The performance of OPV (Organic photo voltaic) or OSC’s (Organic solar cell) devices are depend on mobality of free electron and holes generated in organic active layer. The interface between donar and acceptor layer are active site for exciton dissociation. The number of free electron and holes formed after dissociation of exciton are major contributor of Jsc. We also study the effect of roughness of Phthalocyanine (small molecule organic material) as donar layer with C60 as acceptor layer in bilayer OPV device. We have studied the AFM and XRD of copper phthalocyanine (CuPc), zinc phthalocyanine (ZnPc) and Metal free phthalocyanine (Hydrogen Phthalocyanine – H2Pc). We found that the selections of active layer material in OPV device are such that the roughness level of both materials forms maximum interface area between donar and acceptor.

A study was carried to observe the effect of green manure decomposed by distillery effluent on Cicer arietinum L.cv. 256. The study revealed that 50% concentration of treated distillery effluent with green leaf manure (Sesbania aculeata) has promotory effect than 100% concentration and only green leaf manure over control. The germination percent, seedling growth, germination relative index, phytomass and vigour index were found higher in 50% concentration of distillery effluent with green leaf manure. As green manure envisages a comprehensive management approach to improve the health and underlying productivity of the soil. Therefore, it is recommended that distillery effluent has appreciable amount of plant nutrients which can be assimilated into soil for growth after proper dilution and treatment.
