“…They analyzed the influence of series and shunt resistance on the performance of OSCs. Similarly, CuI-doped P3HT:PCBM-based OSC have been developed with a PCE of ~5% under white LED lamp [28]. The improved performance was attributed to the better hole selecting behavior and decreased charge carrier recombination.…”

Organic solar cells (OSCs) have become a potential energy source for indoor light harvesting in recent years as they have witnessed a record power conversion efficiency (PCE) of over 30% under indoor lights. Among various strategies, interlayer engineering is one of the important factors in improving the performance of OSCs. Here, we reported an efficient OSC based on PM6:Y6 photoactive layer showing an excellent PCE of ~22% and ~14% under light-emitting diode (LED, 1000lx) and 1-sun (AM1.5 G) conditions respectively. The performance of OSCs was optimized by systematically investigating the optical, electrochemical, and morphological characteristics of three different cathode interlayers (CILs) named as: PEIE, ZnO, and ZnO/PEIE (bilayer). The high transmittance (~90%), suitable work function (~4.1 eV), and improved surface morphology (RMS: 2.61 nm) of the bilayer CIL contributes in improving the performance of OSCs. In addition, the suppressed charge recombination and improved charge carrier transport are attributed to high shunt resistance and appropriate energy levels alignment between photoactive layer and bilayer CIL. The findings in the study might provide guidelines for designing novel interlayers in the development of efficient OSCs for different illumination conditions.

“…One of the reasons is due to the absorption of P3HT: PCBM used in this device can absorb the 500 nm wavelength region, where most of the studies show that the absorbance of this blend layer for 100 nm thickness is around 80% within the 500-550 nm wavelength region. [19][20][21][22][23][24] It also has a very low transmittance, less than 30%. 17) Therefore, the internal reflection from the Al top contact cathode is assumed to be negligible in this study.…”

The organic photodetectors (OPDs) with an interdigitated electrodes (IDEs) structure are analyzed to evaluate the optical crosstalk between neighboring pixels for the organic image sensor used in the fingerprint-on-display (FOD) authentication system. The shorter exciton diffusion length of organic semiconductors in the OPD can promote the high resolution of the organic image sensor for full-display sensing applications. We demonstrated the photocurrent diffusion from the exposed area to the hidden electrodes by changing the distance to predict the minimum pixel pitch for the organic image sensor. Unexpectedly, the photocurrent diffusion was observed, even at 10 µm length, as more significant than the expected exciton diffusion length.

“…The following year, Luo et al [48] reported a fluorine-containing Lewis acid dopant as an effective substitute for TFSI/TBP additives for PTAA-polymeric HTL that not only improved the device efficiency but also induced long-term device stability. Likewise, many other alternative dopants such as acid additives (e.g., phosphoric acid) [261], Ag-TFSI [61], spiro-(TFSI) 2 [155], copper salts (e.g., CuI or CuSCN) [25,262], and F4-TCNQ [263,264] were proposed in several research works as promising candidates to improve the overall performance and long-term stability of PSCs.…”

Perovskite solar cells (PSCs) have captured the attention of the global energy research community in recent years by showing an exponential augmentation in their performance and stability. The supremacy of the light-harvesting efficiency and wider band gap of perovskite sensitizers have led to these devices being compared with the most outstanding rival silicon-based solar cells. Nevertheless, there are some issues such as their poor lifetime stability, considerable J–V hysteresis, and the toxicity of the conventional constituent materials which restrict their prevalence in the marketplace. The poor stability of PSCs with regard to humidity, UV radiation, oxygen and heat especially limits their industrial application. This review focuses on the in-depth studies of different direct and indirect parameters of PSC device instability. The mechanism for device degradation for several parameters and the complementary materials showing promising results are systematically analyzed. The main objective of this work is to review the effectual strategies of enhancing the stability of PSCs. Several important factors such as material engineering, novel device structure design, hole-transporting materials (HTMs), electron-transporting materials (ETMs), electrode materials preparation, and encapsulation methods that need to be taken care of in order to improve the stability of PSCs are discussed extensively. Conclusively, this review discusses some opportunities for the commercialization of PSCs with high efficiency and stability.
