瑞典科学家利用造纸工业的废弃物制造出太阳能电池的阴极,该阴极能采用一种更加智能更加廉价的方法存储太阳能,使得人们能持续从太阳能电池和风涡轮机获得廉价的电力。研究论文发表在《科学》杂志上。传统电池使用金属氧化物导电,但这些金属材料非常稀缺;而用导电塑料制成的有机太阳能电池虽然成本较低、性能好,足以进行商业化生产,极具竞争优势,然而,太阳能电池必须要将其产生的电从早存储到晚,风涡轮机产生的电力也必须存储起来等到无风的日子使用,因此,科学家们一直研究用低廉价格且可再生的材料来制造电池的阴极。 Swedish scientists use paper industry waste to create the cathode of a solar cell that can store solar energy in a smarter and cheaper way, enabling people to continue to get cheap electricity from solar cells and wind turbines. Research paper published in “Science” magazine. Conventional batteries use metal oxide as a conductive material, but these metal materials are very scarce; while organic solar cells made of conductive plastic have a competitive advantage in terms of low cost, good performance and commercialization, however, solar cells have to Since the stored electricity is stored from the earliest to the late, wind turbines generate electricity that must be stored for windless days. As a result, scientists have been investigating the fabrication of battery cathodes using inexpensive and renewable materials.
