When solar cells are exposed to sunlight, certain bound 'charge pairs' are generated in its components, which need to be separated for photocurrent generation. Ferroelectric materials, due to their ...

A joint research team led by Dr. Hee-Eun Song of the Photovoltaics Research Department at the Korea Institute of Energy Research (President Yi Chang-Keun, hereafter “KIER”) and Prof. Ka-Hyun Kim of ...

New control achieved over perovskite solar cell crystallization with record efficiency and long-term stability. Study: Polarize the Solvent to Regulate the Intermediate Phase and Dynamic ...

A series of sulfides/carbon composites with sulfur vacancies-rich sulfides heterointerfaces are well-designed and developed via a simple one-pot carrageenan-assistant cations-regulated strategy.

Korean researchers revealed that efficiency losses in heterojunction solar cells arise from two coexisting defect types – dangling bonds and weak silicon-silicon bonds. Their findings explain how ...
