Herein, the latest progresses of polymer solar cells with efficiency over 17% are briefly reviewed from the aspects of active material design, interface material development, and device technology. At last, the opportunities and challenges of organic photovoltaic commercialization in the future are discussed.
The high dipole moments exert an FEP effect and align perovskite energy level. 23.43 % efficiency is achieved with excellent stability. Regulation of interface defects and the extraction or transport of charge carriers are essential to enhance the stability and photovoltaic performance of perovskite solar cells (PSCs).
Regulation of interface defects and the extraction or transport of charge carriers are essential to enhance the stability and photovoltaic performance of perovskite solar cells (PSCs). A multifunctional intermediate layer of 2,7-dibromobenzo [1,2-b:6,5-b'] dithiophene-4,5-dione (DBO) is incorporated into PSCs.
Among PSCs, flexible perovskite solar cells (FPSCs) are lightweight and bendable, making them easier to transport and install than rigid PSCs, and hence can be used in wearable and portable electronics, space energy systems, multifunctional integrated buildings, unmanned systems, and other applications.
PSCs have attracted great interests because of their high efficiency and easy processing over large areas. Compared with other flexible solar cells, FPSCs have the advantages of high efficiency, low cost, and simple fabrication process, etc.
Constructing ternary structure is one of the most effective design strategies to break the efficiency ceiling of traditional binary organic solar cells (OSCs). Here, a new Y-series non-fullerene acceptor (Y-T) featuring 1,3-diethyl-2-thiobarbituric acid (DTBA) end groups is developed as a third component for the classical PM6:Y6 binary system.
