Russia develops semi-transparent solar panels that generate electricity and transmit light, leading the future architectural aesthetics

On August 6, the science and technology community reported new progress. The Russian National Research University of Technology announced a breakthrough: they successfully developed an innovative method to integrate indium tin oxide (ITO) transparent electrodes into perovskite solar cells in a new way, which not only significantly improved the efficiency of the cells, but also gave them the unique property of semi-transparency.

For a long time, the field of perovskite solar cells has relied on magnetron sputtering technology to deposit the ITO transparent electrode layer, but this technology has significant drawbacks: the quality of the deposited layer is uneven, there are many defects, and it is easy to damage the fragile perovskite layer and other components of the battery, which seriously hinders the further improvement of the overall efficiency of the battery.

Faced with this technical bottleneck, the Russian scientific research team dared to explore and adopted the cutting-edge ion beam sputtering technology as an alternative. This technology cleverly avoids the need for high-temperature treatment and gently protects the integrity of the structure of each layer of the battery, allowing the ITO layer to be deposited on the perovskite solar cell with unprecedented high quality, showing a remarkable performance leap.

The experimental data is exciting: the photoelectric conversion efficiency of semi-transparent perovskite solar cells prepared by ion beam sputtering technology has achieved an amazing leap from 3.12% to 12.65%. This huge improvement not only verifies the effectiveness and advancement of the new technology, but also paves a solid path for the future development of perovskite solar cells.

Even more impressive is that this achievement is not limited to the improvement of efficiency, it also opens a new era of solar cell applications. The manufacture of high-performance tandem solar cells has become possible. By integrating a variety of photosensitive materials, these cells can capture a wider range of spectra, greatly enhancing the efficiency of solar energy utilization. At the same time, the introduction of semi-transparent properties has brought revolutionary changes to the field of architectural design. Solar cells are no longer limited to traditional forms, but can be cleverly integrated into windows, exterior walls and other corners of buildings, achieving a harmonious coexistence of energy production and architectural aesthetics.
