23 ώρες πριν · Organic solar cells (OSCs) are perceived as one of the most promising next-generation sustainable energy technologies due to their unique features like light weight, flexibility, transparency, low cost, and easy processing (1–3).To date, the power conversion efficiencies (PCEs) of the rigid and flexible single-junction OSCs exceed 20 and 18%, respectively (4–9).
20 Ιουλ 2022 · Organic solar cells (OSCs) based on polymer donor and non-fullerene acceptor achieve power conversion efficiency (PCE) more than 19% but their poor absorption below 550 nm restricts the harvesting of high-energy photons.
Our efficiency of 15.24% constitutes 1.79% absolute increase for cells ≥ 1 cm 2, and we obtained the following key parameters: JSC = 24.24 mAcm −2, VOC = 846.7 mV, and fill factor (FF) = 74.25%.
21 Αυγ 2024 · Key points. Development of new materials and optimization of morphology has led to improved performance of organic photovoltaics and will enable commercial application.
3 ημέρες πριν · Although the PCE — defined as the ratio of electrical power delivered by a solar cell to the incident solar energy — of organic solar cells currently lags behind that of inorganic cells ...
19 Ιαν 2022 · 1 Introduction. Development in the field of excitonic solar cells (ESC), i.e., organic photovoltaic (OPV), perovskite solar cells (PSC) etc., has been increasing alarmingly at a very fast pace due to the urgent need of renewable source of energy [1, 2].
5 Μαΐ 2022 · Abstract. In organic photovoltaics, morphological control of donor and acceptor domains on the nanoscale is the key for enabling efficient exciton diffusion and dissociation, carrier transport...
