Solar cells currently used are silicon based because they have higher efficiency than cells from other materials, but the manufacturing cost is high. Though, cheaper cells can be fabricated using organic materials because it solution processable, the efficiency is very low. Hybrid solar cells have improved the efficiency of organic solar cells. Hybrid solar cells with ZnO nanorods as the inorganic and P3HT (poly 3-hexylthiophene) and PCBM ((6, 6)-phenyl C61 butyric acid methyl ester) as the active layer reported in literature is usually prepared by spin coating. The major drawback of using spin coating technique is that large area fabrication is not possible and material wastage makes this technique uneconomical. Large scale production is feasible if these cells can be prepared by spray coating. Here we will discuss the fabrication and characterization of hybrid solar cells by spray coating technique.
