Research on the Influence of Environmental Conditions on Electrical Parameters of Interdigitated Back Contact Monocrystalline Silicon Solar Cells

摘要

This article presents results of the experiment carried out on the samples of HIT-IBC solar cells. Devices under test have been placed in the climatic chamber in constant ambient temperature from a range (-20 ÷ 100)℃ and exposed to irradiation of energy ranging from 700W/m~2 to 1250W/m~2 and spectral composition corresponding to solar spectrum. Measurements of I-V and P-V characteristics have been performed. Results of the analysis have been discussed in the context of photoconversion efficiency in variable irradiation conditions.
