Hui-Seon Kim,Chang-Ryul Lee,Jeong-Hyeok Im,Ki Beom Lee,Thomas Moehl,Arianna Marchioro,Soo-Jin Moon,Robin Humphry-Baker,Jun-Ho Yum,Jacques-E. Moser,Michael Grätzel,Nam-Gyu Park +11 more
TL;DR: The use of a solid hole conductor dramatically improved the device stability compared to (CH3NH3)PbI3 -sensitized liquid junction cells.
Journal ArticleDOI
6.5% efficient perovskite quantum-dot-sensitized solar cell
TL;DR: Perovskite QD-sensitized 3.6 μm-thick TiO(2) film shows maximum external quantum efficiency (EQE) of 78.6% at 530 nm and solar-to-electrical conversion efficiency of 6.54% at AM 1.5G 1 sun intensity (100 mW cm(-2)), which is by far the highest efficiency among the reported inorganic quantum dot sensitizers.
Journal ArticleDOI

TL;DR: It is shown that a pair of perovskite cells connected in series can power the electrochemical breakdown of water into hydrogen and oxygen efficiently, and the combination of the two yields a water-splitting photocurrent density and a solar-to-hydrogen efficiency of 12.3%.
Journal ArticleDOI
Growth of CH3NH3PbI3 cuboids with controlled size for high-efficiency perovskite solar cells.
TL;DR: In this article, a two-step spin-coating procedure was used to control the size of the cuboid cuboid of CH(3)NH(3)-PbI(3), achieving an average efficiency exceeding 16% and best efficiency of 17%.
Journal ArticleDOI
11% Efficient Perovskite Solar Cell Based on ZnO Nanorods: An Effective Charge Collection System
TL;DR: In this paper, a perovskite solar cell based on ZnO nanorods was prepared, and its photovoltaic performance was investigated, and the results showed that CH3NH3PbI3 infiltrated ZnOs showed a power conversion efficiency of 11.13% with short-circuit current density Jsc of 20.03 mA/cm2 calculated from external quantum efficiency (EQE) data.
