Perovskite Solar Cell Efficiency Breakthough

The researchers said that in the 16 square centimeter of large perovskite solar cells, and now has been able to achieve a conversion efficiency of 12.1% level, which is the largest size of a single perovskite solar cells can achieve the highest efficiency; the results And has been the United States Newport Corp. International Testing Center of the test certification. The new battery is at least 10 times more powerful than at least one of the highest performance perovskite solar cells ever certified.
The team also achieved an efficiency rating of 18 percent on a single 1.2-square-meter perovskite battery and 11.5 percent efficiency on a 16-square-meter 4-cell perovskite micromodule Grade, thereby achieving greater grain formation.
"This is a very popular field of research, and many research teams are competing to enhance their solar cell design." Australian Advanced Solar Technology Center (ACAP) senior researcher Anita Ho-Baillie said: "Perovskite since 2009, Of the efficiency level is only 3.8%, but since then the technology began to develop rapidly, is expected in a year or so, we can achieve 24% efficiency level. "The researchers plan goal is to perovskite solar power generator cell efficiency To 26%.
Perovskite The use of mixed organic-inorganic lead or tin halide-based materials as the active layer for the collection of light is quite common because of its low production cost, ease of manufacture at low temperatures and even spraying onto the surface.
"The versatility of perovskite solution deposition allows it to be sprayed, printed or painted on solar cells," Ho-Baillie said. "The diversity of the chemical composition also helps to make the cell transparent, Or manufactured in different colors. "This research is part of the Solar Excellence Program of the Australian Renewable Energy Agency (ARENA).
