Recently, large-area perovskite solar cells independently developed by Chen Wei, associate professor of the National Laboratory of Optoelectronics of Huazhong University of Science and Technology, passed the certification of the Photovoltaic Technology Research Center of the Japan Institute of Advanced Industrial Science and Technology (AIST), filling the gap
in the solar cell efficiency record table.
It is understood that AIST is one of
the most authoritative solar cell certification bodies in the world.
The large-area perovskite battery sent by Chen Wei was successfully certified as the highest efficiency of 15%
in the world.
Perovskite solar cells are a new type of photovoltaic technology that has emerged in recent years, and its efficiency record has improved rapidly
.
However, perovskite solar cells generally have stability problems, and many batteries decay during testing
.
In addition, perovskite solar cells also have widespread hysteresis
.
Chen Wei and his team tested tens of thousands of battery current/voltage output characteristic (IV) curves, and after comparing several of the most common perovskite solar cell structures, they found that "P-i-N" trans-planar structure cells are easier to eliminate hysteresis
.
Chen Wei said that by further improving the perovskite film quality and composition, the efficiency record of large-area perovskite solar cells is expected to advance to the level
of 20%.
