“…[ 7,8 ] E b for organic materials is usually in the range of 0.1–1.0 eV, [ 9 ] which is much higher than those for perovskite and inorganic semiconductors. [ 10 ] The high E b leads to large energy loss and severe geminate recombination for OSCs. [ 9 ] Furthermore, because of the large E b and short exciton lifetime, it is necessary to employ a BHJ structure with bicontinuous interpenetrating networks with nanoscale phase separation to facilitate exciton dissociation with the energy level difference, leading to morphology control issues.…”

The past three years have witnessed the power conversion efficiency (PCE) of organic solar cells (OSCs) rocketing to over 18%, due to outstanding advantages of non‐fullerene acceptors (NFAs). However, large exciton binding energy (E b) caused by strong Coulombic force is still one of the main limiting factors for high‐performance OSCs. Thus, it is critical to reduce the E b for further enhancement of device performance. Many strategies have been developed to reduce the E b of organic materials previously. In this perspective, the calculation methods for E b and the relationship between E b and voltage loss (V loss) are discussed. Then, the effects of the properties of small‐molecule acceptors on E b from the perspectives of fused‐ring donor cores, end groups, side chains, and molecular packing are discussed. Finally, the potential directions for reducing E b and pointing out the trade‐off between E b and bandgaps/miscibility are put forward. It is hoped that this perspective could provide a new thinking of a molecular design for the breakthrough of OSCs.

Perovskite (PSK) materials have received extensive attention because of their potential use as the active layer of different applications, including capacitors, sensors and detectors, memories, catalysts, fuel cells, and optoelectronic devices (solar cell and light‐emitting diode). Herein, the past, current, and future status of these applications are focused on. The state of each application is investigated using diverse technology indicators. It reveals that among all the applications, the optoelectronic application is the youngest one and has not yet reached the technology growth stage though it possesses most of the recently published patents. Using a technology investment potential evaluation method, the most potent area for investment is explored, indicating that detectors and sensors are the ones with the biggest investment potentials. Remarkably, PSK solar cell dedicates more than 70% of the patents to itself with the highest predicted efficiency of 30% that will be achieved in 2023 according to the curve fitting method and in 2030 according to the S‐curve method. As a perspective, currently, the highest efficiency and stability are achieved for small‐sized PSK solar cells, it is expected that they would be commercialized in electronic equipment applications first, and after overcoming the challenges, large‐scale modules would enter the markets.

, 85 pages Two random terpolymers, PBTS and PBTSe were designed and synthesized successfully as the donor units for polymer organic solar cell. Desired terpolymers contain alkoxy-benzodithiophene as an electron rich unit and Noctylthieno[3,4,c]pyrrole-4,6-dione (TPD) as the electron deficient group. Furthermore, thiophene and selenophene π bridges were introduced to benzotriazole unit as the acceptor moieties into copolymer backbone. The properties of synthesized terpolymers solar cell device were investigated by optical, electrochemical, spectroelectrochemical, kinetic studies. One of the terpolymer, PBTS showed an optical band gap of 1.84 eV with highest occupied molecular orbital (HOMO) energy level of-5.29 eV, open circuit voltage of 0.64 V, short circuit current density of 10.57 mA/cm 2 and fill factor of 63.5%. The power conversion efficiency of bulk heterojunction solar cell device based on PBTS: PC71BM blend film was recorded as 4.30% by introducing 1% 1, 8 diiodooctane (DIO) as the solution process additive. The second terpolymer, PBTSe exhibited lower optical band gap of 1.78 eV with a HOMO energy level of-5.27 eV, open circuit voltage of 0.69 V, short circuit current density of 11.88 mA/cm 2 and fill factor of 62.7%. The power conversion efficiency of bulk heterojunction solar cell device based on PBTS: PC71BM blend film was vi recorded as 5.15% by introducing 3% diphenyl ether (DPE) as the solution process additive.
