- Abstract
- We reported the morphological characteristics of SiNWs-incorporated pyramid-textured Si surface, and analyzed its photovoltaic performance in comparison with both pyramid-textured and planar Si solar cells. The power conversion efficiencies (PCEs) were determined to be approximately 6.4%, 9.5%, and 11.5%, respectively corresponding to planar, pyramid-textured, and SiNWs-incorporated pyramid-textured heterojunction Si solar cells coated with PEDOT: PSS layers. Furthermore, the SiNWs-incorporated pyramid-textured solar cell showed excellent photovoltaic performance with short current density (J(SC)) of 28.5 mA/cm(2), open-circuit voltage (V-OC) of 0.55 V, and fill factor (FF) of 71% under AM 1.5G illumination. This result suggested that the PEDOT: PSS-coated SiNWs-incorporated pyramid-textured heterojunction Si solar cell exhibits a remarkable suppression in reflectance at short wavelength range, which in turn leads to the highest photocurrent and PCE.
