Item Growth of (Cu2O)1-x (Cu2O)x thin films for PV applications(Sri Lanka Association for the Advancement of Science, 2013) Kalubowila, K.D.R.N.; Wijesundera, R.P.; Siripala, W.Item Electrodeposited CuO/Cu2O heterojunction for PV applications(Institute of Physics, Sri Lanka, 2015) Kalubowila, K.D.R.N.; Wijesundera, R.P.; Siripala, W.Anodic electrodeposition was carried out to grow CuO thin films on Ti substrate at a deposition potential of 700 mV vs. SCE in an aqueous solution containing 0.4 M CuSO4 and 3.0 M lactic acid. CuO thin films were annealed at 375 o C for 15 min in air to improve the surface quality prior to the growth of Cu2O films, in order to fabricate the heterojunction. After growth of n-Cu2O, zero bias spectral response and dark and light I-V characteristics in PEC were employed to investigate n-Cu2O growth conditions on p-CuO thin films. CuO/Cu2O heterojunction solar cells were fabricated by electrodeposition of n-Cu2O thin film on Ti/CuO electrode at -200 mV vs. SCE for 60 min in an acetate bath. Ti/CuO/Cu2O/Au solar cell structure was characterized using zero bias spectral response and dark and light I-V characteristics and the cell produced VOC of 290 mV and ISC of 2.63 mA/cm2.Item Electrodeposited (Cu2O)1-x (CuO)x/Cu2O heterojunction solar cell(Technical Ses., Institute of Sri Lanka, 2014) Kalubowila, K.D.R.N.; Wijesundera, R.P.; Siripala, W.Item Construction of Cu2O Thin Film based Light Detector(Proc. 28th Technical Sess. of Institute of Physics, Sri Lanka, 2012) Kalubowila, K.D.R.N.; Jayathilaka, K.M.D.S.; Siripala, W.; Jayanetti, J.K.D.S.Item Methods for improving n-type photoconductivity of electrodeposited Cu2O thin films(Semiconductor Science and Technology, 2014) Kalubowila, K.D.R.N.; Gunawardena, L.K.A.D.D.S.; Wijesundera, R.P.; Siripala, W.Item Growth of(Cu2O)1-x(CuO)x thin films for PV applivations(Srilanka association for the advancement od science proceedings of 69th Anuual Session., 2013) Kalubowila, K.D.R.N.; Wijesundera, R.P.; Siripala, W.
