End-group modification of terminal acceptors on benzothiadiazole-based BT2F-IC4F molecule to establish efficient organic solar cells

Effect of tailoring π-linkers with extended conjugation on the SJ-IC molecule for achieving high VOC and improved charge mobility towards enhanced photovoltaic applications

“…, 100%). 83 We employed eqn (14) to calculate the fill factor of R and all optimized planned molecules: 84,85 in this equation, normalized open circuit voltage is represented by Normalized V OC is used for the theoretical calculations of FF. V OC represents open circuit voltage and k B is Boltzmann's constant (8.61733 × 10 −5 eV K −1 ).…”

“…The ideal and perfect value for the ll factor is unity (i.e., 100%). 83 We employed eqn (14) to calculate the ll factor of R and all optimized planned molecules: 84,85 All the proposed molecules give FF values that are close to the ideal value for FF with 0.9242 for DL1, 0.8881 for DL2, 0.8848 for DL3, 0.9032 for DL4, 0.9170 for DL5 while 0.9290 and 0.9287 for DL6 and DL7, respectively, as evident from Table 8. DL1, DL6, and DL7 show remarkable improvement in FF compared to the reference SJ-IC.…”

Alteration of the central core of a DF-PCIC chromophore to boost the photovoltaic applications of non-fullerene acceptor based organic solar cells

“…These electrons and holes rapidly set themselves in motion towards their corresponding electrodes before they could recombine. [73][74][75] As a result of this movement, distortion takes place inside the molecular structure, thus the molecule requires some energy to reorganize its structure aer distortion. This energy is called internal reorganization energy (l int ).…”

Theoretical framework for achieving high Voc in non-fused non-fullerene terthiophene-based end-capped modified derivatives for potential applications in organic photovoltaics

“…This technique has already resulted in improved organic solar cell molecules made from pre-existing solar cell molecules. 36 So, seven new W-shaped non-fused organic solar cell molecules were fabricated in this research work by bringing about different changes in acceptor portions of A3T-5 molecule, as shown in Fig. 1.…”
