Making sense of failure in light-harvesting semiconductors

Thursday, September 8, 2016 - 06:31 in Physics & Chemistry

While metal oxide semiconductors have been widely considered to exhibit outstanding durability, performance degradation in these solar energy harvesting components is frequently observed. Understanding the degradation is essential for developing stable, efficient photosystems. To address the failure, a team at the Joint Center for Artificial Photosynthesis uncovered the mysteries of photochemical instability in a widely used semiconductor. Their results reveal previously unpredicted pathways to degradation and provide insights.
