Journal ArticleDOI
Long-Range Balanced Electron- and Hole-Transport Lengths in Organic-Inorganic CH3NH3PbI3
Guichuan Xing,Nripan Mathews,Shuangyong Sun,Swee Sien Lim,Yeng Ming Lam,Michael Grätzel,Michael Grätzel,Subodh Mhaisalkar,Tze Chien Sum +8 more
TL;DR: Two studies show, using a variety of time-resolved absorption and emission spectroscopic techniques, that perovskite materials manifest relatively long diffusion paths for charge carriers energized by light absorption, highlighting effective carrier diffusion as a fruitful parameter for further optimization.
Journal ArticleDOI
The origin of high efficiency in low-temperature solution-processable bilayer organometal halide hybrid solar cells
Shuangyong Sun,Teddy Salim,Nripan Mathews,Martial Duchamp,Chris Boothroyd,Guichuan Xing,Tze Chien Sum,Yeng Ming Lam,Yeng Ming Lam +8 more
TL;DR: In this paper, the authors reported the origin of the high efficiency in solution-processable bilayer solar cells based on methylammonium lead iodide (CH3NH3PbI3) and [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM).
Journal ArticleDOI
Organic photovoltaic devices using highly flexible reduced graphene oxide films as transparent electrodes.
Zongyou Yin,Shuangyong Sun,Teddy Salim,Shixin Wu,Xiao Huang,Qiyuan He,Yeng Ming Lam,Hua Zhang +7 more
TL;DR: This work demonstrates the highly flexible property of rGO films, which provide the potential applications in flexible optoelectronics, and fabrication of flexible organic photovoltaic devices.
Journal ArticleDOI
Perovskite-based solar cells: impact of morphology and device architecture on device performance
TL;DR: In this paper, a comparison of the material selection for various layers as well as their corresponding impact on the perovskite film and device behavior in both device architectures is presented.
Journal ArticleDOI
Charge Accumulation and Hysteresis in Perovskite-Based Solar Cells: An Electro-Optical Analysis
TL;DR: In this paper, a detailed electro-optical study is presented that indicates the hysteresis originates from lingering processes persisting from sub-second to tens of seconds, possibly involving methylammonium ions rotation/displacement and lattice distortion.
