Solar cell technology is an electrical device that converts the energy of light directly into electricity through the photovoltaic effect. It is a form of photoelectric cells, and a device whose electrical characteristics, such as current, voltage, or resistance, changes when near to light.
Solar cells are photovoltaic, whether the source is sunlight or an artificial light. Hence, they are helpful in photodetector detecting light and measuring light intensity.
It has three basic characteristics:
- Absorption of light
- Separation of charge carriers of opposite types
- Extraction of an external circuit
Future of Solar cell Technology
More people install photovoltaic systems, the solar technology industry is growing rapidly. Due to the government cutting all subsidies for solar panels in March 2019, solar technology continues to be popular due to fall in price. Due to high electricity prices it is a good time to invest in PV technology. Scientists have been working on solar cells for better results. Solar cells that use this material are more efficient than current solar panels.
Generation of solar cell technology
Following are the three generations of solar cell technology:
First Generation of Solar Cells
They are made from silicon. They are currently the most efficient solar cells available for residential use and around 80+ percent of all the solar panels sold worldwide. Silicon-based solar cells are more efficient and long-lasting instead of non-silicon-based cells.
Following are the four types of silicon-based cells used for the residential purpose:
- Monocrystalline Silicon Cells
2. Polycrystalline Silicon Cells
3. Amorphous Silicon Cells
4. Hybrid Silicon Cells
Second Generation of Solar Cells
Thin film Solar Cells are the Second generation solar cells. Using less material and lower cost producers and thus sells panels at a lower cost.
The following are three types of solar cells
2. Cadmium Telluride (CdTe)
3. Copper indium gallium diselenide (CIGS)
Third Generation of Solar Cells
Third-generation solar cells are made from nanotubes, silicon wires, and solar inks. Moreover, Most of the third-generation solar cell work is done in the laboratory by new companies.
Effectiveness of solar cell technology
Solar panel efficiency is just a measurement of a solar panel that converts sunlight into electricity. For example, if the sun shines on a high-efficiency solar panel, then the sun’s energy will be converted to solar energy.
Solar panel efficiency is determined by the production of electricity by solar cells only. However, The standard for efficiency is only rising in 2021 due to new technologies and manufacturing capabilities.
Best Solar Panel Manufacturers:
Following are the top five best solar panel manufacturers:

Different types of solar cell technology
Since Two most common types are Monocrystalline and Polycrystalline. These counterparts also have other distinctive variables that give a better overview and attract user choice.
Monocrystalline solar panels
Though, Monocrystalline solar panels are considered a premium solar product with relatively high efficiency. These panels are created on the basis of the most developed technology used for a long.
The following are the main characteristics of monocrystalline solar panels:
- Performance Efficiency
- Space Efficiency
Polycrystalline Solar Panels
Polycrystalline solar panels, also known as multi-crystalline solar panels have comparatively newer technology and were first introduced in 1981. Unlike monocrystalline panels, the Czochralski process is not followed in the making of these panels.
However, the work of polycrystalline solar panels suffers in certain climate conditions like snowy weather or low light. Their performance drops when the temperature rises high.
