Spray On Solar Cells

cells

A team of researchers at the University of Sheffield in the UK have found a way to make a spray-on solar cell, which has perovskite as the light-absorbing layer. This new cell’s efficiency is only 11 percent, but it can be produced very cheaply, which could be the first step forward in large scale production of affordable solar panels.

Listening to Plants

Plants, just like humans and animals, have a way of communicating with each other. Their language is comprised of electrical signals, through which they send messages to other plants. And now an international group of scientists is developing a way to analyze these electrical signals, and translate them into information we can understand. The project is called PLEASED (PLants Employed As SEnsing Devices) and has already received €1.07 million ($1.46 million) in EU funding.

When looking into off-the-grid heating and power sources for the home, those interested might soon be getting a new option. The Dresden, Germany-based Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) has joined forces with the heater manufacturer Vaillant and together they have come up with a domestic fuel cell system, which uses natural gas to produce both heat and electricity.

Researchers at Northwestern University have developed a new solar cell that uses tin instead of lead perovskite as a collector of solar energy. This cheap and environmentally-friendly solar cell can therefore be made without any high-tech equipment or hazardous materials.

Two Russian scientists, Leonid and Sergey Plekhanov, both of the Moscow Institute of Physics and Technology (MIPT) are trying to crowdfund the building of a prototype of Nikola Tesla’s Wardenclyffe tower, which could allow for wireless transmission of power. Should they succeed, it is conceivable that the entire planet could be powered by renewable energy sources with very little energy loss during transmission.

Rooftop Mounted Wind Turbines That Make Homes Self-Sufficient

When it comes to renewable energy, wind turbines are certainly one of the greener and more sustainable options. Their biggest drawbacks is that they have to be large to produce enough energy, and that they make a lot of noise, which is why they haven’t yet been widely adopted by homeowners. However, The Archimedes, a Holland-based renewable energy start-up is currently working on a solution to this problem. They are designing a wind turbine small enough to be mounted on the roof of a typical home, but which is still highly efficient at converting wind to energy and does so nearly soundlessly.
