The research considered the Solvo-Thermal method of growing PbTe on non-conducting glass substrate. Cadmium Sulphide thin-film was deposited and used as the n-type absorber layer. On the internal parameters studied, the PbTe nano-film has thickness of as measured through gravimetric analysis; the optical absorbance studied through the use of UV-750 Series spectrophotometer showed a stable absorbance within the visible wavelength (390 nm – 700 nm) and optical band gap energy of was obtained as
