A detailed review of perovskite solar cells
Emerging photovoltaic devices based on molecular and nanomaterials are mostly excitonic in nature. The initial absorption of a photon in these materials creates an exciton that can subsequently dissociate in each material or at their interfaces to give charge carriers. Any attempt at mechanistic understanding of excitonic solar cells must start with …

Traditional inorganic solar cell models, originating with the work of Shockley, are widely used in understanding bulk heterojunction (BHJ) organic solar cell response (organic solar cells are also referred to as organic photovoltaics, or OPVs). While these models can be useful, there are several key points o

The four bonding orbitals cannot result from a simple overlap of the three orthogonal p-orbitals and the single symmetric s-orbital of the binding partners. They constitute four new orbitals, called sp (^3) (Fig. 3.1b), because they result from an overlap of the s- and the three p-orbitals of the C atom. ...

Conjugated Systems We start our study of covalent bonding with a simple hydrocarbon, the methane CH (_4): The central carbon atom with four valence electrons shares one with each hydrogen, also delivering one electron for the bond, which is represented by a line in the Lewis structure of Fig. 3.2a. a.
Organic solar cells (OSCs) based on a symmetry-breaking strategy have received lots of attention in recent years. In addition to the symmetry-breaking innovation of acceptors, researchers have also made great contributions to the development of high-performance OSCs through continuous optimization and improv
