1. What physical phenomenon is responsible for the direct conversion of solar energy into electrical energy in a photovoltaic cell?
The photovoltaic effect The Joule effect The thermoelectric effect The Hall Effect
2. Which of the following factors does not directly influence the solar radiation received by an Earth surface?
The latitude of the site The inclination of the surface Cloud cover The frequency of the electrical grid
3. In a silicon photovoltaic cell, what is the main role of the PN junction?
Store the energy produced Increase the temperature of the cells Create an electric field that allows for charge separation Convert direct current to alternating current
4. When several photovoltaic cells are connected in series, which electrical parameter increases primarily?
Intensity only Tension Storage capacity Frequency
5. Which scientist is recognized for having discovered the photovoltaic effect?
Edmond Becquerel Nikola Tesla James Watt Alessandro Volta
6. What characteristic constitutes the main advantage of polycrystalline silicon photovoltaic cells compared to monocrystalline cells?
Superior yield Better value for money A total absence of heat loss Production independent of sunlight
7. Which statement correctly describes the role of bypass diodes in a photovoltaic module?
They increase the module's nominal voltage. They temporarily store the energy produced. They convert direct current into alternating current. They limit losses and protect cells in case of partial shading.
8. Why does high temperature reduce the efficiency of a photovoltaic panel?
Because it reduces the electrical performance of photovoltaic cells. Because it increases the reflection of sunlight. Because it improves the mechanical resistance of the glass. Because it increases the frequency of the current produced.
9. Of the following technologies, which one generally offers the highest performance for common commercial applications?
Amorphous silicon Polycrystalline silicon Monocrystalline silicon Cadmium telluride (CdTe)
10. What is the main objective of a cooling system applied to photovoltaic panels?
Increase the panel's output voltage Limit the temperature rise in order to maintain efficiency and extend the lifespan of the modules Store the thermal energy produced Replace the storage batteries
