Abstract
A procedure for generating UV photocells in the spectral band Δλ = 350–520 nm with internal amplification is presented. It is revealed that such photocells are characterized by a spectral sensitivity of S λ ≈ 1.3 A/W at a spectral maximum (λmax = 461 nm) and by an integral sensitivity of S int ≈ (25–30) A/lm, which is higher by thousand times than similar parameters of common UV cells. It is shown that photocells based on Zn x Cd1 − x S solid solutions used as a part of a cascade photo converter make it possible to increase significantly the cascade photo converter efficiency with respect to the existing Si and CdTe photocells.
