Advances in Modelling and Simulation of Halide Perovskites for Solar Cell Applications
Chol-Jun Yu
Perovskite solar cells (PSCs) are attracting great attention as the most promising candidate for the next generation solar cells. This is due to their low cost and high power conve…
Two-dimensional hybrid composites of SnS2 with graphene and graphene oxide for improving sodium storage: A first-principles study
Kum-Chol Ri, Chol-Jun Yu, Jin-Song Kim +1
Among the recent achievements of sodium-ion battery (SIB) electrode materials, hybridization of two-dimentional (2D) materials is one of the most interesting appointments. In this…
Structural and optoelectronic properties of the inorganic perovskites AGeX3 (A = Cs, Rb; X = I, Br, Cl) for solar cell application
Un-Gi Jonga, Chol-Jun Yu, Yun-Hyok Kye +3
We predict the structural, electronic and optic properties of the inorganic Ge-based halide perovskites AGeX3 (A = Cs, Rb; X = I, Br, Cl) by using first-principles method. In parti…
First-principles study on the chemical decomposition of inorganic perovskites \ce{CsPbI3} and \ce{RbPbI3} at finite temperature and pressure
Un-Gi Jong, Chol-Jun Yu, Yun-Hyok Kye +3
Inorganic halide perovskite \ce{Cs(Rb)PbI3} has attracted significant research interest in the application of light-absorbing material of perovskite solar cells (PSCs). Although th…
The maximum interbubble distance in relation to the radius of spherical stable nanobubble in liquid water: A molecular dynamics study
Song-Nam Hong, Song-Hyok Choe, Un-Gi Jong +2
The mechanism of superstability of nanobubbles in liquid confirmed by many experimental studies is still in debate since the classical diffusion predicts their lifetime on the orde…
Formation and characterization of ceramic coating from alumino silicate mineral powders in the matrix of cement composite on the concrete wall
Chol-Jun Yu, Byong-Hyok Ri, Chung-Hyok Kim +4
Enhancement of thermal performance of concrete wall is nowadays of great importance in reducing the operational energy demand of buildings. We developed a new kind of inorganic coa…
