Journal ArticleDOI
Perovskite solar cells with a planar heterojunction structure prepared using room-temperature solution processing techniques
Dianyi Liu,Timothy L. Kelly +1 more
TL;DR: The use of a thin layer of zinc oxide nanoparticles as an electron-transport layer allows flexible perovskite solar cells to be fabricated with a power conversion efficiency as high as 15.7% as mentioned in this paper.
Journal ArticleDOI
Investigation of CH3NH3PbI3 Degradation Rates and Mechanisms in Controlled Humidity Environments Using in Situ Techniques
TL;DR: This work demonstrates the formation of a hydrated intermediate containing isolated PbI6(4-) octahedra as the first step of the degradation mechanism, suggesting a route toward perovskite solar cells with long device lifetimes and a resistance to humidity.
Journal ArticleDOI
Origin of the Thermal Instability in CH3NH3PbI3 Thin Films Deposited on ZnO
TL;DR: In this article, the authors systematically investigated the origin of the thermal instability of perovskite solar cells fabricated using ZnO electron transport layers, and they showed that the basic nature of the znO surface leads to proton-transfer reactions at the CH3NH3PbI3 interface.
Journal ArticleDOI
Compact Layer Free Perovskite Solar Cells with 13.5% Efficiency
TL;DR: A new type of compact layer free bilayer perovskite solar cell is reported and it is conclusively demonstrated that the ETL is not a prerequisite for obtaining excellent device efficiencies.
Journal ArticleDOI
Effect of CH3NH3PbI3 thickness on device efficiency in planar heterojunction perovskite solar cells
TL;DR: In this paper, the perovskite solar cells based on a ZnO nanoparticle electron transport layer, CH3NH3PbI3 light absorber, and poly(3-hexylthiophene) (P3HT) hole transport layer are presented.
