Abstract Non-fullerene acceptors have recently ignited extensive interest in organic solar cells (OSCs) because of their higher power conversion efficiency (PCE) than fullerene counterparts. Though the effect solvent additive 1, 8-diiodooctane (DIO) has been studied extensively for fullerene-based acceptor OSCs, not much is known non-fullerene OSCs. In our work, bulk-heterojunction (BHJ) OSCs were fabricated by blending (PC 71 BM) and (ITIC IEICO-4F) with low bandgap polymer donor (PTB7-Th). Further, effects on nanomorphology, performance, photostability devices investigated. absence DIO, IEICO-4F showed PCE PTB7-Th: ITIC PC BM BHJ-OSCs due to absorption near infrared along high J sc . The addition DIO increased improved miscibility molecules, donor/acceptor interface area, phase separation. However, adversely affected overall device performance BHJ-OSCs. Furthermore, processed less photostable exhibited faster degradation photoacid additive.

OLED OLSD have same geometry simple structure any interlayers: glass/ITO/PEDOT:PSS/(active layer)/Ca/Al; OPC formed by which adhere tightly to each other. Despite its structure, showed current transfer ratio 0.13%, good linearity, dynamic performance: three-decibel cutoff frequency 170 kHz response times step change in at input 2 μs. Compared most devices similar performance parameters, where complex structures additional interlayers between layers electrodes need apply voltage receiver, design our reduces number fabrication steps greatly simplifies device process.

Abstract Organic photovoltaics (OPVs) and organic photodetectors (OPDs), which use conjugated polymers molecules as photoactive materials, hold significant promise for energy harvesting sensing applications due to their customizable optoelectronic properties, potential mechanical flexibility, compatibility with low‐cost, high‐throughput manufacturing. However, OPV OPD research date has typically relied on device fabrication in controlled environments (e.g., glove boxes filled inert gases) vacuum‐deposited (rather than solution‐processed) electrodes, limiting scalability increasing manufacturing complexity cost. This review explores these challenges by surveying the development of ambient‐air‐processed, solution‐based (APSB) OPVs OPDs, not only solution‐processed electrodes but are also entirely fabricated under ambient conditions. Various solution processing techniques, performance APSB OPDs comprehensively examined, offering insights future advance technologies toward ultra‐low‐cost optoelectronics harvesting.
