What are the characteristics of all polymer solar cells

1. All-polymer solar cells (all-PSCs) have made similar progress in binary mixtures of electron-accepting polymers and donor polymers, but the best single-cell battery has only 8-10% PCEs. Lower than polymer solar cells based on small molecule NFAs. 2. The important challenge to improve the performance of all-PSCs is how to add short-circuit current (Jsc) and fill factor (FF) at the same time, because both of them are heavily dependent on the mixed form, although the lithium-ion battery forum has now successfully explored some controls And methods to optimize the morphology of the active layer blend of all-PSCs, but these methods also use solution-processed additives to achieve the best blend morphology and high-efficiency devices. 3. All polymer solar cells have synthesized a series of new n-type semiconductor random copolymers BSSx (xu003d10,20,50). Among them, each component is studied in detail with BSS0 as a reference control group. Ion battery manufacturers can produce all-PSCs with high efficiency (u003e9.6%) in each blend of BSSx and donor polymer PBDB-T without using solution processing additives. Among them, all-PSCs of BSS10:PBDB-T have high efficiency (u003e10%), nearly 100% internal quantum efficiency and small optical band gap energy loss (u003c0.6eV). In addition, all-PSCs produced by BSS10 and BSS20 have high external quantum efficiency (u003e85%) and small Eloss (u003c0.6eV). This study shows that the design and synthesis of random copolymer structures is a promising strategy for optimizing the morphology and improving the performance of all-polymer solar cell PSCs.
