Cambridge Scientists Discover Organic Material That Could Revolutionize Solar Energy
—————————-
Researchers at the University of Cambridge have discovered an organic material capable of converting light into electricity with nearly 100 percent efficiency, a finding that could significantly lower the cost and complexity of solar panel production, Anadolu Agency reported.

According to Cambridge University’s Department of Physics, the newly identified compound—called P3TTM—is an organic semiconductor containing unpaired electrons that enable highly efficient charge transfer. Unlike conventional solar cells that require two materials (one to donate and another to accept electrons), P3TTM alone can separate electrical charges upon light absorption.

As Open Access Government reports, this property is due to the material’s quantum behavior resembling that of a Mott-Hubbard insulator, a feature typically seen only in inorganic substances. Lead scientist Biwen Li described the process as “the real magic,” emphasizing that it could simplify production and dramatically reduce costs by eliminating several fabrication steps.

According to Anadolu Agency, this innovation could make solar technology cheaper, lighter, and more adaptable for portable or flexible applications. It may also pave the way for new uses in consumer electronics and renewable infrastructure.

While the Cambridge team cautions that further testing is needed to ensure long-term stability and scalability, experts believe this marks a new era in solar research. As Cambridge University reports, the finding could lead to the world’s first single-material organic solar cells—a major step toward more sustainable, efficient, and accessible renewable energy systems.
