OverviewEfficiencyApplicationsHistoryDeclining costs and exponential growthTheoryMaterialsResearch in solar cells

Solar cell efficiency may be broken down into reflectance efficiency, thermodynamic efficiency, charge carrier separation efficiency and conductive efficiency. The overall efficiency is the product of these individual metrics. The power conversion efficiency of a solar cell is a parameter which is defined by the fraction of incident power converted into electricity.

How do solar cells work?

A single solar cell (roughly the size of a compact disc) can generate about 3–4.5 watts; a typical solar module made from an array of about 40 cells (5 rows of 8 cells) could make about 100–300 watts; several solar panels, each made from about 3–4 modules, could therefore generate an absolute maximum of several kilowatts (probably just enough to meet a home''s
