Silicon solar cells are the most broadly utilized of all solar cell due to their high photo-conversion efficiency even as single junction photovoltaic devices. Besides, the high relative abundance of silicon drives their preference in the PV landscape.
Besides, the high relative abundance of silicon drives their preference in the PV landscape. Silicon has an indirect band gap of 1.12 eV, which permits the material to absorb photons in the visible/infrared region of light.
The word Photovoltaic is a combination of the Greek Work for light and the name of the physicist Allesandro Volta. It refers to the direct conversion of sunlight into electrical energy by means of solar cells. So very simply, a photovoltaic (PV) cell is a solar cell that produces usable electrical energy.
As one of the PV technologies with a long standing development history, the record efficiency of silicon solar cells at lab scale already exceeded 24% from about 20 years ago (Zhao et al., 1998).
means to decrease the cost of silicon solar cells is to reduce the amount of silicon used. This could be done by reducing the thickness of the solar cell. However, as the thickness of the solar cell is decreased more and more light penetrates the cell and is not exploited to create electron hole pairs.
The circuit allows the electrons to flow to the electron-poor back of the cell from the electron-rich front of the cell. Photovoltaic panels are oriented to maximize the use of the sun’s light, and the system angles can be changed for winter and summer. When a panel is perpendicular to the sunlight, it intercepts the most energy.

Introduction to Solar Cells
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 [].
