What is bifacial photovoltaics?

Bifacial Photovoltaics: Technology, applications and economics provides an overview of the history, status and future of bifacial PV technology with a focus on crystalline silicon technology, covering the areas of cells, modules, and systems. In addition, topics like energy yield simulations and bankability are addressed.

What motivates bifacial photovoltaics?

A major motivation for bifacial photovoltaics (PV) is an expected additional energy yield, compared to monofacial panels, due to the two-sided light sensitivity.

Is bifacial PV the best technology for electricity generation?

All in all, bifacial PV—being the most cost-effective PV solution—is now becoming also bankable, it is becoming the overall best technology for electricity generation. However, when more detailed and precise simulations are required, it is necessary to use more advanced programs such as those developed at several institutes.

Do bifacial PV modules correlate with output power?

The figures reveal that GHI and DNI exhibit a stronger correlation with output power, regardless of the PV module type or configuration. Conversely, a contrasting trend is observed for DHI. Notably, bifacial PV modules demonstrate a slightly stronger correlation across all configurations.

Are bifacial PV modules irradiated?

Thereby, an optical model for the rear side irradiance of bifacial PV modules, both stand-alone as well as in-field installed, has been established and after its implementation as a software tool, simulations of the energy yield for different scenarios have been conducted.

Why was bifacial PV not bankable?

At that time, bifacial PV was not bankable, meaning the overall risks of the bifacial PV projects were not low enough for financing costs to be affordable. Private investors had to take the risk to prove the technology on a large systems level.
