Black23 Series NSEY Ultra-Efficient Bifacial

What are bifacial solar cells?

However, bifacial solar cells differ from monofacial solar cells in that they have several design prerequisites. The most crucial of these is integrating a transparent top contact and hole transport layer (HTL) layers into the cell to ensure that light entering from the back surface can effectively reach the active region.

Can bifacial solar cells outperform monofacial cells?

Bifacial solar cells can outperform monofacial cells by exploiting sunlight reflected off the ground surface. De Bastiani et al. show that bifacial perovskite/silicon tandem with an optimized bandgap can deliver a power density of 26 mW cm–2 and compare its performance to monofacial cells under outdoor conditions.

Are bifacial solar cells suitable for building-integrated photovoltaic applications?

This bifacial design enables promising applications for building-integrated photovoltaic applications. Semi-transparent perovskite solar cells (ST-PSCs) featuring high performance and light transmittance are highly desirable for building integrated photovoltaic (BIPV) applications.

What makes a bifacial SC different from a monofacial SC?

In contrast to monofacial SCs, bifacial SCs entail numerous design prerequisites. Foremost among these is the seamless incorporation of transparent top contact and HTL structures within the cell architecture, facilitating effective light ingress from the rear surface to the active region.

How efficient are bifacial St-PSCs?

Further bandgap engineering of the perovskite light adsorber (1.6 eV) leads to the design of highly efficient bifacial ST-PSCs, achieving a power conversion efficiency of 15.58 % when illuminated from the conductive glass side and 9.67 % from the top electrode side, both under 1 sun illumination.

Which bifacial device is best for building-integrated photovoltaic applications?

Bifacial devices are achieved with efficiencies of 15.58 % from the glass/ITO and 9.67 % from the Au/TiO 2 electrode side. The champion device (opaque Au electrode) shows an efficiency of 18.47 %, which is among the best in this field. This bifacial design enables promising applications for building-integrated photovoltaic applications.
