# The Future of Solar Power

## Where Solar Technology Is Headed
Cheap, highly efficient PV cells have long been the goal of the [solar energy industry](https://halcolenergy.com.au/solar-battery-package/), and perovskite solar cells emerged as a promising technology working toward exactly that.

Current [solar panels](https://halcolenergy.com.au/) are made from silicon, which makes them expensive to produce; they can also only achieve 20% efficiency at best, which is why researchers are looking for better alternatives.

One such alternative is the perovskite cell. Perovskite is a specific type of crystalline structure – one example of a perovskite material is calcium titanium oxide, but there are many others.

## Perovskite advantage
The silicon crystals used in PV cells have to be produced at high temperatures with very precise techniques. Perovskite cells are simpler to produce and can be made at around room temperature – much cheaper.

At present, the perovskite cells are managing around 20% efficiency, the same as silicon, but this is set to improve and some developers believe that these models will overtake silicon in the next 10 years. Others believe that perovskite and silicon could work together. The two materials capture different light wavelengths, so layering perovskite over silicon could convert larger segments of the sun’s spectrum at once.

It’s not just about the efficiency, though, as perovskite crystals can be transparent, unlike silicon, so they can be used in windows.

## Too good to be true?
It may be a while until perovskite cells are commonplace because there’s a lot to be straightened out first. The 20% efficiency levels are in lab conditions only and so far, developers haven’t managed to make cells any larger than a square centimetre.

Researchers are making progress, however, and are trying new techniques to produce larger cells, comparable to our silicon ones. Another barrier, though, is the fact that perovskite isn’t as stable as silicon – humidity or rain can cause the cells to degrade in a matter of days. There will need to be a way of sealing the cells so no water gets to them for at least 25 years, which takes us well into the future…
