In this video, we’ll explore the world’s fastest-improving new solar technology, and provide an exclusive peek inside the lab of a team working on this breakthrough material. Imagine an inexpensive solution of perovskite crystals that can make a photovoltaic cell so thin, that just half a cup of liquid would be enough to power a house. A solar panel is so lightweight, that it can be balanced atop a soap bubble.

That is known as the holy grail of solar energy. So when will we see perovskite solar panels used for a solar power system for your home? Maybe sooner than you expect. Currently, only 2% of global electricity comes from solar power. And 90% of that, comes from crystalline silicon-based solar panels, the dominant material technology. While abundant, silicon has downsides related to efficiency, manufacturing complexity, and pollution that prevent it from being an absolute no-brainer. Emerging thin films like perovskites present a bright future.

Imagine solar cars like a solar tesla, solar yachts, or a solar plane. Solar cell technologies can be classified into two categories, wafer-based or thin-film cells. Perovskites are the leading contender in emerging thin films. Topics covered in this video include applications, perovskite crystal structure, working principle of perovskite solar cells, efficiency limits, multi-junction solar cells, shockley-queisser limit, how solar works, solar simulator, bandgap, manufacturing, vapor deposition, how solar panels are made, and the future of solar power.
