Understanding the Composition of a Solar Cell
Since the sun is generally the source of radiation, they are often called solar cells. Individual PV cells serve as the building blocks for modules, which in turn serve as the building blocks for arrays and complete PV systems (see Figure 1). Figure 1. The basic building blocks for PV systems include cells, modules, and arrays.
Photovoltaic device innovation for a solar future
140 years ago, inventor Charles Fritts made solar cells from selenium, hoping to offer an alternative to the coal-fired power plant that Thomas Edison built in New York City the year before. 1 The 1%–2% efficient devices, Au on Se, were installed on a roof top in 1884 but obviously gained limited traction. The first practical Si solar cell was …
