“…Cao et al reported a roll-to-roll compatible semitransparent OSC with PTB7:PC 71 BM blends sandwiched between a bottom 1DPCs and a top PH1000 PEDOT:PSS layer (see Figure 13b). [165] Owing to the increase of the integrated photon flux density in the photoactive layer by 1DPCs, the PCE of 5.2% and J sc of 12.25 mA cm −2 were achieved, which were increased by 37% and 38%, respectively, when compared with those of the semitransparent devices without using 1DPCs. Very recently, Li et al [166] reported inverted semitransparent OSCs with Au/Ag TTE and fine-tuned dielectric mirrors (DMs) (see Figure 13c).…”

Flexible and semitransparent organic solar cells (OSCs) have been regarded as the most promising photovoltaic devices for the application of OSCs in wearable energy resources and building‐integrated photovoltaics. Therefore, the flexible and semitransparent OSCs have developed rapidly in recent years through the synergistic efforts in developing novel flexible bottom or top transparent electrodes, designing and synthesizing high performance photoactive layer and low temperature processed electrode buffer layer materials, and device architecture engineering. To date, the highest power conversion efficiencies have reached over 10% of the flexible OSCs and 7.7% with average visible transmittance of 37% for the semitransparent OSCs. Here, a comprehensive overview of recent research progresses and perspectives on the related materials and devices of the flexible and semitransparent OSCs is provided.

“…Since the slow‐photon effect is induced by light propagating in a PC structure and since it aims to enhance light harvesting by the very same structure, it could be applied in all light‐related applications including photoreactions, optical sensors and photovoltaics . Moreover, which photonic bandgap edge (blue or red) is more efficient in the slow‐photon effect still remains a controversial question.…”

Solar light is widely recognized as one of the most valuable renewable energy sources for the future. However, the development of solar-energy technologies is severely hindered by poor energy-conversion efficiencies due to low optical-absorption coefficients and low quantum-conversion yield of current-generation materials. Huge efforts have been devoted to investigating new strategies to improve the utilization of solar energy. Different chemical and physical strategies have been used to extend the spectral range or increase the conversion efficiency of materials, leading to very promising results. However, these methods have now begun to reach their limits. What is therefore the next big concept that could efficiently be used to enhance light harvesting? Despite its discovery many years ago, with the potential for becoming a powerful tool for enhanced light harvesting, the slow-photon effect, a manifestation of light-propagation control due to photonic structures, has largely been overlooked. This review presents theoretical as well as experimental progress on this effect, revealing that the photoreactivity of materials can be dramatically enhanced by exploiting slow photons. It is predicted that successful implementation of this strategy may open a very promising avenue for a broad spectrum of light-energy-conversion technologies.

“…Similarly, Shen et al used 1DPC to simultaneously improve PCE and the color rendering index (CRI) of STOSC. Optical simulation was performed to provide direct evidence that the PCE enhancement was the result of the enhanced light absorption . Among these works, optical simulation was usually used to design device structure or explain improvements of device performance.…”

Semitransparent organic solar cells (STOSCs) show great potential for application as power generating windows for buildings. The power conversion efficiency (PCE) and the average visible transmittance (AVT) are both important parameters with which to evaluate the overall performance of STOSCs. However, it is very challenging to simultaneously improve these two performance parameters because they are intrinsically contradictory to each other. In this work, the optical and photovoltaic properties of STOSCs are investigated based on two model samples including PTB7‐Th:PC61BM and PTB7‐Th:PC71BM by systematically tuning their device structures. By combining optical modeling and experimental results, a full optical analysis is provided for the STOSCs with details on photon harvesting, optical losses, transmission properties, energy distribution spectrum, electric field intensity distribution, and photon absorption rate distribution within the devices. Defined as the sum of the external quantum efficiency and the transmittance, the term “quantum utilization efficiency” is used as a subjective parameter to describe the light energy use in the semitransparent devices, which provides an alternative angle for analyzing STOSCs.
