Black silicon wafers significantly improve efficiency of ultrathin solar cells

By Guest Contributor / August 22, 2023

Reducing the thickness of silicon wafers in solar cells below 40 μm typically results in decreased performance. Using black silicon for the wafer, however, which has a textured surface structure, can improve the wafer’s absorption capabilities. Researchers in Spain and Finland demonstrated this improvement by using ultrathin black silicon wafers to create interdigitated back-contact solar cells.
