In this paper, a Al/ZnO/a-Si/polymer solar cell is fabricated by using the sputtering
technique. The current–voltage characteristic curve indicates that the cell efficiency
increased from 0.05453% to 0.484% for ZnO/Si/poly(3-hexylthiophene) as the Si film
thickness increased. When the cell was fabricated using ZnO/Si/polyvinyl chloride and
ZnO/Si/paraphenylene vinylene, the efficiencies increased from 0.505% to 2.793% and from
1.6% to 2.934%, respectively, as the Si film thickness increased.
Keywords: polymer, solar cell, ZnO/Si/PVC, ZnO/Si /P3HT, and ZnO/Si/PPV
1. Introduction
Glass or metal sheets are commonly used as substrate materials for amorphous silicon Abstract— Photovoltaic cells provide an additional method
of acquiring energy, converting sunlight directly into electricity
through the use of semiconductors. Effective photovoltaic
implementation is reviewed, focusing on semiconductor
properties and overall photovoltaic system configuration.[1]
