Spherical monocrystalline solar cells with 18.93% efficiency
The spherical 3D cells can reportedly generate around 101% more power than conventional flat solar cells. Measurements have also shown that the spherical cells provide a 10% lower maximum temperature compared to flat cells, while accumulating less dust.
Scientists in China give flexible perovskites a backbone
A team of researchers led by Nanchang University in China trialed a polymer based hole transport layer to flexible perovskite solar cells, using a glue to attach it to the active perovskite. The team was able to assemble the 19.87%-efficient cells into a small flexible module suitable for wearable solar applications, and says its design was inspired by the structure and movements of human vertebrae.
Volkswagen invests up to US$200 million in solid-state battery builder QuantumScape
This investment comes on top of US$100 million invested in 2018. Venture capital and corporate funding of new energy technologies continues despite – or perhaps because of – the pandemic.
Deploying rotating PV arrays on cooling towers
Swedish researchers have proposed the installation of rotating and revolving PV arrays on the cooling towers of thermal power plants. While such projects are ideal in nations with limited land, installation costs are also cheaper than for ground-mounted or rooftop PV plants due to proximity to the grid, the scientists claim.
Mobile solar pumping system offers pay-as-you-go solution for Indian farmers
Researchers have simulated a cart-mounted solar pump which they say would mean farmers in off-grid areas would be able to irrigate fields by paying only for the solar electricity used.
PV-electrochemical water-splitting for hydrogen production
A German research team has developed a new photovoltaic-electrochemical device for alkaline water electrolysis. The prototype has an initial solar‐to‐hydrogen efficiency of approximately 7.7%.
Battery performance standard for residential and commercial applications
Researchers have proposed a new battery performance standard for Australia and possibly the world. If adopted, the standard could clarify consumer confusion around which energy storage system is right for them.
Hydrogen storage in salt caverns
Researchers in Germany have identified salt caverns as a feasible and flexible solution for hydrogen storage. They also revealed that Europe has the potential to inject hydrogen in bedded salt deposits and salt domes, with a total storage capacity of 84.8 PWh.
CIGS solar cell with IBC structure and up to 19.7% efficiency
Scientists in the Netherlands have demonstrated an interdigitated back contact copper-indium-gallium-selenide solar cell with a sub-micron thickness of 673nm. The device has an aluminum oxide and magnesium fluoride-based anti-reflective coating.
New approach to energy management in microgrids
Researchers from Australia’s Monash University have developed an energy exchange framework to manage distributed energy resources and help consumers lower their power costs.
