Glossary Photovoltaics
Cadmium Telluride (CdTe) Solar Cell:
A thin-film solar cell technology that uses cadmium telluride as the semiconductor material, known for its low production costs.
Copper Indium Gallium Selenide (CIGS) Solar Cell:
Another type of thin-film solar cell that uses a combination of copper, indium, gallium, and selenium as the semiconductor material, offering a good balance between efficiency and cost.
HJT (Heterojunction Technology):
HJT is a solar cell technology that uses different layers of material with different band gaps to increase efficiency. This technology combines amorphous silicon with crystalline silicon to achieve higher efficiency.
IBC (Interdigitated Back Contact):
IBC is an advanced solar cell technology in which the electrical contacts are located on the back side of the cell to minimize front side loss and maximize efficiency.
Inverter:
A device that converts the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which is used in most household appliances.
Maximum Power Point (MPP):
The point on the current-voltage (I-V) curve where a solar cell or panel operates at its maximum efficiency and power output.
Monocrystalline Solar Cell:
A type of solar cell made from a single crystal structure, known for its high efficiency.
Net Metering:
A billing arrangement that allows solar panel owners to receive credit for excess electricity they generate and feed back into the grid.
PERC (Passivated Emitter Rear Cell):
PERC is an advanced solar cell technology in which the rear side of the solar cell is passivated to improve efficiency. This technology has become a standard in the solar industry in recent years.
Perovskite Solar Cell:
Perovskite solar cells are a promising and emerging type of solar cell that incorporate perovskite materials such as methylammonium lead iodide (MAPbI3). These materials have the potential to achieve high efficiencies and are comparatively inexpensive to manufacture. Perovskite solar cells are still in the research and development phase, but they have attracted the interest of the scientific community due to their rapid progress and high efficiency potential.
SHJ/HJT (Heterojunction Technology):
HJT is a solar cell technology that uses different layers of material with different band gaps to increase efficiency. This technology combines amorphous silicon with crystalline silicon to achieve higher efficiency.
Photovoltaic (PV) Cell:
A device that converts sunlight directly into electricity using the photovoltaic effect.
Polycrystalline Solar Cell:
A type of solar cell made from multiple crystal structures, slightly less efficient but more cost-effective than monocrystalline cells.
Solar Efficiency:
The percentage of sunlight converted into usable electrical energy by a solar cell or panel.
Solar Irradiance:
The power per unit area received from the Sun in the form of electromagnetic radiation.
Solar Panel:
A collection of solar cells that are used to generate electricity from sunlight.
Solar Spectrum:
The distribution of electromagnetic radiation emitted by the Sun, ranging from infrared to ultraviolet wavelengths.
Tandem Cells:
Tandem solar cells consist of multiple layers of different materials with different band gaps. These layers are stacked on top of each other to better utilize the spectrum of incoming sunlight. By combining materials with different absorption properties, tandem solar cells can achieve higher efficiencies than conventional solar cells.
Thin-Film Solar Cell:
A solar cell made by depositing one or more thin layers of photovoltaic material on a substrate, known for its flexibility and versatility in applications.
Topcon (Tunnel Oxide Passivated Contact):
Topcon is a solar cell technology in which the front and back sides of the cell are passivated with a thin oxide layer to reduce electrical resistance and increase efficiency.
