Bismuth telluride thin films have been grown by close space vapor transport (CSVT) technique as a function of substrate temperature ( T sub ). Both N- and P-type samples can be obtained by this method which is a relatively simple procedure, which mak

CdTe films with different compositions (Cd-rich, Te-rich and stoichiometric) were fabricated by a novel and low cost chemical molecular beam deposition method (CMBD) in atmospheric pressure hydrogen flow. Cd and Te granules were used as precursors. T

In previous papers we have reported the improvement of the efficiency of CdS/CdTe solar cells by varying the thiourea/CdCl 2 ratio ( R tc ) in the chemical bath solution used for the deposition of the CdS layers. In this work, a more complete study c

Polycrystalline thin film CdS/CdTe heterojunction solar cells are important candidates for large scale photovoltaic applications. In this work we use a C–V (capacitance vs. voltage) theoretical method for the determination of the interface charge d

The controlled increase of hole concentration is an important issue and still an unsolved problem for polycrystalline CdTe-based solar cells. The typical hole concentration of as-grown CdTe thin-films goes up to 10 13 cm − 3 , depending on the spec
