Scientists develop groundbreaking technology that could slash household energy bills: 'New possibilities'

During hot and cold conditions, windows can play a major role in determining a home's overall energy efficiency. Scientists have now developed groundbreaking technology that could not only improve a window's ability to retain temperature but also create energy.

A team led by researchers from Hong Kong Polytechnic University developed high-efficiency, semitransparent organic photovoltaic (ST-OPV) "smart windows" with enhanced thermal insulation and operational stability, per Tech Xplore. The combination could give homeowners a chance to save on their energy bills.

In a study first published in Nature Communications, the researchers developed a new parameter, FoMLUE, to evaluate and select the best photoactive materials by considering average visual transmittance, bandgap, and current density. This breakthrough enables solar power generation from smart windows while also improving a building's energy efficiency.

"As an emerging solar photovoltaic technology, solar windows offer new possibilities for practical deployment in BIPV [building-integrated photovoltaics], renewable energy vehicles, and agricultural greenhouses," said Li Gang, chair professor of Energy Conversion Technology at Hong Kong Polytechnic University and co-author of the study.

"Our findings highlight the multifunctionality and geographical adaptability of high-performance ST-OPVs in the construction of sustainable and energy-saving smart windows without compromising the integrity of architectural design, showcasing their highly promising commercial prospects," added Gang.

Energy-efficient windows can be a crucial component to a home's energy efficiency because of their ability to reduce heating and cooling costs. This can be done by minimizing energy loss, allowing heating and cooling systems to work less, which can help lower their operating costs while also reducing your reliance on planet-heating fossil fuels.

While solar energy-capable windows may still be a ways away from commercial production, the installation of solar panels can help bring your cost of energy down to or near $0, making it one of the most effective energy hacks out there. You can check out TCD's Solar Explorer to connect with vetted installers and save up to $10,000 on solar installations by comparing competitive bids.

Solar Explorer also has $0 down subscription program that can cut down your utility rates by up to 20%. This includes Palmetto's LightReach solar panel leasing program, which lets users lock in low energy rates.

Not to be outdone, pairing solar panels with an upgraded HVAC system can also help you save an average of nearly $400 a year on energy costs. Check out TCD's HVAC Explorer to find the right affordable heat pump that is perfect for you and your home.
