The experts in charge of the review of Applied Chemistry believed that Peng Huisheng's research team "realized photoelectric conversion and energy storage on a single fiber for the first time in the world" by using a "very simple and low-cost method", which greatly improved the utilization efficiency of solar energy, and "took a key step in the development of a full fiber energy system".

The design based on nano curvature is like stacking many small balls into a large ball. "The surface area increases from small to large, which is conducive to the rapid propagation of charges, thus greatly enhancing the conductivity of the material." Moreover, because carbon nanotube fibers have good flexibility, it will break the traditional "plane structure" of solar cells.

According to the experimental results, the highest photoelectric conversion efficiency of the newly developed solar cell exceeds 9%, but what should we do at night when we generate electricity during the day? "We are wondering whether we can integrate power generation and energy storage, use it when we want to use it, put it there when we don't want to use it, and store the rest." Therefore, using the same fiber material, Professor Peng's research group has constructed a miniature linear supercapacitor, which has successfully realized this idea.

In addition, the soft fiber battery is also braided. Peng Huisheng told the reporter, "Recently, we did a research on weaving solar cells into clothes. I hope that in the future, ordinary clothes can not only be bulletproof, but also generate electricity and store energy.".

Peng Huisheng said that the development of carbon nanotubes in energy is ahead of others, but it is still difficult to scale up production and large-scale preparation. "Because it is just starting, we should be able to solve these problems one by one through research". He said that he did not know how many years would elapse before electronic equipment made of these materials could be conveniently used. However, new materials are a very important driving force to change the whole society, and carbon nanotubes are a very interesting material. "It is just a beginning, opening up a new direction of development, and this road can be passed".
