EK Technology Photovoltaic Bifacial Modules

What is bifacial solar photovoltaics (PV)?

Bifacial solar photovoltaics (PV) is a promising mature technology that increases the production of electricity per square meter of PV module through the use of light absorption from the albedo.

Can bifacial photovoltaic modules improve the performance of building application?

Potential approaches to improve the performance of building application are proposed. Bifacial photovoltaic (bPV) modules can both obtain the front and rear light to get higher power output, which has attracted extensive attention and is expected to substitute for mono-facial photovoltaic technology (mPV).

How bifacial PV technology affects the power generation effect?

At the same time, there are some potential problems in the bifacial module, such as the conventional bracket form will block the back of the bifacial PV module, which not only reduces the backlight but also causes the series mismatch between the cells in the module, affecting the power generation effect. Fig. 1. (A) Schematic of bPV technology.

Do bifacial PV modules have different backsheet materials?

Bifacial PV modules in the PV market have two different backsheet materials, namely glass and transparent organic material, whose characterizations are listed in Table 1. Different materials with different characterizations provide the PV market with selective chance under various conditions. Table 1. Characterizations of bPV backsheet materials.

Does bifacial PV module output decrease?

Initial works in this area shows a decrease in bifacial PV module output (bifaciality factor: 73%) when comparing a single PV module (108×26 cm 2) and a stack of 5 PV modules separated from each other 20 cm and placed above a white wall (85% reflectivity) .

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.
