Since the creation of the solar cell in the late 1800s, scientists and engineers have been fascinated with better harnessing the power of the sun. With so much potential, thousands of improvements have been made to solar technology. As we enter a new decade, solar proves to be the most affordable and accessible renewable energy source. With that in mind, let’s look into what’s new for solar panels and tech in 2020.
3 Major Improvements to Solar Panel Tech:
1. Better Solar Cells – The key component of any solar panel is the solar cell. Solar cells are found within the panels and convert the sun’s rays into electricity. Unfortunately, current solar cells perform at around 15% efficiency, meaning that 85% of the sun that hits the panels is not converted to energy. In order to boost cell performance in 2020, scientists are experimenting with new technology, including light sensitive nanoparticles and gallium arsenide.
2. Better and Cheaper Solar Panels – As solar cells improve, manufacturers are looking for ways to increase solar panel life, while decreasing overall panel cost. Rather than using traditional silicon semiconductors, manufacturers are seeking to incorporate magnesium chloride, a more unstable compound element, into the solar cells. Because magnesium chloride is an abundant resource extracted from the sea, its cheap and non-toxic.
3. Better Energy Storage – With solar panels becoming more powerful and efficient than ever, scientists are looking for a better way to store unused electricity. While there are batteries on the market, they are expensive, inefficient, and have a short shelf life. In 2020, several projects are underway to discover better ways of storing extra power, like Molten Salt Storage Technology and solar panels with built-in batteries.
3 New Solar Tech Devices in 2020
1. Solar Skin – Solar skin is a developing technology created by two MIT engineers that allows homeowners to customize the look of their panels. Rather than having aesthetically displeasing blue panels on their roof, or black panels on a roof that is not black, homeowners can now blend their panels with roof tiling, add patterns, and even incorporate art into their solar design!
2. Solar Fabric – For the first time, solar will become a part of our everyday clothing. With every fiber absorbing energy from the sun, solar fabric allows its wearer to produce electricity to charge a phone, keep warm, and have access to power on the go.
