How do bifacial solar cells perform under STC conditions?
Transmission through the cell, subsequent reflection on module cover layers and a second absorption of light in the solar cell leads to additional gains in the range of 0.5 – 0.8% for bifacial cells in modules with reflecting rear cover materials (i.e. white backsheets) under STC conditions.
How does reflection affect bifacial transmission in solar cells?
Transmission, subsequent reflection on module cover layers and a second absorption of light in the solar cell leads to additional gains in the range of 0.5 – 0.8% for bifacial cells in modules with reflecting rear cover materials (i.e. white backsheets). Transmission gains in modules with absorbing or transparent rear covers can be neglected.
What are bifacial solar cells?
In contrast to monofacial cells, bifacial solar cells are able to harvest sunlight from both front and rear side. Bifacial cells can be encapsulated into different module structures: glass/glass, glass/transparent backsheet or glass/backsheet.
Why do bifacial PV modules have a transparent rear side?
Bifacial PV modules with a transparent rear side collect additional sunlight on the rear side of the module as they capture light reflected from the surface beneath the module and from the surroundings (albedo). As a result, bifacial modules generate additional energy under outdoor conditions [9-11] compared to the standard monofacial modules.
Should bifacial cells be incorporated into photovoltaic modules?
By introducing bifacial cells into photovoltaic modules, existing models for cell-to-module (CTM) efficiency analysis or yield prediction are no longer sufficient due to additional optical effects within the photovoltaic module such as additional relevant internal reflections .
Are bifacial cells better than monofacial solar cells?
Cover coupling gains for bifacial cells are higher compared to monofacial cells (20%rel in modules with white backsheets). Today, photovoltaic modules mainly use monofacial solar cells that are only capable of converting irradiance from the front side into electrical power.
