Metal can also help photovoltaic development and effectively improve energy absorption

        Solar cells convert solar energy into electrical energy through the photoelectric effect. Therefore, the main direction of the company’s research team is how to increase the solar energy absorbed by the solar panels.

        Externally, users will choose to build solar power stations in areas with plenty of sunshine and long hours of sunshine, and at the same time, supplemented by intelligent tracking brackets, the algorithm can track the sun to the maximum extent to increase power generation.

        Internally, materials with higher conversion efficiency will be used, and through advanced battery technology, as much sunlight as possible will be converted into electricity.

        Recently, scientists at the University of Rochester in the United States have taken a different approach and proposed a way to convert metals into solar absorbers.

        It is reported that the team used lasers to create fine lines in nano-scale structures. The etched metal surface can absorb sunlight well, thereby helping to expand the absorption method of solar energy. It is also very similar to the familiar photovoltaic principle, which may give The development of photovoltaics opens up new ideas.

        At present, solar cells use silicon-based materials as the cells, and use photovoltaic glass, adhesive films and frames and other auxiliary materials for packaging to form the solar cell modules we have seen. Cost reduction is also mainly based on these materials, and continuously reduce costs, thereby reducing the cost of the entire module, so that photovoltaics have achieved rapid development.

        However, due to the recent rise in the price of upstream silicon materials, which has driven up the price of mid-and downstream materials, the price of modules has naturally risen. This is undoubtedly a reversal after photovoltaics entered the era of parity. This time, the American scientific research team put forward the idea of ​​using metal to attract solar energy, which may provide some enlightenment from the Chinese scientific research team.
