State Scientific and Production Association "Optics, Optoelectronics and Laser Technology" offers consumers a Experimental samples of hybrid solar cells with increased efficiency and radiation resistance for solar batteries of spacecraft under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

A hybrid solar cell (SC) was designed and manufactured. It comprises a heat-dissipating crystalline silicon base measuring 104 mm x 54 mm x 0.25 mm with three integrated silicon SCs, current-carrying contact buses, and InGaP/Ga(In)As/Ge SCs assembled into power-generating arrays. The manufactured hybrid cell, with an optical system based on a pulsed simulator with a solar radiation spectrum of 0.136 W/cm², provided a specific electrical power of over 350 W/m². The use of an optical concentrating system reduces the overall dimensions of the InGaP/Ga(In)As/Ge SC and, consequently, reduces the cost of solar batteries with concentrators proportional to the solar radiation concentration ratio, while increasing radiation resistance due to the SC protection by optical design elements and significantly increasing the service life. The optical system's misorientation from the light beam along and across the linear focus of the lens concentrator, while maintaining output electrical power at up to 85% of its maximum, is ±22 degrees.

By using hybrid solar cells, the weight and dimensions of the photogenerating part have been reduced to 1.1 kg/m².

The main research activities of the SSPA "Optics, Optoelectronics and Laser Technology".

Fundamental and applied research in the field of radio photonics (microwave optoelectronics), the main subjects of study of which are the generation, transmission and processing of microwave signals using optoelectronic methods. Radio photonics allows you to create devices and systems in the microwave range with parameters that are unattainable by traditional electronic means, including:
– powerful photodiodes for frequencies up to 100 GHz;
– photon generation of microwave signals with a bandwidth of up to 100 GHz;
– fiber optic transmission lines and distribution systems for frequencies up to 100 GHz.

Research is underway on new solid-state and thin-film photovoltaic cells, methods for detecting and converting optical radiation by photoelectric detectors and radiation converters for monitoring, control, navigation, diagnostics systems, as well as photovoltaic cells for solar energy and methods for their metrology.

Research is being carried out on:
— formation and study of new functional materials based on modified anodic alumina;
— development of functional elements and systems for micronanoelectronics, optoelectronics and micromechanics;
— development of design options for physical and chemical sensors operating on various physical principles;
— development of micro- and micro-optoelectromechanical systems (MEMS and MOEMS);
— development and research of various functional micro- and nanodevices for biotechnologies and filtration and separation systems.

Applied research is also being carried out in the field of distributed robotic and computing systems, intelligent automation systems, automated laser-optical and optoelectronic systems. Creation of modular distributed hardware and software systems with a flexible network system for remote interaction, separation of hardware resources and computing power. Such systems with wired and wireless communication between components have high fault tolerance, easy interchangeability of modular components, lack of dependence on network infrastructure and are focused on a wide range of applications: smart home systems, industrial automation systems, etc.

SSPA develops scientific and technical cooperation with organizations and enterprises of the Republic of Belarus working in the field of micro-, opto- and microwave electronics. To this end, in February 2017, the Micro-, Opto- and Microwave Electronics cluster was created. The cluster includes:
