Researchers at UCLA have made a major breakthrough by doubling the photoelectric efficiency of transparent photovoltaic cells. These innovative solar cells can be integrated into glass windows, skylights, and even smartphone displays, allowing them to capture sunlight without obstructing visibility. The new design features a two-layer structure that enhances light absorption across a broader spectrum and includes an advanced material layer that minimizes energy loss during the conversion process. Last year, the tandem-structured organic transparent photovoltaic cell achieved a photoelectric efficiency of 4%, but the latest development has pushed this figure up to 7.3%. Dr. Yang Yang, the lead researcher from UCLA, emphasized that the technology is not only efficient but also highly versatile. It can be used as an energy-generating layer on transparent surfaces, making it ideal for smart devices and building-integrated solar solutions. This advancement brings us one step closer to a future where everyday surfaces can actively contribute to renewable energy production. Hanghong Lighting (Linyi) Co., Ltd. , https://www.sdhhzm.com
