All-perovskite tandem solar cells, stacks of p-n junctions formed from perovskites with different energy bandgaps, have the potential of achieving higher efficiencies than conventional single-junction solar cells. So far, however, most proposed all-perovskite tandem cells have not achieved the desired power conversion efficiencies (PCEs), often due to difficulties associated with creating suitable narrow-and wide-bandgap subcells.

Researchers at Nanjing University and University of Toronto recently developed new inorganic wide-bandgap perovskite subcells that could increase the PCEs and stability of these promising solar cells. Their design, introduced in a paper in Nature Energy, involves the insertion of a passivating dipole layer at the interface between organic transport layers and inorganic perovskites within the cells.

“Our research group has been focusing on improving the PCEs of all-perovskite tandem solar cells, which have broken the world record several times and have been included in the ‘solar cell efficiency tables,’” Hairen Tan, one of the researchers who carried out the study, told Tech Xplore.

But now we’re learning that researchers in Sydney may have found a way to tackle this issue.

Sorry I’m not that active. My mom had a heart attack a little over a month ago and I care for her now. Plus last Thursday I went to the ER for overdosing accidentally on depakote which can be deadly. But check this out. In case of an emergency is this cool or what? Kind of expensive though.

If this summer you’re in the mood for some off-the-grid camping trips, this state-of-the-art self-sustainable luxury trailer is what you need. Designed from the ground up for off-grid camping, the trailer can also produce its own water, making it fully self-sufficient. This extremely sophisticated camper is the work of a California-based company called Living Vehicle which specializes in making self-sustainable luxury travel trailers. The 2023 model was recently introduced by Living Vehicle and it boasts a few industry firsts.

According to its makers, the off-grid camper is aimed at those who wish “to travel far away from campgrounds and overcrowded RV parks.” With a starting price of $340,000, the luxury camper is available in three versions: Core, Max, and Pro. Additionally, Living Vehicle offers a laundry list of options that can be added to the camper via the company’s online configurator.

Stirling converters could allow deep space missions to massively reduce their reliance on potentially scarce solar energy.

China’s Shenzhou-15 mission crew aboard the China Space Station (CSS) has reportedly completed testing on a free-piston Stirling thermoelectric converter, according to a report from state-owned media in China.

The vessel goes by the name of Domus, which means “house” in ancient Latin.

Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light.

The structure, which naturally occurs in the wing scales of some species of butterfly, can function as a photonic crystal, according to a new study by researchers at the University of Birmingham. It can be used to control light in the visible range of the spectrum, for applications for lasers, sensors, and also devices for harvesting solar energy.

Their computational study, published in Advanced Materials, demonstrates that the complex gyroid structure can be self-assembled from designer colloidal particles in the range of hundreds of nanometers.

In 1960, visionary physicist Freeman Dyson proposed that an advanced alien civilization would someday quit fooling around with kindergarten-level stuff like wind turbines and nuclear reactors and finally go big, completely enclosing their home star to capture as much solar energy as they possibly could. They would then go on to use that enormous amount of energy to mine bitcoin, make funny videos on social media, delve into the deepest mysteries of the Universe, and enjoy the bounties of their energy-rich civilization.

But what if the alien civilization was… us? What if we decided to build a Dyson sphere around our sun? Could we do it? How much energy would it cost us to rearrange our solar system, and how long would it take to get our investment back? Before we put too much thought into whether humanity is capable of this amazing feat, even theoretically, we should decide if it’s worth the effort. Can we actually achieve a net gain in energy by building a Dyson sphere?
