Polymer solar cells have been receiving attention because of their light weight, mechanical flexibility, low costs and roll‐to‐roll manufacturing properties. Based on the advantage of harvesting more photons, lots of low band‐gap polymer donors have been used to fabricate organic solar cells (OSCs) to achieve high efficiency. The power conversion efficiency (PCE) of polymer OSCs has been continuously increasing in the past ten years and a PCE >12% has been reported in 2017. To further improve the PCE of OSCs, much effort has been focused on developing new photoactive materials and efficient processes. Here, Yang et al. (article No. 201700178 ) the current advances in all‐solution processed polymer solar cells are described. The PCE was improved by 7.8% by using HAT‐CN to replace the traditional hole transport layer (PEDOT:PSS). This work provides a simple and an efficient approach for preparing all‐solution processed polymer solar cells.
