Scientists Combine Solar Cell and Battery into a Single Highly Efficient Package

solar-cell-battery (1)

A team of researchers at the Ohio State University (OSU) successfully produced a dye-sensitized solar cell, which can store power by using air to decompose and re-form lithium peroxide. This device combines a solar cell and battery into one, and it is the first device of its kind. The adoption of this technology could also considerably lower the costs of solar cells.

MIT Researchers Develop A More Efficient Battery

The more widespread adoption of renewable sources of energy is at least in part hampered by our poor ability to store energy. But a team of MIT researchers has recently a made a breakthrough in developing a new battery system. This all-liquid battery system is more efficient at storing energy, and costs less to produce, than currently available solutions. The further development of this system and use could make solar and wind energy more attractive and therefore facilitate its wide scale adoption.

Dr. Jon Major, a researcher at Liverpool University has recently made the discovery that the chemical used to make tofu, and bath salts, could also be used to replace one of the most toxic substances, namely cadmium chloride, that are used to manufacture solar cells. Using salts to replace cadmium chloride in solar cell production would also make them much cheaper. His study was published in the journal Nature.

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.

The photovoltaic technology is frequently used to obtain energy these days. Since it was discovered in the 19th century that it is possible to get energy from sunlight, the ways of harnessing solar energy went through many different stages. The first prototype of solar cells was, for example, used to provide the satellite Vanguard I with energy in 1958 and the technology has been used in this area ever since.

Energy Harnessed From Waves Could be on the Horizon

A team of researchers at UC Berkeley is developing a hydraulic seafloor ‘carpet’ that could be used to harvest the energy of ocean waves and convert it to usable clean energy. Since waves are constant, as opposed to sun and wind, this could prove a viable source of carbon-free energy for coastal regions. Wave energy is considered a huge potential source of renewable energy, but the systems for harnessing it are still very underdeveloped. Since there has been a rise in population in coastal cities this form of energy harvesting could prove a great, and, more importantly, clean source of renewable energy.
