It has a low coefficient of light absorption and can be used as the active layer, electron acceptor and interfacial layers in photovoltaic cells (Arnberg et al. 2012). Fig. 3
The photovoltaic cells based on 2D heterostructures have superior absorption coefficients, elevated radiative efficiency, and well-defined interfaces, resulting in the highest power-to-weight ratio of the active material.
The linear absorption of intrinsic, i.e., undoped, graphene for perpendicularly incident light equals 2.3%, a remarkably large value for a material just one atom thick. In addition, its third-order nonlinear-optical response—the
Organolead triiodide perovskite is an ideal material because of its large light absorption coefficient, 4 long carrier lifetime, 5 and low cost. 6, 7 Up to now, the hybrid perovskite has
The proposed broadband graphene-based solar absorber is analyzed in terms of absorption characteristic with 82.7% absorption in the infrared region (280–380 THz), 86.5% absorption in
The exact value of the coefficient of graphene/polymer composite may vary due to the flake thickness and size distribution, as Su et al. report in their study on RGO (reduced
Solar energy is a reliable and abundant resource, and solar cells are an efficient and useful way to capture it. The sun delivers 1367 W/m 2 of solar energy into the atmosphere
Inorganic crystalline silicon solar cells account for more than 90% of the market despite a recent surge in research efforts to develop new architectures and materials such as organics and perovskites. The reason
In these 2D/3D heterojunction-based emerging photovoltaic cells, a light energy to electricity conversion efficiency of 15–17% can be achieved with improved nanoarchitectures and combined
The results showed that the doped graphene samples absorb most light in the visible range between 476 and 568 nm in the presence of BPB, and the band gap values obtained using Tauc''s formalism
Graphene is an ideal ultrathin material for various optoelectronic devices, but poor light–graphene interaction limits its further applications particularly in the visible (Vis) to
The conversion of light into electricity is known as the photovoltaic effect, and the first solid state organo-metal halide perovskite solar cell that utilised this effect were invented
