Osaka Metropolitan University scientists have created a molecule that naturally forms p/n junctions, structures that are vital for converting sunlight into electricity. Their findings offer a promising shortcut to producing more efficient organic thin-film solar cells. Their study is published in Angewandte Chemie International Edition.
How organic solar cells work
Solar cells convert sunlight directly into electricity. Within each cell, two semiconductors—p-type and n-type—form a p/n junction, where the photovoltaic effect performs the conversion.
Organic thin-film solar cells use carbon-based semiconductors instead of the traditional silicon, making them lightweight, flexible, and economic...
