A US-British research team reported that they used a new method to produce a perovskite solar cell, so that the photoelectric conversion efficiency approaches the traditional silicon-based solar cell, but there are a lot of costs. The perovskite material can be made into solar cells, and the photoelectric conversion efficiency is high. In recent years, the scientific community has always been optimistic about its prospects.
But it also has a performance unstable, easy to decay, and has no mature products. Researchers in Stamford University and Oxford University, the University of Oxford, produce new perovskite materials with several other common substances such as tin mixed lead, cesium, iodine. Compared with the current solar cell material single crystal silicon, this perovite material is thinner, flexible, and cheaper.
According to reports, they designed a new, power generation equipment consisting of two series of whole calcium titanium mine solar cells, which can convert the sunlight into electric energy at a comprehensive efficiency of 20.3%, and the photoelectric conversion efficiency is close to the market. Silicon-based solar cell.
The researchers say that the calcium titanium solar cell series equipment is low. The production of silicon-based solar panels first processed into single crystal silicon, process requires 1600 degrees Celsius high temperature, and manufacturing a perovskite solar cell, can process common material for tin, lead in the laboratory, then spray in glass at room temperature superior. The stability of the perovskite material has always been a problem.
Silicon-based solar panels mounted on the roofs can usually use 25 years or even longer, but some perovskite materials are rapidly degraded in humid or illuminating environments. Previous experiments show that the calcium titanium mine materials made of tin are particularly unstable. The researchers put them with the perovskite solar cell made of tin mixing multiple substances and the perovskite solar cell made of tin for 4 days in 100 degrees Celsius, and found the thermal stability and air stability of the former.
Very good, it is the latter never have. This research results were published in the new phase "Science" magazine. .
