Hybrid photovoltaic modules: comparison of lab and field research

Operating modes of a hybrid photovoltaic module based on A$_3$B$_5$ and Si-HJT heterostructure solar cells have been investigated. An increase in the concentrator module power generation due to the planar circuit under a changing balance between direct and total solar radiation was estimated. An increase in the planar circuit power generation in the single-facial and bifacial modes was determined: a more than double increase in the circuit photocurrent was fixed. Taking into account the temperature correction, a similarity between the laboratory measurements of photovoltaic characteristics of the solar module circuits and field research data has been shown for comparable irradiances.
