Hybrid Solar Cells 效率10.9% 太陽能電池 雜化 發(fā)表在science上 已有20人參與

The energy cost associated with separating tightly-bound excitons, photo- generated electron-hole pairs, and extracting free charges from highly disordered low mobility networks represent fundamental losses for many low-cost photovoltaic technologies. We report a low-cost, solution-processable solar cell based on a highly crystalline perovskite absorber with intense visible-to-near-infrared absorptivity that has a power conversion efficiency of 10.9% in a single junction device under simulated full sunlight. This “meso-superstructured solar cell” (MSSC) exhibits exceptionally few fundamental energy losses illustrated by generating open-circuit photovoltages of over 1.1 volts, despite the relatively narrow absorber band gap of 1.55 electron volts. The functionality arises from the use of mesoporous alumina as an inert scaffold which structures the absorber and forces electrons to reside in and be transported through the perovskite.[ Last edited by tanhua815 on 2012-10-7 at 18:00 ] |
