Perovskite solar cells hold an advantage over traditional silicon solar cells in the simplicity of their processing and their tolerance to internal defects.
Perveskite solar panel.
A perovskite is any type of material that has the same crystal structure as calcium titanium oxide catio 3.
Within solar lead is often the dominant metal used in perovskites.
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.
Home perovskite solar cells.
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.
The material can be cheaply laminated onto the glass layer of solar panels from a solution.
Perovskite is a thin flexible and lightweight crystal structure.
Perovskite has a good tolerance of defects and impurities in contrast to silicon so the material can be deposited simply by printing or spraying.
Traditional silicon cells require expensive multi step processes conducted at high temperatures 1000 c under high vacuum in special cleanroom facilities.
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.
