Design and fabrication of a semi-transparent solar cell considering the effect of the layer thickness of MoO 3 /Ag/MoO 3 transparent top contact on optical and electrical properties

We conducted the present study to design and manufacture a semi-transparent organic solar cell (ST-OSC). First, we formed a transparent top contact as MoO 3 /Ag/MoO 3 in a dielectric/metal/dielectric (DMD) structure. We performed the production of an FTO/ZnO/P3HT:PCBM/MoO 3 /Ag/MoO 3 ST-OSC by integrating MoO 3 /Ag/MoO 3 (10/ d_m / d_od nm) instead of an Ag electrode in an opaque FTO/ZnO/P3HT:PCBM/MoO 3 /Ag (–/40/130/10/100 nm) OSC, after theoretically achieving optimal values of optical and electrical parameters depending on Ag layer thickness. The transparency decreased with the increase of d_m values for current DMD. Meanwhile, maximum transmittance and average visible transmittance (AVT) indicated the maximum values of over 92
