Hua University of Science and Technology develops perovskite solar cells with a conversion efficiency of 15%

Recently, Chen Wei, associate professor of the National Laboratory of Optoelectronics of Huazhong University of Science and Technology, independently developed large-area perovskite solar cells, passed the certification of the Photovoltaic Technology Research Center of the Japan Institute of Advanced Industrial Technology (AIST), and its conversion efficiency reached 15%, the highest level in the world
.

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.
The results were first written into the authoritative solar cell efficiency record compiled by Martin Green, the "father of solar cells
".

Perovskite solar cells are a new type of photovoltaic technology that has emerged in recent years, and its efficiency record has improved rapidly
.
Perovskite materials have the characteristics of
abundant raw materials, low cost, superior photoelectric properties, solution processing, and low temperature preparation.
However, perovskite solar cells generally have stability problems, and many batteries decay during testing
.
In addition, perovskite solar cells also have widespread hysteresis
