For polymer solar cells, Zou et al. reported a narrow-band acceptor Y6 and blended it with PM6 then achieved a PCE of 15.7% under the highest occupied molecular orbital (HOMO) energy level offset (Δ EH = EHOMO (D) – EHOMO (A)) of 0.25 eV .
2. Theoretical background Solar cells harness energy from sunlight, which comprises photons distributed across various wavelengths influenced by factors such as location, time, and month (Green, 2012a). The AM1.5 G spectrum, which adheres to the ASTM standard G173 (Fig. 3h), encompasses both direct and diffuse light components (Green, 2012b).
The FF of solar cells is positively dependent on Δ HOMO and τCS. Fill factor (FF) is an important parameter governing the power conversion efficiency (PCE) in non-fullerene organic solar cells (NF–OSCs), which however is less studied than the other two parameters (short-circuit current Jsc and open-circuit voltage oc ).
The power conversion efficiency of a solar cell is a parameter that quantifies the proportion of incident power converted into electricity. The Shockley-Queisser (SQ) model sets an upper limit on the conversion efficiency for a single-gap cell.
The amount of solar radiation energy reflected by the device can have a substantial influence on this loss, which affects the efficiency of the solar cell as a whole.
