Polymer Solar Cell Polymer solar cells (PSCs) and dye-sensitized solar cells (DSSCs) are the most studied photovoltaic devices in recent years. A polymer solar cell is a sort of flexible PV solar cell prepared with polymers, large molecules of persistent structural units, that generates an electric current from sunlight by the photovoltaic effect.

Even the DNA in your cells is a polymer. By definition, polymers are large molecules made by bonding (chemically linking) a series of building blocks. The word polymer comes from the Greek words for "many parts.". Each of those parts is scientists call a monomer (which in Greek means "one part").
