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.
To design efficient solar cells, different types of materials are used in geometrically engineered configurations, each having its pros and cons. Designing solar cells involves evaluating their efficiencies, bandwidth, tolerance to environmental conditions, and robustness to the incident angles of incoming waves [1, 2].
The basic principles of modern organic solar cells are summarized. Namely, issues on exciton, D/A sensitization, exciton diffusion, blended junction, route formation, \ (\pi - \pi\) stacking orientation, HOMO–LUMO gap tuning, non-radiative recombination, tandem cells, and doping are discussed.
There are two main approaches for developing solar cells: photovoltaic and photothermal technologies. Photovoltaic solar cells benefit from an active region whose performance can be improved by embedding nanoparticles with different shapes and materials.
The two primary solar cell design technologies are photovoltaic and photothermal systems. Their design key points are introduced in this chapter. The efficiency and the operating bandwidth are important factors for evaluating the performance of solar cells.
