Novel solid state solar cell made from n-cu2o using Bamboo Powder active carbon as upper - electrode

Abstract

Bamboo is a natural vegetable fibre. They are widely distributed throughout parts of the world, particularly in the Asia-Pacific region. Activated carbon was prepared by one step pyrolysis by treating with 0.1M KOH of scoured bamboo ball billed micro particles at 3500C heat rate of 10 cm-1 in the nitrogen atmosphere for 0.15h. Iodine number was determined to acid washed all carbon sample. Powder activated carbon was characterized with SEM. The copper plate was fabricated by using a thin film of Cu2O which is formed by boiling (5*10-3M) solution of copper sulphate for 60 min. After a solid state photovoltaic cell Cu/n-Cu2O/BPAC/ITO were made have BPAC acts as the upper electrode of the solid state solar cells.it was formed that n-Cu2O / BPAC contact forme schottky barrier junction to separate photo generated charge carriers, forming a solid state photovoltaic device. UV Absorption spectra, FTIR spectra. V- I characteristics and photocurrent development with time were used to compare photovoltaic characteristics of solid state thin film solar cell from this study.
