While perovskite solar cells have become highly efficient in a very short time, a number of challenges remain before they can truly become a competitive commercial technology.\u003C/p\u003E\n\u003Cp\u003E\u00A0\u003C/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EResources\u003C/strong\u003E\u003C/p\u003E\n\u003Cp\u003E1.\u003Cstrong\u003E\u003Ca href=\u0022https://www.youtube.com/watch?v=5oZWLKSDVBk\u0022\u003E WATCH\u003C/a\u003E\u003C/strong\u003E a video on Perovskite Solar Panels\u003C/p\u003E\n\u003Cp\u003E2. \u003Cstrong\u003E\u003Ca href=\u0022mailto:hello@magnetgroup.co.za?subject=Solar%20Enquiry\u0022\u003ECHAT\u003C/a\u003E\u003C/strong\u003E to our solar experts about a clean energy solution for your home, factory or office\u003C/p\u003E\n\u003Cp\u003E\u00A0\u003C/p\u003E\n\u003Cp\u003E\u00A0\u003C/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ESource:\u003C/strong\u003E\u003C/p\u003E\n\u003Cp\u003E\u003Ca href=\u0022https://www.cei.washington.edu/education/science-of-solar/perovskite-solar-cell/\u0022\u003Ehttps://www.cei.washington.edu/education/science-of-solar/perovskite-solar-cell/\u003C/a\u003E\u003C/p\u003E\n\u003Cp\u003E\u003Ca href=\u0022https://www.energy.gov/eere/solar/perovskite-solar-cells\u0022\u003Ehttps://www.energy.gov/eere/solar/perovskite-solar-cells\u003C/a\u003E\u003C/p\u003E\n\u003Cp\u003E\u00A0\u003C/p\u003E\n", "created": "Sep 2021", "terms": "Solar, Education" } ]
