How can a perovskite solar farm transition from the laboratory?

This transition from the laboratory can be achieved by extending the impressive results obtained in terms of PCE and stability 3 on small-area cells to large-area modules and panels, and, more importantly, by assessing the energy-generation capability of a perovskite solar farm installation under outdoor conditions.

Can a perovskite photovoltaic technology be used in a solar farm?

A.DC., F.B. and E.K. “Deployment of perovskite photovoltaic technology requires demonstration of scalability, manufacturability and field operation of the devices. The solar farm demonstration presented here ticked all these boxes, moving the field away from laboratory prototypes and towards real-world application.

How to bridge the gap between laboratory prototypes and solar farms?

To bridge the gap between laboratory prototypes and solar farms that operate outdoors, we exploited the know-how developed in the use of 2D materials for the interfacial engineering and scaling-up of PSCs 4 to realize 2D materials-based perovskite solar panels (termed, GRAphene–PErovskite (GRAPE) panels) 5.

How scalable is a solar farm?

The solar farm delivered a peak power exceeding 250 W, proving the scalability of the proposed technology. The energy production of the solar farm was monitored over 8 months, demonstrating a remarkable stability: we detected only a 20% reduction in the PV performance over 5,832 hours of operation.

Are solar cells stable in outdoor operation?

Despite significant improvement of PSC stability towards light, heat, and humidity achieved over recent years,2,3 this class of solar cells' stability in outdoor operation remains almost unexplored.

How to encapsulate solar cells?

Solar Cell Encapsulation To access the contacts of the cells after encapsulation, tinned copper solar ribbons (Ulbrich, part#7746-9062) were glued with a polyurethane conductive adhesive (Polytec PU1000) to the cathodes and anodes on the 25 × 25 × 1.1 mm 3 substrates. The glue was cured at 100 °C for 10 min.
