All the aspects presented in this chapter will be discussed in greater detail in the following chapters. The working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag-netic radiation.
Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
This is the case for solar cells, in which electrons need to be able to exit the n side of the cell and holes need to be able to exit the p side (this will be thoroughly analyzed in Section 3.4). If the flow of the majority carriers is also blocked by the passivation layer, the solar cell cannot generate any photocurrent.
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.
They use semiconductors as light absorbers. When the sunlight is absorbed, the energy of some electrons in the semiconductor increases. A combination of p-doped and n-doped semiconductors is typically used to drive these high-energy electrons out of the solar cell, where they can deliver electrical work before reentering the cell with less energy.
In a solar cell, the electrical current produced by the absorption of light is called the photocurrent. The quantum efficiency (QE) of a solar cell is defined as the number of electrons that contribute to the photocurrent divided by the number of photons with a given energy or wavelength that impinge on the solar cell.
