110. Perovskite Solar Cells Improved, Cancer Fighting Cells, Most Efficient Passenger Plane

<p>SHOW NOTES</p> <p>01:50 <a href='https://interestingengineering.com/perovskite-solar-cell-commercially-viable-lifetime'>The first perovskite solar cell with a commercially viable lifetime is here</a> | Interesting Engineering </p> <ul><li style="font-weight:400;">A team of researchers from Princeton University has built the first perovskite solar cells that last long enough to be commercially viable.<ul><li style="font-weight:400;">Silicon-based cells, which many regard as an expensive and suboptimal component, have dominated the renewable energy market since their introduction in 1954.</li> <li style="font-weight:400;">This new technology, which is not only incredibly durable but also meets common efficiency standards, has the potential to change that.</li> <li style="font-weight:400;">Expected to outperform industry norms for roughly 30 years, well beyond the 20-year criterion for solar cell viability</li> </ul> </li> <li style="font-weight:400;">Perovskite solar cells are regarded as high-efficiency, low-cost modular technology for implementation in the renewable power industry. <ul><li style="font-weight:400;">Less Energy = Less $$$</li> </ul> <ul><li style="font-weight:400;">Would become more fragile in that case</li> </ul> <ul><li style="font-weight:400;">The name “perovskite” comes from the nickname for their crystal structure.</li> <li style="font-weight:400;">Can be manufactured at room temperature, which means they need less energy than manufacturing silicon. </li> <li style="font-weight:400;">Can be modified to be flexible and transparent</li> </ul> </li> <li style="font-weight:400;">The new device created by these researchers estimated lifetime is a five-fold increase over the previous record, which was established by a lower efficiency perovskite solar cell in 2017.</li> <li style="font-weight:400;">Additionally they created a new testing method allowing them to test the longevity of these particular types of solar cells. <ul><li style="font-weight:400;">Ranging from a regular summer day's baselin
