“…Many studies just focus on developing neutral color semitransparent OSCs, but such devices are difficultly applied to esthetic and decorative products that require vivid colors. The emergence of colorful semitransparent OSCs broke this limitation 101,102 . Generally, the light‐absorbing material determines the color of the semitransparent device, which brings the challenge in material synthesis for specific color display.…”

Due to their potentials in light-weight, flexible, and semitransparent devices, organic photovoltaics are of great significance in the field of renewable energy. However, the narrow intrinsic absorption spectrum of organic materials hinders the full utilization of solar energy. To fabricate a highly efficient opaque solar cell, it is greatly necessary to modify the optical properties of the device to improve light absorption. In addition, the growing interest in building-integrated photovoltaics drives the development of semitransparent devices. The preparation of semitransparent solar cells with excellent performance imposes high requirements on the high efficiency and appropriate visible light transmittance of effective optical management. In this review, the recent research progress of optical management in organic photovoltaics is reviewed, including the design of light-absorbing materials, the modification of different layers, adding a lighttrapping structure, and changing the light absorption capabilities of specific materials, so as to provide strategies of how to improve the performance of organic photovoltaic devices and present the prospect of the area.

Semi‐transparent organic solar cells (ST‐OSCs) have revolutionized the field of photovoltaics (PVs) due to their unique abilities, such as transparency and color tunability, and have transformed normal power‐harvesting OSC devices into multifunctional devices, such as building‐integrated photovoltaics, agrivoltaics, floating photovoltaics, and wearable electronics. Very recently, ST‐OSCs have seen remarkable progress, with a rapid increase in power conversion efficiency from below 7% to 12–14%, with an average visible transparency of 9–25%, especially due to the use of low bandgap semiconductors including polymer donors and non‐fullerene acceptors that exhibit absorption in the near‐infrared region as photoabsorbent materials. From this perspective, the latest developments in ST‐OSCs stemming from the innovations in photovoltaic materials that delivered multifunctional ST‐OSCs with top‐of‐the‐line power conversion efficiencies are discussed to shed light on the structure‐property relationship between molecular design and current challenges in this cutting‐edge research field. Finally, personal perspectives, including research directions for the future use of ST‐OSCs in multifunctional applications, are also proposed.

“…As the main application field of semi‐transparent solar cells, building‐integrated photovoltaics particularly rely on visual parameters such as brightness and average visible transmittance (AVT) to improve visual aesthetics. [ 70 ] Semi‐transparent perovskite solar cells (ST‐PSCs) with an adjustable band gap and higher efficiency is a promising candidate. In order to ensure proper optical transparency, the thickness of the perovskite layer and the design of the microstructure have been proved to be effective methods.…”

In recent years, the development of perovskite solar cells (PSCs) is advancing along the way, and the efficiency is comparable to traditional silicon‐based solar cells. However, as crucial factors in the road to commercialization, stability and upscaling manufacture have not been fully investigated yet. To solve these problems, the exploration of charge transport layer (CTL) is clearly imminent, which is critical to the stability of PSCs. Among them, inorganic metal oxides have better stability than organic CTL. Particularly, the atomic layer deposition (ALD) process can fabricate dense and scalable metal oxides based on the self‐limiting surface reaction. This perspective focuses on the recent progress of ALD‐grown metal oxides in PSCs: both of electron and hole transport layer; connection layer in tandem architectures; application in semi‐transparent perovskite solar cells (ST‐PSCs); prospective of commercialization feasibility of the ALD‐grown metal oxides in ST‐PSCs.
