A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...

with the best organic solar cells, which are based on a so-called conventional structure, reaching over 20% in the lab. However, the employed materials are susceptible to degradation when exposed ...

A multi-junction solar cell developed by NREL. It glows red due to gallium indium phosphide in the top layer. Credit: NREL The physics involved ... This isn’t just lab technology, either.

Combining two semiconductor thin films into a tandem solar cell can achieve high efficiencies with a minimal environmental footprint. Teams have now presented a CIGS-perovskite tandem cell that sets a ...

Scientists in the lab of Professor Ted Sargent have developed a new method to improve the stability and efficiency of perovskite solar cells (PSCs), a promising alternative to traditional silicon ...

It could enhance the problem-solving capabilities of computers, develop more efficient solar power cells, and both identify ... of the 2023 Nobel prize in physics—involves using such almost ...

The new record was achieved on a 9cm2 tandem perovskite silicon solar cell compared to most records achieved on 1cm2 cells.
