摘要： An inverted bulk heterojunction perovskite–PCBM solar cell with a high fill factor of 0.82 and a power conversion efficiency of up to 16.0% was fabricated by a low-temperature two-step solution process. The cells exhibit no significant photocurrent hysteresis and their high short-circuit current density, fill factor and efficiency are attributed to the advantageous properties of the active layer, such as its high conductivity and the improved mobility and diffusion length of charge carriers. In particular, PCBM plays a critical role in improving the quality of the light-absorbing layer by filling pinholes and vacancies between perovskite grains, resulting in a film with large grains and fewer grain boundaries. Bulk heterojunction perovskite solar cells with a high fill factor are reported. 其他題名： Nature Photon 出版者： London: Nature Publishing Group UK 出版日期： 2016-03-01 出處： Nature photonics, 2016-03, Vol.10 (3), p.196-200 資源來源： SpringerLink Journals 版權： Springer Nature Limited 2016 版權： Copyright Nature Publishing Group Mar 2016 識別號： ISSN: 1749-4885 識別號： EISSN: 1749-4893 識別號： DOI: 10.1038/nphoton.2016.3
