What is n type bifacial PV module advantage?

N type bifacial PV module advantage. A bifacial module is averagely 4.03% higher than that of a regular module for micro inverter. Bifacial modules is averagely 3.21% higher than that of the regular modules for string inverter. 1. Introduction N-type monocrystalline silicon solar cell is a high efficiency and low cost photovoltaic technology.

What are n-type bifacial c-Si solar cells?

The structure of N-type bifacial c-Si solar cells The solar cells in this work use a phosphorus-doped N-type wafer (1–2 Ω cm) as substrate. Compared to the standard P-type (boron-doped) silicon solar cells, N-type silicon solar cells feature two key advantages.

Do bifacial PV modules produce more electricity?

Outdoor testing results (year 2014). After one year outdoor testing in year 2014, it shows that the average daily electricity output of bifacial PV modules is averagely 3.21% higher than that of the regular ones. The energy output increasing is much higher in cloudy days and in low light intensity.

Why are n-type bifacial modules so popular?

Interest in N-type bifacial modules has rapidly increased due to their ability to generate more power than conventional P-type bifacial thanks to their higher bifacial factor, lower degradation, lower temperature coefficient in addition more energy density and power class.

Do bifacial solar cells produce more electricity?

For bifacial solar cells, the IR lights are susceptible to the reflection from the ground, and are accepted from the rear side of the solar cells and the electricity output is therefore enhanced (Robles-Ocampo et al., 2007 ). Several research institutes indicated that an improvement up to 30% can be expected ( Kreinin et al., 2010 ).

How are bifacial solar cells encapsulated?

Bifacial solar cells can be encapsulated in modules with either a glass/glass or a glass/ transparent backsheet structure.
