In comparison, the working principle of this solar cell is quite different from perovskite solar cells and inorganic p–n junction solar cells. When OPVs are illuminated, a localised and strongly bound exciton (i.e. a bound electron–hole pair) is generated, with the electron in the LUMO (lowest unoccupied molecular orbital) and the …

layer for efficient perovskite solar cells: a first-principles study Le Huang1, Huafeng Dong2, Nengjie Huo3, Zhaoqiang Zheng1, Hui-Xiong Deng4, Gang Zhang5, Yuan Cheng5*and Jingbo Li1,3* ABSTRACT Recent years have seen swift increase in the power conversion efficiency of perovskite solar cells (PSCs).
Solar cells are made of semiconductor material, typically silicon in crystalline solar cells. Traditionally, a solar cell has two layers: an n-type with a high concentration of electrons and a p-type with a relatively low concentration of electrons. When sunlight hits the n-type layer, electrons flow from that section to the second and create an …
Solar Cell (multicrystalline silicon) ... Silicon crystals are laminated into n-type and p-type layers, stacked on top of each other. Light striking the crystals induces the "photovoltaic effect," which generates electricity. The electricity produced is called direct current (DC) and can be used immediately or stored in a battery. ...

Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
