Scientific articles
Organic photodiodes with bias-switchable photomultiplication and photovoltaic modes - Open Access
The limited sensitivity of photovoltaic-type photodiodes makes it indispensable to use pre-amplifier circuits for effectively extracting electrical signals, especially when detecting dim light. Additionally, the photomultiplication photodiodes with light amplification function suffer from potential damages caused by high power consumption under strong light. Read more…
Georectified polygon database of ground-mounted large-scale solar photovoltaic sites in the United States - Open Access
Over 4,400 large-scale solar photovoltaic (LSPV) facilities operate in the United States as of December 2021, representing more than 60 gigawatts of electric energy capacity. Of these, over 3,900 are ground-mounted LSPV facilities with capacities of 1 megawatt direct current (MWdc) or more. Ground-mounted LSPV installations continue increasing, with more than 400 projects appearing online in 2021 alone; however, a comprehensive, publicly available georectified dataset including spatial footprints of these facilities is lacking. The United States Large-Scale Solar Photovoltaic Database (USPVDB) was developed to fill this gap. Read more…
Solar neighborhoods: the impact of urban layout on a large-scale solar strategies application - Open Access
The article addresses the challenges of evaluating energy performance in different neighborhood settings under various energy efficiency measures and proposes a methodology for selecting appropriate solar strategies on a neighborhood scale. The study selects five representative neighborhoods from various climatic zones with different building and street layouts. The proposed methodology involves a systematic three-step multi-domain workflow for implementing energy efficiency measures and solar strategies in the existing neighborhoods. The first step involves typical energy performance simulation, the second step involves energy simulation using high performance building envelope, and the third step involves the addition of solar strategies in combination with retrofitting materials to achieve net-zero status… Read more…
Sensor platform for assessment of water usage patterns in informal settlements - Open Access
Rapid urbanization has intensified pressures on global water systems, particularly impacting informal settlements. Understanding water usage patterns within these settlements is of importance for better addressing water scarcity issues. Current methods for gaining information about water within these settings tend to lack spatio-temporal granularity and miss complex patterns of behavior related to water usage. As a consequence, there is a shortage of the reliable quantitative measurements needed to improve water management processes and modeling. Read more…

Climate influence on compound solar and wind droughts in Australia - Open Access
Solar photovoltaic and wind power are central to Australia’s renewable energy future, implying an energy sector vulnerable to weather and climate variability. Alignment of weather systems and the influence of large-scale climate modes of variability risks widespread reductions in solar and wind resources, and could induce grid-wide impacts. We therefore systematically analyse the relationship between compound solar radiation and wind speed droughts with weather systems and climate modes of variability over multiple time scales. We find that compound solar and wind droughts occur most frequently in winter, affecting at least five significant energy-producing regions simultaneously on 10% of days. Read more…
Réunion’s search for energy self-sufficiency - Open Access
Valentin Russeil was studying in Paris in 2018 when protests against the rising cost of living and 24% unemployment broke out on the island of Réunion. The island is an overseas department of France, located east of Madagascar. Russeil, who is from Réunion, followed the news closely and spoke to his family back home every day. He was disturbed to learn that the island’s docks had been blocked by protesters, preventing the import of food and fuel. “Things started to disappear very, very quickly,” he says. “My family had to start doing everything with bicycles, not gas.” Read more…
Wind-driven device for cooling permafrost - Open Access
Preserving permafrost subgrade is a challenge due to global warming, but passive cooling techniques have limited success. Here, we present a novel wind-driven device that can cool permafrost subgrade by circulating coolant between the ambient air and the subgrade. It consists of a wind mill, a mechanical clutch with phase change material, and a fluid-circulation heat exchanger. The clutch engages and disengages through freezing and melting phase change material, while the device turns off when the outside air temperature exceeds a certain threshold, preventing heat from penetrating the subgrade. Two-year observations demonstrate that the device effectively cooled permafrost measuring 8.0 m in height and 1.5 m in radius by 0.6–1.0 °C, with an average power of 68.03 W. Read more…
Energy Harvesting and IoT Market opportunities
Ambient Light Harvesting Heads Indoors
“What the world needs now is to expand the scope of energy harvesting” by tapping indoor ambient light sources, said Matthias Kauer, CEO and co-founder of Lightricity (Oxford, U.K.). “We have this proliferation of battery-powered devices for industrial automation, building automation, etc. They require a solar cell with high efficiency at all light levels, down to very low light levels. The thing with light harvesting is that, in most cases, you don’t have control over the environment.” Read More…
Electrification Outside Automotive: A Trillion Dollar Market
The automotive sector is rapidly electrifying, with electric car sales totaling over 5.8 million units in the first half of 2023 across China, Europe, and the US. While automotive electrification is at the forefront of the public eye, other vehicle sectors also present huge opportunities, with IDTechEx predicting the global market of electric vehicles for land, sea, and air to be worth over US$1 trillion in 2044 (excl. automotive).

Tiny worn devices won’t need batteries thanks to these innovations
Wearable devices, like nearly every other piece of tech, need energy. Fortunately, though, at wearables’ modest power budgets, energy is effectively everywhere. It’s in the sun’s rays and radio waves, the skin’s sweat and body heat, a person’s motion and their footfalls. And today, technology is maturing to the point that meaningful amounts of these energy giveaways can be harvested to liberate wearables from ever needing a battery. Which seems plenty attractive to a range of companies and researchers. Read More…
