“…[14][15][16][17][18][19][20][21] However, the complex synthesis process of Spiro-OMeTAD leads to a significant increase of the total cost of PSCs, limiting its future largescale industrial applications. [22][23][24][25][26][27][28][29] Therefore, many researchers have endeavored to develop novel low-cost and highly efficient HTMs to replace Spiro-OMeTAD. [30][31][32][33] From the reported literature, it can be found that both the core units and peripheral donor units have significant effects on the photovoltaic performance of HTMs.…”

Considering the inadaptability of traditional anodic bonding to polymer materials, the flexible anodic bonding process is developed. The bonding characteristics of the dynamic intelligent electric fields with the low-temperature plasma surface treatment to polymer and ultrasonic-assisted preconnection before bonding are very suitable for the anodic bonding of polymer elastomer to aluminum (Al) sheet. A series of composite polyurethane elastomer cathode materials (CPECs) with good bonding properties are prepared and characterized. The highest ionic conductivity of CPECs can reach to 2.7 Â 10 À3 S/cm (CPEC2) at 75 C. After bonded, it is determined that a uniform and dense intermediate bonding layer showed by SEM is formed between CPECs and Al. In addition, different elements including C, O, F, S, and Al are clearly iden-

As the key properties of perovskite solar cells (PSCs), the hole extraction and transport capabilities of the hole transport material (HTM) affect the photovoltaic performance of PSCs to a considerable extent, while both capabilities can be adjusted by molecular planarity. Therefore, in this work, the molecular planarity of the HTM is systematically optimized to regulate the hole extraction and transport capabilities. Along with the improvement in planarity, the HTM′s HOMO level is increased, leading to the enhancement of hole extraction capability. Meanwhile, the hole transport capability can also be improved due to the intensification of molecular stacking during the film formation. As a result, the planar HTM achieves a relatively high efficiency of 18.48 %, which is higher than that of spiro‐OMeTAD. Accordingly, the molecular planarity presents an important impact on the photovoltaic performance of PSCs, providing us with a promising strategy for further optimization of efficient HTMs.
