The physicist organization network reported on the 19th that the British and American multinational teams have used theories and experimental methods to successfully apply the “green elements” of the periodic table to low-cost solar cells, and the light conversion efficiency has reached the highest level in the current market, and avoided. The toxicity of lead-based batteries. This major progress was published in the latest issue of Advanced Materials magazine.

The main material of most solar cells currently covered on the roof is silicon, although it is more efficient in the conversion of light and energy, it must ensure very high purity in order to carry out dense energy conversion, but this feature makes it The cost of production remains high.

Over the past few years, researchers have been looking for similar or better alternative materials. The most promising combination is the "mixed lead halide perovskites," which have the advantages of being cheap, easy to produce, and as efficient as silicon, and they seem to be able to Leading the revolution in the field of solar cells. However, perovskite solar cells have been controversial in the scientific community because lead in these batteries may pose a real hazard to humans, animals and the environment. For this reason, scientists engaged in the research of solar cell materials all over the world have never stopped looking for new nontoxic materials and hope to replace lead in perovskite solar cells.

This time, a team of researchers from Cambridge University’s Cavendish Laboratory in the United Kingdom, the Massachusetts Institute of Technology in the United States, the National Renewable Energy Laboratory in the United States, and the Colorado School of Mines found that plutonium adjacent to lead in the periodic table may be Instead of it. Although it is a heavy metal, it is non-toxic and is a "green element". It is widely used in cosmetics, personal care products and medicines.

The results of the research team showed that ytterbium iodate can remain stable in the air for up to 197 days, which is significantly better than lead-halogenated perovskites. Researchers believe that solar cell components based on germanium can use conventional industrial technologies for low-cost and large-scale manufacturing. (Reporter Fang Linlin)
