“…Besides serving as power units, MBs can also act as energy storage devices that store energy from external energy harvesters, e.g., solar cells, nanogenerators, or direct power supplies. [66][67][68] Directly harvesting and utilizing power from solar energy is renewable and environmentally friendly. To this end, a self-powering wristband system by integrating flexible Zn-ion MB with perovskite solar cells was demonstrated (Figure 6b).…”

The rise of wearable and implantable microelectronics calls for the corresponding high‐performance micropower sources. Rechargeable micro‐batteries (MBs) are considered the most promising candidate due to their high energy density and stable voltage output. To date, various MBs with different configurations have been designed to meet the ever‐growing high energy consumption requirements of microelectronic devices. Therefore, it is very urgent to summarize the current challenges of MBs and discuss solutions for future research. In this perspective, a comprehensive overview and insights on rechargeable MBs are carefully presented with an emphasis on the design of various configurations. The representative preparation methods and application scenarios of various MBs have been summarized. The challenges and future perspectives are also discussed to provide insights into the forward‐looking research and potential directions of this promising field.

“…By stacking two or more sub‐cells with complementary absorption range, the tandem devices can harvest high and low energy photons in the separated sub‐cells providing a potential route to diminish the thermalization loss of photonic energy and overcome the Shockley–Queisser (S‐Q) limit of single‐junction devices. [ 73 ] Despite the hustle of multi‐layer deposition to produce the tandem OSCs, it was found to be more convenient to realize high performance tandem OSCs without limitation of material choices and complexity of morphology control involved in multi‐blend OSCs.…”

Organic solar cells (OSCs) have attracted wide research interests in the past decades. In recent years, our group mainly focused on the new photovoltaic materials design and device engineering technologies for highly efficient OSCs. This account mainly summarizes our recent studies on the structural design of wide bandgap (WBG) polymers and their morphology control as well as applications in OSCs. Additionally, we introduce our work on binary and ternary blend devices and tandem solar cells containing these materials. What is the most favorite and original chemistry developed in your research group? We focus on design and synthesis of high‐performance organic semiconductors for photovoltaic applications. Our interests are exploring the relationships between the conjugated molecular structures and their photovoltaic properties. How do you get into this specific field? Could you please share some experiences with our readers? When I was in Singapore and USA as a postdoctoral research fellow, I found that the energy crisis and environmental pollution were becoming more and more serious. I believed that organic solar cell (OSC) would be sprung up in the near future and I needed to do something about it. Therefore, I begun to follow with interest the OSCs in 2006 and got into this field in 2007. How do you supervise your students? I am in pursuit of development on self‐thinking abilities of my students.

Comprehensive Summary Researchers investigated the organic optoelectronic materials and facilitated their development in organic light‐emitting diodes (OLEDs), chemo‐ and biosensors, organic solar cells, data storage, and anticounterfeiting devices. Atoms make up molecules through chemical bonds, and molecular aggregates are formed through weak intermolecular interactions. The opto‐electronic performance of these materials depends on not only the properties of the well‐designed molecules with specific function groups, but also their aggregate states. The molecular aggregates in the form of nanoparticles can be applied in biological imaging, and films can be applied to photovoltaic and photodeformable devices, in which, the alignment of optoelectronic molecules can be either an ordered crystalline or an amorphous state. Generally, the crystalline materials could be deeply investigated by single crystal/powder X‐ray diffraction analysis, which could provide the accurate information about molecular conformations, interactions and packing characteristics. It afforded a convenient way to investigate the possible relationship between molecular aggregates and opto‐electronic properties. Among various opto‐electronic materials, organic room temperature phosphorescence (RTP) materials exhibit the extremely sensitive luminescence property to molecular aggregates, even the dynamic properties can be detected by the tiny change of molecular aggregates. Thus, we selected the organic RTP emission as the output information of molecular aggregates, and afforded typical examples to find the possible relation between RTP effect and molecular packing. Accordingly, molecular packing can be adjusted by the external force as light, mechanical force, temperature, electric field, and so on, as well as the molecular structures as the building blocks, and the systematic investigation in the dynamic and static aggregation structures is of great value to the design of various optoelectronic materials. This review discusses the relationship among molecular structures, aggregation behaviors and corresponding optoelectronic properties by a comprehensive summary of recent research in our group, and the concept of molecular uniting set identified characteristic (MUSIC) is afforded. What is the most favorite and original chemistry developed in your research group? The concept of “Suitable Isolation Group” for molecular design of organic second‐order nonlinear optical (NLO) materials. Molecular packing is highlighted as the key point to opto‐electronic materials, which are partially summarized in this mini review to present “MUSIC” in the molecular world. How do you supervise your students? Discussions. We do discussions for science, interests and other topics related to research together, through which to solve the encountered problems. What is the most important personality for scientific research? Curiosity, desire to advance, persistence, sense of urgency, and team spirit. What are your hobbies? What's your favorite book(s)?? Listening to music...
