The paper examines the effect of temperature on the surface recombination rates of solar cells and sensors created on the basis of p-CdTe – n-CdS and p-CdTe – n-CdSe film heterostructures. It has been established that the surface recombination rates S at the heterointerface at N to infinity, but tend not to infinity, but to a finite drift velocity in the boundary electric field. It is shown that the carriers are separated not at the interface of CdS and CdTe, but in the depth of the CdTe layer, which is equal to several micrometers from the surface, which is associated with the formation of a layer as a result of the diffusion of a free cadmium atom in p-CdTe. The article also discusses the use of a photodetector based on p-CdTe – n-CdS and p-CdTe - n CdSe in optical sensors for determining polluted air. It was found that the created optical sensors with a programmed control framework for the utilize of microcontrollers in wide ranges of the IR range. By increasing the temperature of the optical sensor, uniformity of sensitivity and a significant reduction in the influence of background signals are achieved. It is shown that with the use of an optical sensor, it is possible to determine the dustiness and smoke of the air in rooms and open areas of the earth.
