摘要： The present invention relates to the use of a material comprising at least one compound of formula (I): BiCu
1-z O
a S
b Se
c Te
d (I), where 0 ≤ z ≤ 0.2; 0 ≤ a ≤ 2; 0 ≤ b ≤ 2; 0 ≤ c ≤ 2; 0 ≤ d ≤ 2; and a + b + c + d = 2, as a p‑type semiconductor, for providing a photocurrent. The invention also relates to the photovoltaic devices using these semiconductors.
