According to a report on the British "Guardian" website on August 15th, by next summer, British roofs may be equipped with breakthrough solar panels, using a crystal that was first discovered nearly 200 years ago to help use more Solar energy. An Oxford-based solar technology company hopes to start manufacturing the most efficient solar panels in the world by the end of the year and become the first company to sell these solar panels to the public within next year. According to the report, Oxford Photovoltaic Solar Company said that by coating the solar panels with a thin layer of crystalline material called perovskite, they will increase the power generation of next-generation solar panels by nearly 1/3 compared with traditional silicon-based solar panels. . This breakthrough will bring about the first great change in the field of solar power generation since the advent of solar technology in the 1950s. Coating traditional solar cells with a thin layer of perovskite can increase their power generation and reduce the overall cost of clean electricity, because this crystal can absorb different parts of the solar spectrum and has better performance than traditional silicon. The report pointed out that in general, silicon solar cells can convert up to about 22% of the available solar energy into electricity. But in June 2018, Oxford Photovoltaic Solar’s ​​"perovskite-on-silicon" solar panels surpassed the best performance solar panels using only silicon, setting a record that could convert 27.3% of the available solar energy into electricity. new record. The appearance of solar panels with perovskite coating will also be different. Oxford Photovoltaic Solar’s ​​panels will be black (instead of the blue that traditional silicon panels usually show) and will be better integrated with roof slabs.
