Abstract—A synthetic diamond based heterostructure (p-i-structure) is examined as a photovoltaic cell. P-type diamond heavily doped with boron was used as a substrate. A CVD IIa-type diamond film of 50 mkm thickness was deposited on the substrate.
A technology of semi-transparent entrance contact fabrication was developed. A current-voltage characteristic (I-V) of the wide band gap diamond photovoltaic cell were measured. For the case of UV irradiation the comparison of I-V for ordinary and semi-transparent contacts was performed. Experimental data allowed estimating of alpha, x-ray and UV radiation conversion efficiency to be in the range5÷7%.
Index Terms—Boron doped diamond, CVD diamond, diamond heterostructures, photovoltaic cell, semi-transparent contact.
