A solar cell is basically a p-n junction diode. Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics – such as current, voltage, or resistance – vary when exposed to light. Individual solar cells can be combined to form modules commonly known as solar panels.
The diagram illustrates the conversion of sunlight into electricity via semiconductors, highlighting the key elements: layers of silicon, metal contacts, anti-reflective coating, and the electric field created by the junction between n-type and p-type silicon. The solar cell diagram showcases the working mechanism of a photovoltaic (PV) cell.
A solar cell functions similarly to a junction diode, but its construction differs slightly from typical p-n junction diodes. A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor. We then apply a few finer electrodes on the top of the p-type semiconductor layer.
Conceptually, the operating principle of a solar cell can be summarized as follows. Sunlight is absorbed in a material in which electrons can have two energy levels, one low and one high. When light is absorbed, electrons transit from the low-energy level to the high-energy level.
The construction of Solar cells includes the following layers Silicon Layers and Solar Cells Solar panels are constructed of solar cells, which transform the sun's energy into electricity, allowing them to generate electricity from UV lighting even when it is gloomy outside.
The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 to 0.6 volts. By itself this isn’t much – but remember these solar cells are tiny. When combined into a large solar panel, considerable amounts of renewable energy can be generated.
