Random copolymerization strategy for non-halogenated solvent-processed all-polymer solar cells with a high efficiency of over 17%

Abstract

With the innovation of new materials, the power conversion efficiencies (PCEs) of all-polymer solar cells (all-PSCs) have been boosted to over 17%. However, most of them are processed with toxic...

Development of rigidity-controlled terpolymer donors for high-performance and mechanically robust organic solar cells

“…While the mechanical properties of blend lms are affected by the mechanical properties of each component (i.e., P D and S A ), the morphological properties, which depend on the thermodynamic miscibility between P D and S A , also play an important role to determine both the electrical and mechanical properties of the blends. 11,[23][24][25][26][27][28][29][30][31] Thus, for achieving highly efficient and mechanically robust OSCs, it is important to design terpolymer donors containing appropriate bulky electro-active third components by considering their impact on the mechanical properties of the polymers as well as their blend morphology with S A s.…”

Simple Solvent Treatment Enabled Improved PEDOT:PSS Performance toward Highly Efficient Binary Organic Solar Cells

“…On the other hand, the solar cell based on PM6:BTP-2F-ThCl can achieve an efficiency of 17.70%, also outperforming the counterparts. At last, a 17.14% PCE is gained here due to the better HTM layer, which is one of the best values for non-halogenated solvent-treated binary all-polymer solar cells. − …”

Unveiling the Morphological and Physical Mechanism of Burn‐in Loss Alleviation by Ternary Matrix Toward Stable and Efficient All‐Polymer Solar Cells

“…[ 6–10 ] To date, the rapid development of pushing the efficiency of all‐PSCs over 17% demonstrates new vitality in this research field. [ 11–16 ]…”

“…[6][7][8][9][10] To date, the rapid development of pushing the efficiency of all-PSCs over 17% demonstrates new vitality in this research field. [11][12][13][14][15][16] Current research mainstream of all-PSCs is to further promote the PCEs as high as those of small molecule-composed counterparts, [17][18][19][20][21] and empirically the ternary blend strategy is one of the most commonly used methods to achieve this goal. [22][23][24][25][26][27][28] Notably, these works also prefer to claim enhanced device stability and sometimes better mechanical durability, but very few works provide an in-depth understanding of such improvements.…”
