vertical agrivoltaics
pv magazine visited a 1.9 MW agrivoltaic plant in Austria where pumpkins and soy are cultivated beneath vertically mounted PV structures supplied by Next2Sun.
Four-year outdoor testing shows perovskite solar cells suffer from high seasonality
Testing conducted by the Helmholtz-Zentrum Berlin (HZB) in Germany has shown that perovskite solar cells operating at high latitudes in Europe may suffer from higher performance losses in winter compared to conventional PV devices. The scientists warned, however, that at lower latitudes this seasonality may be less pronounced.
NREL, CubicPV achieves 24% efficiency for perovskite mini solar module
A U.S.-based collaboration between the National Renewable Energy Laboratory (NREL) and CubicPV has yielded a perovskite minimodule with certified efficiency of 24.0%. The two noted that it is the first time a U.S. effort has set a record in the perovskite mini module category.
Superdielectrics unveils Faraday 2 battery as a polymer-based alternative to Li-ion
Superdielectrics launches the Faraday 2 battery, advancing a water-based, metal-free approach to home storage, from a UK-based facility.
Researchers discover method to significantly extend quantum battery lifespan
Researchers at the Royal Melbourne Institute of Technology (RMIT University) and Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) have developed a way to extend the lifetime of Dicke quantum batteries by up to 1,000 times, while maintaining their fast-charging properties enabled by superradiance.
New PV system sizing approach based on jellyfish search algorithm
Researchers have used the jellyfish search algorithm to optimize solar PV distributed generation placement and sizing. They have tested the algorithm on an IEEE 33-bus system, with one, two, or three PV deployment scenarios, and compared its performance with that of a dozen of competing optimization techniques.
PVRadar launches Python programming tool to ease site-specific loss modeling
German software company PVRadar Labs has released a Python programming package for solar asset owners and engineers that want to build site-specific models.
