제목 The strategy for Green Solvent Processing and Application to Hole Transport Materials for Perovskite Solar Cells
초록 The concept of asymmetry in the monomer leads to irregularity despite being a homopolymer. Green processing was approached with asymmetric alkoxy substitution, resulted in high efficient HTMs. Using applicable green solvents from Hansen parameter fitting, we characterize asymmetric polymer and fabricate hole transport layers. 2-methyl anisole is the green solvent that is used in food additives, which is edible and no harmful in human body. High absolute solubility in green solvent was exhibited by asymmetric structure named asy-PBTBDT, which induces the irregularity. The perovskite HTM using asy-PBTBDT demonstrates high PCE with chlorobenzene and 2-methyl anisole which is eco-friendly solvent. As it has not only environmental friendly processibility but also sufficient photochemical and device stability, it is expected to be an industrial material.
