Chapter 4. The working principle of all today solar cells is essentially the same. It is based on the photovoltaic effect. In general, the photovoltaic effect means the generation of a potential difference at the junction of two different materials in response to visible or other radiation. The basic processes behind the photovoltaic effect are:
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.
This process is called diffusion and the resulting carrier flow diffusion current. As we did earlier for the case of a photocurrent in a solar cell, it will be more convenient to talk about current densities (expressed in A/cm2) to make the discussion independent of the semiconductor area.
Values for silicon, the most used semiconductor material for solar cells, are given in the appendix. Since raising the temperature will increase the thermal velocity of the carriers, diffusion occurs faster at higher temperatures. A single particle in a box will eventually be found at any random location in the box.
This chapter deals with the fundamentals of solar cells. A solar cell is a key device that converts light energy into electrical energy in a photovoltaic energy conversion. In most cases, semiconductor is used for solar cell material.
Diffusion is the random scattering of carriers to produce a uniform distribution. p> The rate at which diffusion occurs depends on the velocity at which carriers move and on the distance between scattering events. It is termed diffusivity and is measured in cm 2 s -1.
