The researchers foresee in the production of crystal to solve the problems on the industrial manufacturing

Last week in "Science" magazine, scientists from La Sia Alamos National Laboratory reveals a new technology, the technology-based thermal solution casting method, you can use the large size of the perovskite crystals Health efficient solar cell can be mass-produced length.

"These perovskite crystal may provide a promising route for developing low-cost, clean energy based on solar energy solutions, to provide energy for the future."   Leading scientists Aditya Mohite purpose of this item says Road.

The latest manufacturing process for solar photovoltaic panels uses high-purity, large-size, wafer-size single-crystal semiconductors that are manufactured from a highly-skilled, high-temperature crystal growth process that is viewed as the future of efficient solar technology. Solar cells consist of organic - inorganic perovskites, which can provide near-silicon efficiency, but perovskite materials still have some limitations that limit their diversification into commercial applications. This has long been criticized. The Las Alamos laboratory successfully compensated for this shortcoming.

The researchers used a perovskite material containing large crystal particles to produce planar solar cells and achieved a photoelectric conversion efficiency of 18% , which is the highest efficiency reported in perovskite-based light energy conversion devices. These batteries proved the variability of the small batteries, and the solar cells manufactured therefrom did not exhibit photo-electrical hysteresis. The photo-electrical hysteresis reaction is the bottleneck that limits the stable operation of perovskite devices.

"Characterization and simulation can improve performance and reduce large size defects and improve the charge-carrying mobility of large-grain perovskite materials."   Aditya Mohite said, "We have proven the quality of these perovskite crystals and observed a high quality silicon and gallium arsenide semiconductors at the same level."

The researchers predict that their crystal growth technology will lead the field towards the development of wafer-size perovskite crystals for the manufacture of high-efficiency solar cells, as well as for other polydispersities, defects, and crystals that are manufactured by solution. It is necessary for the industry to reorganize the limited material films.
