All-polymer solar cells (all-PSCs) are considered a promising category of organic solar cells (OSCs) for industrialization due to their enhanced stability, mechanical durability and film-formation property. Most of the high efficiencies in the all-PSCs field are achieved by using chloroform (CF) as the processing solvent. However, it is a highly volatile solvent and the resultant film condition depends strongly on the processing condition.

Assistant Prof. Zhang Guangye from College of New Materials and New Energies at Shenzhen Technology University (SZTU) and his team members investigated the use of sequential processing (SqP) for active layer preparation and reported 18.1% efficient all-PSC devices, the highest efficiency of all-PSCs prepared using non-halogen solvents. The work was published in Advanced Energy Materials (IF: 27.8) and titled “18.1% Ternary All-Polymer Solar Cells Sequentially Processed from Hydrocarbon Solvent with Enhanced Stability”. Assistant Prof. Zhang Guangye, Distinguished Prof. Li Shunpu and Associate Prof. Qiu Mingxia from College of New Materials and New Energies are the corresponding authors, postgraduate student Zhao Chaoyue the first author and SZTU is the first affiliation.
