A collaborative project undertaken by researchers from ICIQ’s Palomares and Vidal groups, the Physical Chemistry of Surfaces and Interfaces group at the Institut de Ciència de Materials de Barcelona (ICMAB-CSIC) and IMDEA Nanociencahave has examined the interfaces in perovskite solar cells to better understand the impact that changing the materials used in such cells has on its performance.

Perovskite solar cells with different materials as HTMs

This work sheds light on the reasons behind the differences observed in perovskite solar cells’ performance by comparing four different HTMs that present close chemical and physical properties.

A joint research team including scientists from the Chinese Academy of Scinces (CAS), Shijiazhuang Tiedao University in China and Chiao Tung University in Taiwan has developed a novel type of highly flexible and stable perovskite-based solar cell that could be used in wearable electronics.

The team stated that current PSCs are mainly made of a polymer substrate, which has been proven fragile, unstable and not adequately waterproof. The team built a new type of PSC based on an inorganic mica substrate, which could reduce the strain in the device even under large bending deformation. Mica is a mineral that separates easily into small flat transparent pieces of rock.
