🔥INTERESTING FACT🔥
#ENGLISH
The idea of turning windows into working power plants has just moved a little bit closer to reality.
Perovskite cells with a conversion efficiency of 15.5 percent that let through more than 20 percent of visible light have been developed by a team of researchers from the ARC Center of Excellence in Exciton Science under the direction of Professor Jacek Jasieniak from Monash University's Department of Materials Science and Engineering.
The amount of visible light entering through the cells is amazingly now reaching glazing levels, expanding their potential for use in a wide range of real-world applications. This enhances the stability of solar windows while allowing more natural light in.
#HINDI
खिड़कियों को सक्रिय बिजली जनरेटर में बदलने का सपना साकार होने के एक कदम और करीब पहुंच गया है।
मोनाश विश्वविद्यालय के सामग्री विज्ञान और इंजीनियरिंग विभाग के प्रोफेसर जेसेक जसीनियाक के नेतृत्व में एआरसी सेंटर ऑफ एक्सीलेंस इन एक्सीलेंस साइंस के शोधकर्ताओं की एक टीम ने 15.5 प्रतिशत की रूपांतरण दक्षता के साथ पेरोव्स्काइट कोशिकाएं बनाई हैं जो 20 प्रतिशत से अधिक दृश्य प्रकाश की अनुमति देती हैं।
यह अधिक प्राकृतिक प्रकाश की अनुमति देते हुए सौर खिड़कियों की स्थिरता में सुधार करता है, जिसका अर्थ है कि कोशिकाओं से गुजरने वाली दृश्य प्रकाश की मात्रा उल्लेखनीय रूप से अब ग्लेज़िंग स्तर तक पहुंच रही है, जिससे वास्तविक दुनिया के अनुप्रयोगों की एक विस्तृत श्रृंखला में उपयोग की उनकी क्षमता बढ़ जाती है।☀️
