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.

“…Organic solar cells (OSCs) have attracted tremendous attention in the past decades due to their fascinating advantages, such as lightweight, flexibility, large-area fabrication, and low-cost roll-to-roll processability. − The improvement in power conversion efficiency (PCE) up to 18% for binary single junction OSCs can be attributed to the advances of nonfullerene acceptors (NFAs) featuring high light-harvesting capacity, facilely adjustable energy levels, and absorption spectrum. − Nowadays, the mainstream of small-molecular acceptors (SMAs) structures of NFAs is the A–D–A (acceptor–donor–acceptor) framework. , Among them, the state-of-the-art SMA Y6, − which exhibits excellent performance and can match well with numerous donors, has promoted the power conversion efficiencies of OSCs rapidly in recent years.…”

Advances of small-molecular acceptors (SMAs) recently have motivated the development of high-performance organic solar cells (OSCs). The SMAs featuring A–D–C–D–A framework have attracted numerous attention due to their facile tunability on chemical structures and in commercial synthesis. In this work, dithienobenzothiadiazol (DTBT) was utilized as the center (C) unit of A–D–C–D–A SMAs and three corresponding SMAs named DTBCIC-Cl, DTBCIC-F, and DTBCIC-H were synthesized by altering the terminal groups. The variation of terminal groups endowed SMAs with different performances, including optical absorbance, energy levels, and molecular packing, etc. In comparison to DTBCIC-H, DTBCIC-Cl and DTBCIC-F obtained by halogenation showed red-shift absorption, well matched energy levels with the polymer donor PM6, as well as closer molecular packing, rendering the blend films based on PM6:DTBCIC-Cl and PM6:DTBCIC-F wide absorption and improved morphology. High power conversion efficiency of 12.71% was thus obtained for OSCs based on DTBCIC-Cl. The results prove that optimization of SMAs via altering terminal groups provides a promising design strategy to obtain high-performance A–D–C–D–A SMAs.

“…The overlap of the excitation spectrum (green curve) and the strong absorption spectrum of solar cell device (red curve) illustrate that the K 2 HfSiO 5 :Eu 2+ EDS layer has the ability to make the UV light from the sun light be effectively absorbed by CsPbI 3 solar cells due to the down-conversion effect. 57 The CsPbI 3 solar cells coated with the EDS layer have been packaged as shown in the schematic diagram in Fig. 9(d) according to the above analysis.…”
