Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries, where they are ...

Perovskite solar cells have gained considerable momentum in the search for cheaper, more efficient solar energy. However, the ...

Chinese company LONGi has developed crystalline silicon-perovskite tandem solar cells with a 35.5 percent conversion ...

Solar cells' efficiency and lifespan are often determined by what happens at interfaces—the microscopic boundaries where ...

It is common for solar panels to be shaded by trees, clouds, birds or buildings. For thin-film solar technologies, however, ...

Faiz Mandani, a Rice doctoral alum and co-author on the study, helped develop a degradation unit to simulate exposure to heat and irradiance in order to test how devices built from the new perovskite ...

Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. The materials physics shows that this is possible, the same semiconductor ...

Researchers from the University of Arkansas in the United States have fabricated a graphene-based solar cell that can be used in Internet of Things (IoT) applications. The device was developed in the ...

PEDOT:PSS is commonly used as a hole transport layer in perovskite solar cells because it combines high transparency, good conductivity, and suitable energy-level alignment, but its moisture ...
