Why Bifacial Module’s Share Gets Larger and Larger in the Solar market

The bifacial module is a type of solar module that can capture and harvest sunlight from both sides of a module side. According to the Wood Mackenzie Consultancy, bifacial modules will make up 17.2% of all modules in service till 2024. A conservative estimation suggests the technology’s capacity will exceed 21GW. It is important to note that bifacial modules have achieved rapid development in recent years. Its global installed capacity has risen up from 97MW in 2016 to 7GW in 2019. Therefore, it will be increasing its share more than two times over the next five years.

Now, the question is why they become more popular than mono-facial over recent years?

The main and obvious reason is that bifacial modules are produced more power compared to mono-facial modules because of harnessing sunlight from both sides. It is also noting that mono-facial module manufacturers can easily produce bifacial modules with negligible changes in the balance of their systems. Except for standard Back Surface Field (BSF) modules, it is enough to add rear cell interconnections to conventional technologies in the cell level of industrial manufacturing. 

BSF is an old technology that was being used in solar module manufacturing. BSF consists of a higher doped region at the rear surface of the solar cell.
