The dynamic duo of silicon and perovskite continue their rampage through the solar cell industry. Researchers at KAUST have developed a new silicon/perovskite tandem solar cell with a record-breaking efficiency.

It's always a shame when you buy fresh produce, only to have it spoil in the fridge before you can use it. The Aurora system is designed to keep that from happening, using a combination of ultraviolet light and vacuum packing.

In remote desert locations, at least two things are likely to be lacking: an electrical grid, and a source of water for agriculture. An experimental new system addresses both problems, by combining photovoltaic panels with an absorbent hydrogel.

The burning of coal may be falling out of favor as a means of generating heat and electricity, but that doesn't mean the material no longer has any valuable uses. According to a new study, it could be utilized in the desalination of seawater.

There are many parts of the world that lack infrastructure, but that get a lot of sunlight ... which makes buildings hot. A new system could help, as it uses a combination of sunlight and salt water – but no electricity – to produce a cooling effect.

The ocean holds billions of tons of lithium, and scientists have just tested a new way of extracting it, with a device that takes in seawater and pumps out freshwater and lithium phosphate – plus more than enough H2 and chlorine to pay the power bill.

Making every micrometer count is a key consideration for designers and engineers working on modern smartphones, and a new nanometer-thick form of graphite that helps keep electronic devices cool could free up some valuable space.

New ultrathin solar cells boast a few advantages over others of their type. They're more efficient, made using more common elements, and can be inkjet-printed onto surfaces, making them light and flexible enough to power wearable electronics.

A highly porous and recyclable mat developed at Saudi Arabia’S King Abdullah University of Science and Technology (KAUST) could mean good things for the environment, with its creators reporting it can adsorb oil with great efficiency.

An international team of scientists has created a new type of solar flow battery that’s efficient and long-lasting. The device is made up of a silicon/perovskite tandem solar cell, paired with a redox flow battery, with organic chemical electrolytes.

Radio waves travel poorly through the water, which makes it difficult for divers or submersibles to wirelessly transmit information to the surface. Scientists are trying to change that, though, by developing an underwater version of Wi-Fi.

Given that solar panels lie in direct sunlight, it goes without saying that they can get pretty hot. Unfortunately, though, they also get less efficient as they heat up. That said, a new gel could help cool them … without using any electricity.
