“…This is also an important and cost-effective way to manufacturing more precisely designed devices for future development. Recently, some researchers have tried to improve the performance of IOSC devices by optimizing different parameters through modeling and device simulation studies using FDTD-based simulation [75][76][77][78]. They used the Lumerical FDTD software for this, which is a powerful tool for optical modeling of photovoltaic systems.…”

For over a decade, donor-acceptor blends composed of organic donors and fullerene acceptors dominated indoor organic solar cells (IOSCs). Numerous researchers have invested time to conduct extensive studies on developing new donor acceptor materials, interlayers, minimizing energy losses, and enhancing the open-circuit voltage (V OC) through device and material engineering, and optimizing device architectures to achieve highly efficient, environmentally stable, and commercially acceptable IOSCs. Through such efforts, the maximum power conversion efficiencies (PCEs) of IOSCs have surpassed 35%. In this regard, the transition from a fullerene to non-fullerene acceptor (NFA) is a useful strategy for enhancing the PCEs of IOSCs by allowing adjustment of the energy levels for compatibility with the indoor light spectrum and by improving photon absorption in the visible range, thereby boosting photocurrent generation and enhancing V OC. NFA-based indoor organic photovoltaic systems have recently drawn interest from the scholarly community. To compete with the standard batteries used in the Internet of Things devices, additional research is needed to enhance several characteristics, including manufacturing costs and device longevity, which must maintain at least 80% of their initial PCEs for more than 10 years. Further development in this field can greatly benefit from a thorough and comprehensive review on this field. Hence, this review explores recent advances in IOSCs systems based on NFAs. First, we explain several methods used to create extremely effective IOSCs, IOSCs based on fullerene acceptors are next reviewed and discussed. The disadvantages of using fullerene acceptors in IOSCs are noted. Then, we introduce NFAs and explore existing research on the subject. Finally, we discuss the commercial potential of NFA-based IOSCs and their future outlook.

“…Recently, a few studies tried to assess the effects of different operation parameters on indoor OPVs and their operational mechanism through optical modulation via finite difference time‐domain (FDTD)‐based simulation. [ 49,62,63,82,85–92 ] The optical simulation enables one to find concentrated intensity of light within the active layer, and optimize light absorption by using diverse combinations of common layers and electrodes in different conventional and inverted configurations. Such calculation has led to rationally designed high‐performance photovoltaics in experiments.…”

Recently, the growing popularity of indoor electronic devices has led to considerable attention on ambient energy harvesting systems. In particular, the incorporation of electronic products that harness the Internet of Things (IoT) services has spurred interest in semipermanent indoor power generation systems, owing to their numerous sensor nodes. [1][2][3][4][5] Ambient energies such as light and heat and the conversion systems to turn them into electricity have been vigorously investigated for practical applications. Among them, indoor light energy and photovoltaic (PV) systems have shown potential for harvesting ambient energy, considering the high accessibility of the pertinent energy sources as well as the excellent power conversion capabilities of the PV system. [6][7][8][9][10][11][12] PV systems could incorporate different types of light-absorbing materials such as silicon, gallium arsenide, and organics. Organic photovoltaics (OPVs) is most suited for indoor energy harvesters, since their unique optical properties (such as high absorption coefficient and bandgap tunability) and other features (such as superior mechanical flexibility and diverse color options) could well match the indoor light conditions/environments characterized by low light intensity, varying output spectra, and aesthetic considerations. [13][14][15][16][17][18][19] Many studies tried to enhance the performance of OPVs under altered light conditions as opposed to outdoor conditions (1 sun) (more in detail will be discussed later). [20][21][22][23][24] As a result, substantial progress has been made, with the power conversion efficiency (PCE) up to 28% [25] with a 1000 lx fluorescent (FL) lamp and 30.8% with a 1650 lx light emitting diode (LED). [4] These PCE values correspond to ≈160 µW cm −2 in output power density, which is large enough to operate certain indoor electronic devices such as smoke detectors (6 µW) and occupation motion detectors (28 µW). However, these values are far below the theoretical limits of 45.7% for the FL lamp and 58.4% for the LED. [26] Thus, there remains significant room for improvement.Compared to 1 sun illumination commonly considered for outdoor PVs, the indoor environment is characterized by much lower light intensities and completely different output spectra. Therefore, realization of efficient OPVs under indoor Recently, indoor organic photovoltaics (OPVs) has attracted substantial research attention, due to the emergence of self-powered electronic devices for Internet-of-Things (IoT) applications. This progress report discusses recent developments in indoor OPVs, focusing on the strategic role of synergistic parasitic resistance in suppressing the leakage current to achieve high indoor efficiencies. Moreover, an underexplored area is presented, namely the impact of optical modulation on enhancing light absorption in indoor OPVs. First, the main advances in material design for indoor OPVs are briefly presented. This is followed by detailed discussions of the crucial strategies, including interfacial e...

“…In this article, we have demonstrated the optimization of an organic solar cell through the optimization of the optical spacer layers. Traditionally, finite difference time domain (FDTD) method was used to simulate the ideal short circuit current density (J sc ) of the solar cell through the Lumerical, FDTD solutions software [12,13]. Parameter sweep or brute-force method was used to vary the thickness of the optical spacer layers of the solar cell.…”

Conventional solar cells are predominately designed similar to a stacked structure. Optimizing the layer thicknesses in this stack structure is crucial to extract the best efficiency of the solar cell. The commonplace method used in optimization simulations, such as for optimizing the optical spacer layers' thicknesses, is the parameter sweep. Our experiments show that the introduction of genetic algorithm based method results in a significantly faster and accurate search method when compared to brute-force parameter sweep method in both single and multi-layer optimization. While other sweep methods can also outperform the brute-force method, they do not consistently exhibit 100% accuracy in the optimized results like our genetic algorithm. Our best case scenario was observed to utilize 57.9% less simulations than brute-force method. 1
