Photovoltaic modules of “KVANT” with improved optical and electrical characteristics

This paper presents the results of the development of photovoltaic modules with bifacial sensitivity as well as modules with improved optical and electrical characteristics. Such modules have bifacial sensitivity due to the special design of Si solar cells. The paper presents experimental results on estimating the net gain in the rated module´s output power under various operating conditions. It was shown as a result that an additional output power was obtained (compared to conditions when only the front face is illuminated). Replacement of the frontal glass by the fluoroisopolymeric film has allowed minimisation of optical bases of the module
