It was recently learned that the team of Professor Liu Shengzhong and Dr.
Yang Dong of Shaanxi Normal University used solid ionic liquids as electron transport materials to prepare flexible perovskite solar cells with an efficiency of 16.
09%, breaking through the world's highest efficiency of previous flexible perovskite solar cells; The results were published in the journal Advanced Materials
.
"At present, a large number of silicon solar cells on the market cannot be prepared into flexible devices, and the price is high and difficult to apply
on a large scale.
" Yang Dong introduced
.
The perovskite material recently developed by Liu Shengzhong's team has a large light absorption coefficient, and can absorb and utilize sunlight well by preparing extremely thin
films.
In addition, the mechanical properties of perovskite films are very superior, so they can be used to prepare high-efficiency flexible solar cells
.
With no previous relevant work experience, Liu's team had to start from scratch, spending a lot of time looking for suitable materials that could be processed at low temperatures, from theoretical analysis to feasibility testing in experiments
.
Yang Dong said: "Perovskite solar cells are not only efficient, but also can be prepared into flexible devices
.
In the near future, car glass, roofs, people's backpacks, clothes, ships, satellites, etc.
, can be prepared into flexible solar cells
.
Green energy will be everywhere!"
