Solar power has become one of the most popular sources of renewable energy. Over the past few years, the cost of solar panels has dropped a lot, making them more affordable for both homes and businesses. But will solar power get even cheaper in the future? Scientists believe the answer is yes – and a big reason is a new type of material called perovskites.
What Are Solar Panels Traditionally Made From?
Traditional solar panels are mostly made with silicon, a strong and reliable material, but it has some downsides. It’s expensive to make, needs high temperatures to process, and requires a lot of energy and special equipment to create. These things make the final price of solar panels higher, as they cost quite a bit to make.

What Are Perovskites?
Perovskites are a group of materials that could change how solar panels are made. They are named after a mineral discovered in the 1800s, but scientists have recently started using them in solar technology. Perovskites can be made in labs using cheaper materials and at lower temperatures than silicon. This means they could help bring down the cost of making and producing solar panels.
How Perovskites Help Save Money
One of the best things about perovskites is that they can absorb sunlight very well – even better than silicon in some cases. Because they’re so efficient, perovskite solar panels could create more energy using less material. Also, these materials can be printed onto surfaces, making it easier to create flexible or lightweight solar panels. All of this could lead to faster and cheaper solar panel production.
Future Challenges
One big issue of perovskites is that they don’t last as long as silicon. Some perovskite panels stop working after a few years, while silicon panels can last more than 25 years. Scientists are working hard to solve this problem in the future.
