Monolithic CIGS-Perovskite Tandem Cell for an Optimal Light Harvesting Without Current Matching [PDF]

, 2017
We present a novel monolithic architecture for optimal light harvesting in multijunction thin film solar cells. In the configuration we consider, formed by a perovskite (PVK) cell overlying a CIGS cell, the current extracted from the two different ...

Chemical and Structural Diversity of Hybrid Layered Double Perovskite Halides [PDF]

Journal of the American Chemical Society, 2019
Hybrid halide double perovskites are a class of compounds attracting growing interest because of their richness of structure and property. Two-dimensional (2D) derivatives of hybrid double perovskites are formed by the incorporation of organic spacer cations into three-dimensional (3D) double perovskites.

(INVITED) Revisiting Duffy's model for Sb3+ and Bi3+ in double halide perovskites: Emergence of a descriptor for machine learning

Optical Materials: X, 2021
The Duffy's model is reformulated for Sb3+ and Bi3+ in cubic chloro- and bromo-elpasolites with « 0D » perovskite structure. The new equation allows calculating the energy of the first s2 → s1p1 electron transition from crystal structure data. The Stokes

Enhancing the photophysical properties of absorption and luminescence in lightly doped halide double perovskite nanomaterials (Cs2Ag1-aBi1-bPbxBr6): Theory and experiment

Next Materials
Lead-free halide double perovskites, such as Cs2AgBiX6, have emerged as less toxic alternatives to the lead-based solar cell absorbers, APbX3 (where A is a monovalent cation and X is halide). Despite their potential application in photovoltaics and x-ray
