PHOTO-VOLTAGE-BATTERY (SOLARSEL) SCHEMATIC CIRCUIT DIAGRAM

The “PHOTO-VOLTAGE-BATTERY” is an electronic device that harnesses the photovoltaic effect, a remarkable physical and chemical phenomenon, to directly convert light energy into electricity. This device is commonly referred to as a solar cell or photovoltaic cell. It belongs to the category of photoelectric cells, which are characterized by their capacity to alter electrical attributes like current, voltage, or resistance in response to exposure to light. Solar cells, at an individual level, often serve as the foundational components of photovoltaic modules, colloquially known as solar panels. Typically, a standard single-junction silicon solar cell can generate a maximum open-circuit voltage ranging from approximately 0.5 volts to 0.6 volts.

However, I can provide some general information based on common terminology:

Photovoltaic (PV) Cells:

  • PV cells, commonly known as solar cells, are devices that convert sunlight directly into electricity. When sunlight hits the PV cell, it generates a flow of electricity through a semiconductor material.

Solar Battery:

  • A solar battery, or solar storage system, is a device used to store excess electricity generated by solar panels during the day for later use, such as during the night or on cloudy days. These batteries are typically rechargeable and help increase the self-consumption of solar energy in residential and commercial settings.

Photovoltaic Battery:

  • This term could potentially refer to a battery system integrated with a photovoltaic solar array, where the electricity generated by the solar panels is stored in the battery for later use. Such systems are commonly used to improve energy efficiency and provide backup power in case of grid outages.

It is known as a solar cell. A DC generator that converts the light energy falling on it into electrical energy. It is a PN semiconductor composition placed on a metal base. On top is a metal ring. The cell is placed in a window housing with the connection terminals out.

Nowadays, many studies are carried out. It is
used in light-working calculators. Since it is still an expensive technology, its use in homes and workplaces has not
become widespread. In the near future, the use of electrical energy from solar energy will be increased by placing solar panels in the light parts of the buildings. Usually expressed by the following symbols

When light reaches the surface of a photovoltaic cell, specifically the photovoltaic (P) layer, it penetrates through the transparent glass window, initiating the movement of electrons within the PN junction region. This movement is a consequence of the interplay between negatively charged electrons and positively charged holes. Electrons are transferred to the N layer, while holes accumulate in the P layer. Consequently, the external connection terminal linked to the N-layer serves as the negative pole of a DC generator, while the positive external connection terminal is associated with the P-layer. As the intensity of light increases, additional electron-hole pairs are generated, subsequently elevating the generator’s potential.

It’s worth noting that the maximum voltage attainable is not solely contingent on light intensity but also influenced by the cell’s dimensions. In simpler terms, merely augmenting the light intensity incident on a photovoltaic cell won’t guarantee a desired increase in voltage. To achieve this, photovoltaic cells can be connected in series to boost current or linked in parallel to enhance voltage, depending on the specific requirements.
