Photovoltaic cells degradation is the progressive deterioration of its physical characteristics, which is reflected in an output power decrease over the years. Consequently, the photovoltaic module continues to convert solar energy into electrical energy although with reduced efficiency ceasing to operate in its optimum conditions.
A solar cell, also known as a photovoltaic cell, is an electrical device that transforms light energy directly into electrical energy using the photovoltaic effect.
The functioning of photovoltaic cells is based on the photovoltaic effect. When the sunlight hits semiconductor materials such as silicon, the photons (light particles) impact the electrons of these materials, releasing them and generating an electric current.
The solar photovoltaic (PV) is the device which does the actual work of conversion of the solar energy to electrical energy, offering benefits of being clean energy with rigorous development history, constantly declining manufacturing cost and continuously improving efficiency .
This versatility allows photovoltaic cells to be used both in small-scale systems and large-scale projects, expanding the generation sources and complementing the energy mix in different contexts. What is a photovoltaic cell?
