Study unlocks nanoscale secrets for designing next-generation solar cells

The work will help researchers tune surface properties of perovskites, a promising alternative and supplement to silicon, for more efficient photovoltaics.

Perovskites, a broad class of compounds with a particular kind of crystal structure, have long been seen as a promising alternative or supplement to today’s silicon or cadmium telluride solar panels. They could be far more lightweight and inexpensive, and could be coated onto virtually any substrate, including paper or flexible plastic that could be rolled up for easy transport. In their efficiency at converting sunlight to electricity, perovskites are becoming comparable to silicon, whose manufacture still requires long, complex, and energy-intensive processes. One big remaining drawback is longevity: They tend to break down in a matter of months to years, while silicon solar panels can last more than two decades. And their efficiency over large module areas still lags behind silicon. Now, a team of researchers at MIT and several other institutions has revealed ways to optimize efficiency and better control degradation, by engineering the nanoscale structure of perovskite devices.

I'm working on a longer piece about perovskite solar cells, but one of the key obstacles to their commercial success is the presence of lead. Researchers at Pusan National University think they've found a passivation solution to prevent lead leakage. Technical details here.

These materials were meant to revolutionize the solar industry. Why hasn't it happened?

These materials were meant to revolutionize the solar industry. Why hasn’t it happened?

But stability remains a tough challenge.  In one recent study, published in Science in April, researchers discovered a new way to build perovskite solar cells with additives that improved efficiency and lifetime. The cells withstood 1,500 hours of high heat and humidity in the lab.  The problem is translating these results into the real world. It’s hard for researchers to simulate real-world…

Researchers hijack solar cell technology to develop a simple spray test for lead

AMOLF researchers have used the special properties of perovskite semiconductors to develop a simple spray test to demonstrate the presence of lead. Perovskite is a material suitable for use in LEDs and solar cells, for example. A lead-containing surface shines bright green when it is sprayed with the test. This test is 1,000 times more sensitive than existing tests and the researchers found no false positive or false negative results. The study was published on November 27 in the journal Environmental Science & Technology. "We have hijacked the technology of perovskite semiconductors and used it in a widely deployable lead test. Nobody in this discipline had ever thought of that," says Lukas Helmbrecht, researcher at the group Self-Organizing Matter led by Wim Noorduin at AMOLF. "We are very pleased with these results," says Noorduin. "It is a really cool project and it is quite rare for fundamental research to literally impact the entire world with an application."

Imagine creating solar panels without relying on materials in short supply and adopting an eco-friendlier production process. And at the same time boosting efficiency? Enter perovskite tandem solar cells—an innovation that has long held the promise of revolutionizing the solar energy landscape. But where are they in their development, and could they truly represent the future of solar panel technology?
