Evaluation of Bifacial Solar Energy Performance of a Cell with a Dual-Axes Tracker

A double-sided solar cell (a bifacial photovoltaic (PV) cell arrangement) consisting of two
back-to-back silicon photovoltaic cells is examined in this paper, and compared with a
Monofacial cell. It was installed on a two-axis solar tracker. Temperature and radiation
were monitored on sunny noonday in El-Marg city, Libya. The purpose of this
investigation is to demonstrate the generation and matching of bifacial solar cells made by
back-stacking two monoclinic solar cells. The face in the front accepts direct solar
radiation, while the face in the back accepts indirect solar radiation that is reproduced from
the ground, clouds, and surrounding buildings. The chief focus is on determining how
ambient temperature affects the performance of bifacial photovoltaic panels. On two hot
summer days in Al-Marg city, important photovoltaic parameters of the binary system
(short-circuit photocurrent density, open circuit photovoltaic voltage, maximum power
conversion efficiency) was verified. The PV performance of each individual cell shows
remarkable variability with the movement of the tracer to the effect of radiation and the
surface temperature of each cell. The results showed that the back cell performs better than
the front cell. Although the back cell was exposed to fewer illuminations, it provided the
front with higher power conversion efficiency than the front cell.
