Perovskite photovoltaic cells in space probes? Only one change is needed to make it possible

Advanced Energy Materials publishes a scientific paper written by an international team of researchers led by engineers from the University of Surrey, UK. In it, they present a slight modification in the structure of inverted perovskite solar cells (IPSCs), which will allow the release of unprecedented potential in this material.

Perovskites in photovoltaic cells are synthetic materials whose name refers only to a group of naturally occurring minerals. Perovskite photovoltaic cells have a different composition than the mineral counterpart, but the structure is similar. It is in this material that one sees hope for the future of the photovoltaic industry, which is looking for cheaper, lighter, simpler and more accessible means of building solar panels.

Perovskite photovoltaic cells will reach a new level

As we learn from the article, scientists have successfully manipulated the surface of a perovskite with a halide composition, which leads to an interaction between the so-called modulators and perovskites. They showed that a high-impact surface modulator is useful in reducing IPSC losses.

The study was conducted on two ammonium salts, which consist of 4-hydroxyphenethylammonium iodide and 2-thiophenethylammonium iodide (2-TEAI).

Dr Wei Zhang, Principal Research Officer at the University of Surrey, commented on the results, adding that the future of IPSCs is also in space:

Our work will contribute to the understanding of the complex interaction between passivators (modulators) and perovskites at the material interface. This will take perovskite photovoltaics to a whole new level. (…) The future of perovskite solar panels is extremely exciting with the promise of not only improving the efficiency of solar farms and rooftop panels, but also many possibilities for powering spacecraft and interstellar probes.
