Web1 de fev. de 2024 · We present evidence that bandgap narrowing at the heterointerface may be a major cause of the large open circuit voltage deficit of Cu2ZnSnS4/CdS solar cells. Bandgap narrowing is caused by surface states that extend the Cu2ZnSnS4 valence band into the forbidden gap. Web23 de jan. de 2024 · Most semitransparent organic solar cells (ST-OSCs) show a low open-circuit voltage (V OC) because of the inherent narrow band-gap of the active layer materials, which is proven to be a key limitation for the improvement of the device performance.To obtain a high V OC, wide-band gap polymer donors, such as PM6 are …
