Thin-film solar efficiencies rose to 10% for Cu 2 S/CdS in 1980, and in 1986 ARCO Solar launched the first commercially-available thin-film solar cell, the G-4000, made from amorphous silicon.
Chen and Mickelsen were the first to illustrate thin-film CuInSe2/CdS solar cells in 1981. Variation in selenide layer evaporation increases effectiveness. While the rates of In and Se deposition remained constant, the rate of Cu deposition was adjusted to achieve the desired composition and resistivity.
Thin film solar cells are favorable because of their minimum material usage and rising efficiencies. The three major thin film solar cell technologies include amorphous silicon (α-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe).
Kazmerski et al. , in 1976, created the first thin film CIGS solar cell having a conversion efficiency of 4.5%. The structure of the CIGS is given in Fig. 7, with soda lime glass as the substrate. On top of the glass is the molybdenum, which contacts the p-type Cu (InGa)Se 2.
After Willoughby Smith discovered the photoconductivity of selenium (Se) in 1873, Charles Fritts constructed the first solid-state solar cells in 1883 by sandwiching Se film between a metal foil and a thin gold (Au) layer (1).
The three most widely commercialized thin film solar cell technologies are CIGS, a-Si, and CdTe. The straight bandgap (Table 1) is a property shared by all three of these materials, and it is this property that allows for the use of extremely thin materials .
Photovoltaic Technology: The Case for Thin-Film Solar Cells
Hydrogenated amorphous silicon was introduced as a material with a potential for semiconductor devices in the mid-1970s and is the first thin-film solar cell material that has reached the stage of large-scale production (∼20 MW p /year at present). Amorphous silicon has, in the visible range of the spectrum, a higher optical absorption ...

What are thin-film solar cells? Types and description
Thin-film solar cells are the second generation of solar cells. These cells are built by depositing one or more thin layers or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic, or metal. The thickness of the film varies from a few nanometers (nm) to tens of micrometers (µm). The film is much thinner than the first-generation conventional …
