In this article we present a very simple model of a solar cell. Many notions presented in this chapter will be new but nonetheless the great lines of how a solar cell works should be clear. All the aspects presented in this chapter will be discussed in larger detail in the following chapters. The working …
Introduction Several paths exist toward the realization of photovoltaic devices with efficiency greater than 50%, including multiple junction solar cells (tandems), solar cells using optical frequency shifting (such as up/down conversion or thermophotonics), multiple exciton generation (MEG) from a single photon, multiple energy level solar cells (such as intermediate band solar cells), and hot carrier …
Photovoltaic (PV) generations The first generation of PV cells was discovered at Bell Telephone in 1954, when scientists discovered that silicon (is one of element found in sand) created an electric charge when exposed to sunlight. Traditional solar cells are made from silicon, one of the most common elements on Earth. Second-generation of PV cells …
