Technology and R&D

Researchers at the University of South Carolina have successfully transitioned their highly-durable lithium-sulfur battery technology from coin to pouch cells and reported competent energy densities.

Researchers in Nigeria have proposed to build inverted perovskite solar cells exclusively with all-inorganic transport materials and a lead-free perovksite absorber. Through a series of simulations, they showed these device may achieve efficiencies over 30% with low production costs.

U.S. scientists have developed a thermophotovoltaic cell that could be paired with inexpensive thermal storage to provide power on demand. The indium gallium arsenide (InGaAs) thermophotovoltaic cell absorbs most of the in-band radiation to generate electricity, while serving as a nearly perfect mirror.

The versatility of solar mounting manufacturer and balance-of-system provider Clenergy’s ezShade 2.0 solar shade system has been put to the test with the solution at the core of a standalone power system fuelling an off-grid communications site in remote northern Queensland.

Perovskite PV devices are set to become the next big thing in solar with market analysts at S&P Global Commodity Insights predicting 1 GW of production by the end of 2024, rising to 6 GW in 2025. Perovskite tandem devices are at the front of the queue for commercialization but their characterization presents technical challenges.

Developer Loop Energia has built a 1.2 MW offgrid solar plant that now serves a center-pivot irrigation system in the Brazilian state of Bahia. The project reportedly enables local farmers to double soybean harvesting by achieving considerable savings through significantly lower diesel consumption.

In a new weekly update for pv magazine, Solcast, a DNV company, explains that the solar cycle does tend to increase the earth’s average annual extra-terrestrial irradiance, but only by a very small amount. It also explains that, while the annual cycle of extra-terrestrial irradiance causes a steady, predictable and significant 3.5% change through the seasonal cycle, the peak of the 11-year cycle of solar activity causes a smaller, more sporadic and unpredictable set of fluctuations.

Visionpark said its novel solar carport solution is self-weighted and requires no foundation. It can reportedly host all kinds of solar panels and be installed quickly.

An international research group has utilized a newly designed coalitional game system to ensure economic fairness between members of energy communities. The game system considers different types of prosumers relying on stand-alone and combinations of solar and storage.

Novel research from Germany and the USA has analyzed the impact of heat pump (HP) integration on the ability of day-ahead load forecasting in energy communities. Using different models, the scientists have also investigated whether HP loads should be forecasted separately from the rest of the household or both together.
