What is a bifacial solar cell?

Instead, a bifacial solar cell is designed in such a way that the cell will produce a photocurrent when either side, front or rear, is illuminated. BSCs and modules (arrays of BSCs) were invented and first produced for space and earth applications in the late 1970s, and became mainstream solar cell technology by the 2010s.

What is the difference between monofacial and bifacial solar cells?

In contrast, monofacial solar cells produce electrical energy only when photons impinge on their front side. Bifacial solar cells can make use of albedo radiation, which is useful for applications where a lot of light is reflected on surfaces such as roofs.

How are bifacial solar cells deposited?

The front-sided and back-sided solar cells are symmetrically deposited on a Mo foil using simultaneous one-time process. The bifacial solar cell with the same structure and morphology obtain the PCEs of 9.3% and 9% for two sides, respectively.

Are bifacial solar cells suitable for indoor lighting?

Indoor lighting is weak and multi-directional, thus the requirement for photovoltaic differs from that designed for outdoor. To efficiently harvest the indoor energy, the authors designed CZTSSe bifacial solar cells on flexible Mo substrate using double-sided deposition to ensure consistency and to save cost.

How efficient are bifacial solar cells?

The bifacial solar cell with the same structure and morphology obtain the PCEs of 9.3% and 9% for two sides, respectively. Under weak LED light illuminations with 1.5–18.5 mW/cm 2 intensities, the devices also show good performance of 6–8.8% efficiency.

Where are bifacial solar panels located?

Vertical solar panels, east to west orientation, with bifacial modules near Donaueschingen, Germany. A bifacial solar cell (BSC) is any photovoltaic solar cell that can produce electrical energy when illuminated on either of its surfaces, front or rear.
