LASER LIGHT RECEIVER-TRANSDUCER Russian patent published in 2017 - IPC H01L31/52 

FIELD: electricity.

SUBSTANCE: proposed laser light receiver-transducer comprises a load-bearing structure with a receiving plane with S_RP area mounted on it, on the outer side of which the photoelectric transducers based on semiconductor photocells with an internal photoelectric effect are uniformly distributed for the direct transduction of the electromagnetic radiation energy of a circular laser beam with d_u diameter, whose axis is directed to the geometric center of the receiving plane, wherein the photocells are mutually connected serially-parallelly, are made with an antireflection coating and are equipped with a cooling system. The receiving plane consists of n modules, each of which is made with s area, and structurally represents a single unit consisting of m photocells with s_PC area each, identical in construction, composition and electrically isolated from each other. The photocells, one of each module, are integrated by parallel connection into i groups, each containing j photocells, and the groups are successively connected into a chain, where in each group there are q photocells from the chain, belonging to k modules completely falling into the light spot area of the circular laser beam incident on the receiving plane. The following conditions are taken into account: s<<S_RP; n>1; m>1; i=m; j=n; q=k, where 1≤k≤n, ensuring the maximum output electrical power of the receiver-transducer, determined according to the proposed equation.

EFFECT: increase in energy efficiency characterized under conditions of uneven intensity of laser irradiation with the minimum possible reduction in power at the output lines of the receiver-transducer with respect to the total power produced by all photocells, increase in efficiency of the receiver-transducer by reducing the spread of electrical parameters of groups from paralleled photocells and unification of the photovoltaic module design, which allows to standardize the technology of switching the photocells of the receiver-transducer.
