<ul><li>A team of scientists in South Korea has developed new solar cells made with silver bismuth sulfide (AgBiS2), an eco-friendly and non-toxic material.</li><li>These solar cells are safer for the environment compared to traditional ones that use harmful metals like lead or cadmium.</li><li>The new technology increases the efficiency of the solar cells by 8.26%.</li><li>The researchers created a special thin film to address the issue of reduced performance when the light-absorbing layer becomes too thick, allowing the solar cell to capture more sunlight without losing efficiency.</li></ul>
