Perovskite solar cells are heralded as the natural successors to silicon. The bulky but effective plastic-based solar technology component may find a good competitor in the affordable and compact perovskite cells. Today’s studies and progress in the technology all indicate Perovskite’s enormous role in becoming the standard household material for solar panel development.
The Australian National University (ANU) had developed a perovskite cell that broke its previous record after achieving a 22% solar energy acquisition rate using a 1 square centimeter solar cell. Single-crystal cells, such as silicon, can achieve a 25% solar energy acquisition rate. However, with perovskite’s affordability and increasing efficiency, it’s highly likely that solar panels can become much more affordable and easier for manufacturers to create.
The efficiency of solar panels is important because it is a measure of how much energy is absorbed by the panels in comparison to the energy put into them. Efficiency is an important factor in the success of solar technology, as more efficient panels have a greater potential for producing electricity. Throughout their activities, solar panel manufacturers continue to make great strides to help homeowners achieve exceptional energy efficiency at home.

The industry standard for solar electric systems is based on photovoltaic, or PV, technology, which converts sunlight into electricity. Multiple solar cells are interconnected to create a module, which comprises the panel.
Each panel is usually connected together in a system in which electricity is sent to an inverter to provide the power needed to run household electric devices. Efficiency is often dependent on the design of the panel and how it is engineered to capture different frequencies of light energy. Consider the following designs:
Monocrystalline Silicon Panels
The most efficient type of photovoltaic solar panel available today is currently monocrystalline, or single, silicon panel. Because of the higher silicon content used in the design, they are more expensive than alternative types of panels. More energy is converted into electricity, so fewer panels are needed in most roof installations to meet the same power requirements. These types of square-shaped panels are ideal for roof mounted solar electric systems.
Polycrystalline Silicon Panels
With lower amounts of silicon utilized in polycrystalline, or multi-layered, silicon panels, they are often cheaper than their more efficient counterparts. They implement a design to help reduce this efficiency loss, allowing them to be utilized on roof mounted systems. This makes them ideal for larger projects and installations because they cost less. Polycrystalline silicon panels are also resistant more resistant to heat.
Building Integrated Photovoltaic Panels
Appearance is an important aspect of a building. As with many historic buildings, or ones that feature unique architectural designs, owners might be hesitant to alter the distinctive character of a structure by installing a solar electric system. To help mitigate the aesthetic changes that solar panels might bring, building integrated photovoltaics are available. While they may be able to keep the look of traditional roofing, these types of panels are more costly and less efficient than the alternatives.
Thin-Film Solar Cell Technology
Thin film cells are a newer photovoltaic technology that consists of one or multiple layers of thin films of photovoltaic cells that are laminated to existing material, such as metal roofing or glass windows. These photovoltaic films are very thin allowing them to be lighter and more flexible compared to other PV systems. While thin-film technology is extremely versatile, it comes at a cost. Thin-film systems are less efficient and can degrade faster than conventional solar systems, but are improving with technology advancements. (Continue reading here to learn more)
