Canadian researchers have recently developed a low-cost, new bio-solar cell that uses E. coli to convert light into energy. The battery produces a higher current density than previous batteries of the same type, and works in dim light with comparable brightness in bright light.

It was learned from Nankai University that the team of Professor Chen Yongsheng of the school made a breakthrough in the research of organic solar cells, which made the conversion efficiency of organic solar cells reach 17.3%.

China's National Day, marking the 75th anniversary of the founding of the People's Republic of China, was celebrated with grandeur and enthusiasm across the country. Festivities included magnificent parades, vibrant cultural performances, and dazzling fireworks displays. Citizens adorned their homes and streets with national flags, expressing their patriotism and pride. The holiday also witnessed a surge in tourism, with many taking advantage of the long break to explore the nation's scenic spots. This year's celebration underscored China's remarkable progress and unity among its people.

1. Light conditions Sufficient light: Please make sure to install the solar lights in a location with sufficient light and no blocking shadows on the light-facing surface of the solar panels throughout the day. This ensures that the solar panel receives direct sunlight, thus maximizing power generation efficiency. Avoiding Shadows: It is recommended to avoid installing solar lights in the shade of trees, near buildings, or in other areas that may create shadows. 2. Orientation and Angle Orientation: In the northern hemisphere, it is recommended that solar panels be oriented due south (can be slightly west of 5 degrees in order to better receive sunlight at about 1 o'clock in the afternoon, when power generation is usually higher). Angle Adjustment: For best results, adjust the angle at which the solar panel is tilted to the horizontal according to your local latitude.
