6 FAQs about [Ir photovoltaic cell]
Can silicon photovoltaic cells convert infrared light into electricity?
They show that its efficiency is competitive with that of steam boilers, and it avoids the use of moving parts and water that might otherwise be scarce. Silicon photovoltaic cells—and those made from a range of other materials—can convert infrared light into an electrical current. They just don't do so efficiently.
How do photosensitive materials respond to infrared light?
Photosensitive materials used in solar cells, such as the mineral perovskite, have a limited ability to respond to infrared light. The solution, developed with KTH researchers Haichun Liu and Qingyun Liu, was to combine nanocrystals with chains of microlenses.
