Solar panels, wind turbines, geothermal energy, thermoelectric, and wave energy are all renewable sources of energy that utilize what the environment provides. Renewable sources of energy have been in the imagination of every scientist since oil became a problem for the planet. The carbon emissions harm the planet’s atmosphere, destroying the ozone layer, which is responsible for protecting Earth from the sun’s UV radiation. With this in mind, a new indoor solar panel strip was created to power objects.
Renewable sources of energy are a reality
The need to power houses, cellphones, computers, and personal devices is rising with the adoption of hybrid or total remote jobs, as well as vehicles with hybrid or full electric powertrains. One of the main sources for this is using solar energy to charge and light up what the user needs. Many houses in sunny places like Arizona, Las Vegas, and California use one of their biggest characteristics to transform into energy.
After years of many homes adopting solar panels to create hybrid or full-powered energy lines, researchers in the private sector are starting to develop new technologies to see what else can be powered by light.
Australian company develops an indoor solar panel
The Australian startup Halocell developed photovoltaic strips able to convert indoor light into electricity. The company started producing the flexible 7-centimeter photovoltaic strip capable of generating enough power to replace small, yet powerful sources of energy, such as batteries from a TV remote or a charging unit for a set of headphones.
The invention represents the first large-scale manufacturing in Australia of a technology considered the future of cheap energy. This creation of the device was only possible because of the discovery of a new solar cell called perovskites, with the potential to be more efficient, cheaper, and perform better than conventional silicon cells.
On the other hand, to make these cells durable enough to hit the market, researchers have gone through a long and difficult period. After years of work, the first commercial cells are emerging, but they are specifically designed for niche markets like consumer electronics and satellites.
How does the product work?
When sunlight hits a panel – usually made of silicon – it shakes things up inside the material and knocks some electrons loose. That movement of electrons is what creates the electric current we end up using to power things. However, for that to happen, the light needs to hit with enough energy. There’s a minimum amount called the “bandgap.” If the light doesn’t reach that level, nothing happens. And if it goes over, the extra energy is just lost as heat – it doesn’t help make more electricity.
Halocell’s perovskite cells operate at 27% efficiency in low indoor light, according to the company. Even the best silicon solar panels out there today convert only about 27% of sunlight into energy. The limit is around 32%. That might sound low, but at the scale these panels are used worldwide, even a small boost makes a big difference.
The industry is heading toward efficient renewable energy sources
That’s where perovskites come in. This new material is opening the door for solar panels that can catch more sunlight by being layered in smart ways, driving strong interest in perovskite cells as the next step in clean energy. Renewable sources of energy are coming full circle with this invention. If a house or building is powered by solar panels that light up the structure, the same light that’s being generated by the sun will be charging another source of energy.
