Researchers in China have reached an exciting milestone in solar energy efficiency, according to a recent report in Interesting Engineering.
Scientists associated with the Institute of Chemistry, Chinese Academy of Sciences have developed the next-generation solar cell, known as the perovskite-organic solar cell.
What makes this breakthrough so impactful is the cell's high efficiency. The perovskite-organic solar cell can reach a record photoelectric conversion efficiency of 26.4%, according to researchers on the team. This means it is able to convert more sunlight into usable energy.
The new findings underscore the potential of perovskite materials in supporting solar energy efficiency, as the conversion rates outperform existing solar cells. According to Sunsave, domestic solar panels have so far reached a top efficiency of 24%, with an average efficiency in the range of 18-24%.
The Chinese team was able to reach this level of efficiency by using wide-bandgap perovskite materials to capture short-wavelength sunlight. They then used a narrow-bandgap organic active layer, which absorbs near-infrared long-wavelength sun rays. Together, this combination significantly expands the usable solar spectrum, improving the device's overall efficiency.
Thanks to its lightweight material and simple preparation, perovskite solar cells offer numerous applications, including portable energy, building-integrated photovoltaics, and indoor photovoltaics, per Interesting Engineering.
In the energy industry, efficiency translates to reduced costs. So by improving solar cell efficiency, the researchers are decreasing the cost of solar energy for commercial and home use.
Switching to solar energy can lead to significant monetary savings down the road. After initial installation costs, you can expect annual savings of up to $1,500.
You'll not only lower your utility bills, but you'll also reduce your environmental footprint when you add solar panels to your home.

Solar panels are carbon neutral, so after installation, they won't emit any pollution into the atmosphere. Thus, your home will push less planet-warming gas into the atmosphere, significantly reducing your household's carbon impact.
Moving forward, the researchers will continue to study perovskite material with the goal of developing the best method for improving device stability and increasing open-circuit voltage.
