CAS QIBEBT team improves graphdiyne (GD)-based solar cells

JIU Tonggang’s group from CAS Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) has developed a dual doping GD into electron transport layers of perovskite solar cells (PSCs), and reached a certified power conversion efficiency (PCE) of 20%. The employment of dual doping GD produced better film morphology of interface layers and electron transport efficiency occurring at PCBM and ZnO layers attributed to strong π-π stacking interaction between GD particles and PCBM/ZnO films. Graphdiyne (GD), an advanced full carbon nano structured material, is regarded as the most stable synthetic allotrope of carbon family for its unique structural characteristics of rigid carbon network, highly π-conjugated structure, a natural band gap and uniformly distributed pores.
