Synthesis, characterization and exploration of photovoltaic behavior of hydrazide based scaffolds: a concise experimental and DFT study

Abstract

Solar energy being a non-depleting energy resource, has attracted scientists' attention to develop efficient solar cells to meet energy demands.

Use of benzothiophene ring to improve the photovoltaic efficacy of cyanopyridinone-based organic chromophores: a DFT study

“…The HOMO of the donor material can be tuned using the LUMO of an acceptor material. 73 The V oc is substantially influenced by the band gap between the donor and acceptor. 74 For open circuit voltage measurements, the polymer molecule i.e.…”

“…The HOMO of the donor material can be tuned using the LUMO of an acceptor material. 73 The V oc is substantially inuenced by the band gap between the donor and acceptor. 74 For open circuit voltage measurements, the polymer molecule i.e., PBDB-T (E HOMO = −5.401 eV and E LUMO = 2.328 eV) is selected as donor and the reference (A1R) and designed molecules (A1D1-A1D5) are considered as acceptors.…”

Rational molecular engineering towards efficient heterojunction solar cells based on organic molecular acceptors

“…[82] To efficiently separate excitons it is necessary to overcome the large exciton binding energy, primarily due to the Coulomb attraction between electrons and holes. [83] Therefore, E b can be assessed by the Coulomb attraction energy (E C ), [57,58] which is based on expression (atomic unit system) [84,85]…”
