研究目的
To investigate the study of the response of the photocell and the parameters of recombination in a magnetic field B. It is also related to the study of the static characteristic I-V and electrical parameters Rs and Rsh under a magnetic field.
研究成果
The study concludes that the presence of grain size in the medium reduces the capacitance of the solar cell, and larger grains with lower recombination velocity provide higher solar cell capacity. The solar cell capacitance is of good quality, and the conversion efficiency is very dependent on the applied magnetic field.
研究不足
The study focuses on a specific model of a bifacial solar cell under certain approximations, and the effects of the magnetic field and grain size are considered within a limited range of values.
