Common Materials Used In Solar Energy Production

Solar energy is the heat and light that comes from the sun. People can use the sun’s energy in different ways. A solar energy system is one of the best ways to save money on electricity bills. Several materials are used in the production of solar in Pakistan. These include organic materials, III-V semiconductors, Perovskites, and Graphene. These materials are commonly used in domestic solar panels. We will discuss some of these materials and their applications in solar energy below.

Perovskites:

Perovskites are a class of crystalline semiconductors. They can be tuned to produce an ideal “bandgap,” or the amount of energy needed to push an electron up an energy level. In an electron orbit, a positively-charged atom attracts a neighboring negatively-charged electron. Each atom’s number of electrons determines the type of molecule it forms. The outermost electrons are in the valence band.

Researchers are working on fine-tuning perovskites to improve the performance of solar cells. They are also investigating protective layers and stabilizers to extend the lifespan of perovskites. However, it will likely take another decade or more of research before perovskites can reach a commercial level.

III-V semiconductors:

III-V semiconductors are a flexible group of materials well suited for optoelectronic applications. They are also ideal for making high-efficiency solar cells. This is due to the single junction concept that has been in use since the early days of photovoltaics. This class also allows for bandgap engineering, which allows the cell to be tailored to different spectra.

Graphene:

Graphene is a monoatomic layer of carbon atoms. It has an extremely high surface area and is the strongest material on Earth. When solar energy hits the material, it causes electrons to remain on the surface for some time. This allows the material to be a highly efficient conductor of electric current.

Organic materials:

Most organic materials used in solar cells have dead-end pathways that limit power production. However, the UW team was surprised that their material had only a few such pathways. That meant they needed more sensitive measurements to determine the reason behind their findings. In the meantime, researchers had observed similar behavior in similar materials and had discovered features that no one had thought possible.
