Dye-sensitized solar c.lls（DSc.） have attrac.ed a great deal of attention due to their low-c.st and high power c.nversion effic.enc.es. They usually utilize an interc.nnec.ed nanopartic.e layer of TiO2 as the elec.ron transport medium. From the fundamental point of view, faster mobility of elec.rons in Zn O is expec.ed to c.ntribute to better performanc. in DSc. than TiO2, though the ac.ual prac.ic.l situation is quite the opposite. In this researc., we addressed this problem by first applying a dense layer of Zn O on FTO followed by a mesoporous layer of interc.nnec.ed Zn O nanopartic.e layer, both were prepared by spray pyrolysis tec.nique. The best c.ll shows a power c.nversion effic.enc. of 5.2% when the mesoporous layer thic.ness is 14 μm and the c.nc.ntration of the N719 dye in dye c.ating solution is 0.3 m M, while a c.ll without a dense layer shows 4.2% under identic.l c.nditions. The surfac. c.nc.ntration of dye adsorbed in the c.ll with a dense layer and that without a dense layer are5.00 × 10^（-7） and 3.34 × 10^（-7） mol/c.^2, respec.ively. The c.ll with the dense layer has an elec.ron lifetime of-54.81 ms whereas that without the dense layer is 11.08 ms. As suc., the presenc. of the dense layer improves DSc.c.arac.eristic. of Zn O-based DSc..

Horton Plains (HP), one of the two montane forests in Sri Lanka and habitat to many endemic.spec.es of plants and animals, has been severely affec.ed by forest diebac.. Past researc. has identified a direc. link between soil pollution with c.dmium (c.) and the phenomenon of forest diebac.. As a c.nsequenc., forest diebac. is inc.easing proportionately to the soil pollution. Henc., this study foc.ses on identifying a c.st-effec.ive remediation tec.nique to neutralize soil c., and thereby reduc.ng forest diebac.. Soil samples were c.llec.ed from HP, mainly Thotupolakanda site whic. shows more than 90% severity of forest die bac., and bulked together. The soil was high (13.4) in organic.matter and low (5.42) in pH, and three soil amendments were tested in this researc. as;bio c.ar prepared using 1) rubber nut shells, 2) ric. husk, and 3) dead wood from HP. Eac. sample was spiked with 20 ml of 5 ppm (parts per million) c. solution, and four treatments a) soil + rubber-nut shell bioc.ar (T1), b) soil + ric. husk bioc.ar (T2), c. soil + wood-from-HP bioc.ar (T3), and d) soil only (T4), with five (05) replic.tes, were setup. During the first eight weeks after the applic.tion of treatments, it was observed that T1 showed the best performanc., by showing a c.nsistent trend in reduc.ng the available soil c., with T2 following c.osely. The interesting observation was that the natural forest soil (T4) was also able to buffer the loading of c.. At the c.ose of the experiment, it was observed that the available soil c. goes almost to zero, in less than 24 months.
