Frequently, computational estimates of the PCE employ the widely used Scharber equation,6 which predicts the PCE of a given organic solar cell architecture from only a few key parameters, all of which can be determined by application of quantum chemical methods. 2021 The Authors. Published by American Chemical Society.
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.
The various parts of OPV cells are discussed, and their performance, efficiency, and electrical characteristics are reviewed. A detailed SWOT analysis is conducted, identifying promising strengths and opportunities, as well as challenges and threats to the technology.
Context & scale. Because of the vigorous design and development of organic photovoltaic materials, power conversion efficiency (PCE) is improved rapidly, approaching the threshold of 20%. However, the high costs and intrinsic operational instability of organic solar cells (OSCs) have slowed down its commercialization.
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].
28 Φεβ 2024 · A well‐mixed phase formed by two compatible non‐fullerene acceptors enables ternary organic solar cells with efficiency over 18.6%. Adv. Mater. 33 , 2101733 (2021).
