Perveskite Solar Panel

A perovskite is any type of material that has the same crystal structure as calcium titanium oxide catio 3.

The solar energy technologies office supports research and development projects that increase the efficiency and lifetime of hybrid organic inorganic perovskite solar cells as well as evaluate new materials for them. The general chemical formula for perovskite compounds is abx 3 where a and b are cations and x is the bonding anion see how it looks like catio 3. A perovskite is any material that has the same crystal structure as the compound calcium titanium oxide. By coating a traditional solar power cell with perovskite a solar panel can increase its power generation and lower the overall costs of the clean electricity because the crystal is able to absorb different parts of the solar spectrum than traditional silicon.

Solar cells made with perovskites work in a similar fashion to traditional solar panels a semiconductor absorbs solar energy and initiates a flow of electrons which is captured by wiring and converted into usable electricity. Within solar lead is often the dominant metal used in perovskites. Traditional silicon cells require expensive multi step processes conducted at high temperatures 1000 c under high vacuum in special cleanroom facilities. Perovskite solar cells hold an advantage over traditional silicon solar cells in the simplicity of their processing and their tolerance to internal defects.

Perovskite has a good tolerance of defects and impurities in contrast to silicon so the material can be deposited simply by printing or spraying. Perovskite solar cells have shown remarkable progress in recent years with rapid increases in conversion efficiency from reports of about 3 in 2006 to over 25 in 2020.
