A photovoltaic cell may include a hydrogenated amorphous silicon layer including a n-type doped region and a p-type doped region. The n-type doped region may be separated from the p-type doped region by an intrinsic region. The photovoltaic cell may include a front transparent electrode connected to the n-type doped region, and a rear electrode connected to the p-type doped region. The efficiency may be optimized for indoor lighting values by tuning the value of the H2/SiH4 ratio of the hydrogenated amorphous silicon layer.
