Abstract The quality of perovskite films plays a fundamental role in determining the performance solar cells (PSCs). It is widely recognized that achieving high crystalline and minimizing defect density are essential. In this study, utilization multifunctional additive 5‐ammonium acid (5‐AVA) to improve morphology proposed. ‐NH 2 ‐COOH groups 5‐AVA enable effective coordination with Pb ions organic perovskite, resulting suppression formation reduction non‐radiative recombination losses....
Perovskite materials have demonstrated excellent performance in the field of solar cells, and device efficiency has already exceeded 25%. However, to date, perovskite cells (PSCs) not been able achieve large‐scale production. The biggest obstacle commercializing PSCs is stability problem that widely criticized since their inception. In last 5 years, emergence 2D/3D perovskites provided a new way solve this problem. review, representative work on summarized, focusing how structures can...
Despite advances in the efficiency of inverted perovskite solar cells using self-assembled monolayers (SAMs), challenges persist both and stability due to issues at bottom interface within...
Charge carrier transport in the active layer and charge extraction at electrode have significant impact on performance of solar cells.
Cathode buffer layer interface modification is a commonly used strategy to prepare high‐efficient organic solar cells (OSCs). Nonfullerene OSCs based on PM7:IT‐4F are prepared and modified with poly[(9,9‐bis(3′‐( N , ‐dimethylamino)propyl)‐2,7‐fluorene)‐alt‐2,7‐(9,9‐dioctylfluorene)] (PFN)‐Br cathode layer. The introduction of the PFN‐Br obviously boosts photovoltaic performance PM7:IT‐4F‐based OSCs, however, stability PFN‐Br‐modified device shows serious degradation. By excluding influence...
Active layer morphology optimization is a commonly used effective strategy to improve the photovoltaic performance of organic solar cells (OSCs). In this study, halogen-free solvent, o-xylene (OX), was as host and dichloromethane (DCM) guest solvent regulate active enhance power conversion efficiency (PCE) PM7:IT-4F nonfullerene OSCs. With introduction DCM into OX, crystallization improved, enlarged domain size provides favorable channel for charge transport. The improved transport...
Bilayer interdiffusion heterojunction with the structure of a donor-rich region near anode and an acceptor-rich cathode could weaken energy-level barrier between active layer electrode improve performance organic solar cells. In this study, poly(3-hexylthiophene)/[6:6]-phenyl-C61-butyric acid bilayer cells were prepared using orthogonal solvent method charge transport extraction characteristics investigated in detail. The transient photovoltage/transient photocurrent measurements showed that...
Introducing a cathode modification layer is an effective method to obtaining highly efficient organic solar cells (OSCs) and improving their stability. Herein, we innovatively introduced double (SnO2/ZnO) into non-fullerene OSCs based on PM7:IT-4F explored the mechanisms. The effects of SnO2/ZnO film charge carriers transfer in are studied via variety electrical testing methods including Photo-CELIV measurements. As result, buffer with low recombination rate high carrier mobility could be...
Adding a solvent additive into the active layer is simple and effective strategy to improve morphology performance of bulk heterojunction organic solar cells (OSCs). Herein, poly[(2,6‐(4,8‐bis(5‐(2‐ethylhexyl‐3‐chloro)thiophen‐2‐yl)‐benzo[1,2‐b:4,5‐b′]dithiophene))‐alt‐(5,5‐(1′,3′‐di‐2‐thienyl‐5′,7′‐bis(2‐ethylhexyl)benzo[1′,2′‐c:4′,5′‐c′]dithiophene‐4,8‐dione)] (PM7) used as donor [6,6]‐phenyl‐C71‐butyric acid methyl ester (PC 71 BM) acceptor, 1,8‐diiodooctane (DIO) 1‐chloronthalene (CN)...
