Nonetheless, very low thicknesses suffice to absorb most of the light in silicon solar cells. The typical thickness of a silicon solar cell is around 160 μm (only five times the thickness of a human hair!).
Using the provided quantum efficiency (QE), calculate the spectral response (SR) of a silicon solar cell. Plot the QE and SR as a function of wavelength. Estimate the photocurrent density generated by a silicon solar cell illuminated by the reference spectrum AM1.5G.
Light shining the solar cell will produce both a voltage and a current to generate electric power . A typical schematic diagram of silicon solar cell is shown in Fig. 1. PV energy conversion in solar cells consists of two essential steps. First, a material in which the absorption of light generates an electron-hole pair is required.
Conceptually, the operating principle of a solar cell can be summarized as follows. Sunlight is absorbed in a material in which electrons can have two energy levels, one low and one high. When light is absorbed, electrons transit from the low-energy level to the high-energy level.
Material Characteristics: Essential materials for solar cells must have a band gap close to 1.5 ev, high optical absorption, and electrical conductivity, with silicon being the most commonly used.
It has therefore no direct dependency on the cell’s area. In a good solar cell, the maximum voltage will be in the range of 0.6 to 0.8 times the value of the bandgap (divided by the charge q). For example, in the case of silicon, the best-performing solar cells produce a voltage of around 0.74 V.

Band diagram of a silicon solar cell, corresponding to very low current (horizontal Fermi level), very low voltage (metal valence bands at same height), and therefore very low illumination. When a photon is absorbed, its energy is given to an electron in the crystal lattice. Usually this electron is in the valence band.

Solar Cell (Photovoltaic system) Solar energy is directly converted into electrical energy using devices known as "photovoltaic cells or solar cells." Photovoltaic cells are fabricated from semiconducting materials like silicon as they produce electricity when light strikes their surface (the process of absorption).
