The working principle of a photovoltaic (PV) cell involves the conversion of sunlight into electricity through the photovoltaic effect. Here's how it works: Absorption of Sunlight: When sunlight (which consists of photons) strikes the surface of the PV cell, it penetrates into the semiconductor material (usually silicon) of the cell.
The equivalent circuit of a PV cell typically consists of the following components: Photovoltaic Current Source (Iph): This represents the current generated by the PV cell when exposed to light. It is proportional to the intensity of incident light and the efficiency of the cell.
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
Solar energy global distribution by belt and nation at variable geometrical regions on the globe is also presented. The rate at which solar energy reaches a unit area on the earth is defined as the “solar irradiance” or “insolation,” which are measured in the units of watts per square meter (W/m 2).
The characteristics of Photovoltaic (PV) cells can be understood in the terms of following terminologies: Efficiency: Determines the ability to convert sunlight into electricity, typically measured as a percentage. Open-Circuit Voltage (Voc): Maximum voltage produced when not connected to any external load.
What is needed to enable this potential is to reach a consensus over the outdoor test conditions (OTCs) that are representative of the atmospheric conditions of different regions of the world, so that the PV cell designs can be optimized based on their location of installation.
