Review of light induced degradation in silicon published today

Our review on "Light induced degradation in crystalline silicon" has been published today in Solar Energy Materials & Solar Cells

Although several advances have been made in the characterization and the mitigation of light-induced degradation (LID), industrial silicon solar cells still suffer from different types of light-induced efficiency losses. This review compiles four decades of LID results in both electronic- and solar-grade crystalline silicon. The review focuses on the properties and the defect models of boron-oxygen LID and copper-related LID. Current techniques for LID mitigation are presented in order to reduce cell degradation and separate copper-related LID from boron-oxygen LID. Finally, the review summarizes recent observations of severe LID in modern multicrystalline silicon solar cells.

Time off work - the biggest reason why fewer women are CEOs

Women are underrepresented in CEO positions partly because they spend more time outside of the labour market during the years when their careers are most likely to take off. Women also less often work in sales or production, which are common pathways for CEO recruitment.
