The strategic amalgamation of other semiconductor substances like GaAs (Gallium Arsenide) onto the Ge base culminates in multiple junctions that synergistically elevate the overall efficacy of solar cells. Contrasting silicon-based brethren, germanium solar cells showcase reduced recombination frequencies courtesy of superior conductive traits.
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.
Nonetheless, monetary considerations retain paramount importance while transitioning from laboratory-scale fabrication towards commercialization. In the realm of high-efficiency solar power systems, a profound enigma lies in the utilization of germanium as a semiconductor material.
The realm of solar cells has recognized germanium substrates as potent absorber material, exhibiting high efficiency. A typical thickness of 500 nanometers in the said substrates is known to significantly amplify the photocurrent generated by a single junction solar cell.
The base layer or substrate of these cells often boasts germanium content due to its ability to offer a steadfast platform for ensuing layers – an element that significantly impacts the system’s overall efficacy. Of late, there’s been an observable surge of interest revolving around multi-junction solar cells leveraging germanium substrates.
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.
Fabrication of Solar Cell
The screen printing of solar cells has a significant disadvantage of shading due to the metallic contact on the n-type layer. This layer prevents the solar cell from being fully exposed to the sunlight, which means a lesser effective area on the solar cell surface. Therefore, the burial of metallic contact within a groove in the solar cell is ...

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 [].
