6 FAQs about [Bulk heterojunction organic photovoltaic cells]
Are organic solar cells based on bulk heterojunction better?
In the last few years, the performance of organic solar cells (OSCs) based on bulk heterojunction (BHJ) structure has remarkably improved. However, for a large scale roll to roll (R2R) manufacturing of this technology and precise device fabrication, further improvements are critical.
Does bulk heterojunction improve photovoltaic performance?
The development of the bulk heterojunction (BHJ) has significantly overcome these issues, resulting in dramatic improvements in organic photovoltaic performance, now exceeding 18% power conversion efficiencies.
Can kinetically bulk heterojunction film morphology be degraded in organic solar cells?
Degradation of kinetically bulk heterojunction film morphology in organic solar cells is a grand challenge for their practical application. Here, the authors design and synthesise multicomponent photoactive material by facile one-pot polymerization and achieve efficiency of 11.8% and T80 of 1000 h.
Can graded bulk-heterojunction surpass classical BHJ in organic solar cells?
Graded bulk-heterojunction (G-BHJ) with well-defined vertical phase separation has potential to surpass classical BHJ in organic solar cells (OSCs). In this work, an effective G-BHJ strategy via nonhalogenated solvent sequential deposition is demonstrated using nonfullerene acceptor (NFA) OSCs.
