6 FAQs about [Silicon photovoltaic cell in open circuit state]
Does recombination reduce open-circuit voltage in solar cells?
Recombination at the metal-silicon interface is a major cause of the drop in the open-circuit voltage (V oc) of a solar cell. Thus far, the study of electrodes in silicon solar cells has been largely aimed at reducing the series resistance, and few studies on recombination due to electrodes have been performed.
How efficient is a silicon heterojunction solar cell?

Why are BC solar cells better than Si based solar cells?
Eliminating shading losses enables all incident light to penetrate the solar cell structure. As a result, BC solar cells produce higher photocurrent and exhibit greater PCE compared to traditional sandwiched Si-based solar cell structures.
How efficient is a c-Si solar cell?
