Bulk-heterojunction structured small-area organic solar cells are approaching 20% power conversion efficiency, but the blurred film-forming kinetics in the fabrication of large-area devices causes significant PCE loss and restrains the potential of commercialization.

6 Frequently Asked Questions about “Coated Photovoltaic Cells Video Tutorial Collection”
How do you make organic photovoltaic cells?
Organic photovoltaic cells ( OPVs) or organic light emitting diodes (OLEDs) can be easily manufactured using Ossila's pre-patterned ITO substrates and a few simple spin coating and evaporating steps. This article, and its companion video, will guide you through this process and offer hints and tips for how to get the best devices.
What do solar cells do?
This is a simple explanation of what solar cells do and how they may be used to provide energy in the future. This short animated video from TVNZ demystifies some of the technical language. What are solar cells? Solar cells convert light from the sun directly into electricity. Sunlight is made up of tiny packets of energy called photons.
How do solar cells convert light into electricity?
Solar cells convert light from the sun directly into electricity. Sunlight is made up of tiny packets of energy called photons. When sunlight hits a solar cell, the photons knock free minute particles called electrons contained inside. As the electrons begin to move about they are 'routed' into a current.
Can an OPV be evaporated or spin coated?
The charge transport and active layers for an OPV or OLED can be evaporated or spin coated depending on the material used. This video shows conventional architecture OPVs, which means the hole transport layer (HTL) is the first layer coated onto the ITO after cleaning. The next step is to spin coat the HTL.
Can a final charge transport layer be spin coated or evaporated?
The final charge transport layer can be spin coated or evaporated. For our OPVs an electron transport layer (ETL) of PFN-Br was spin coated on top of the active layer at 3000rpm for 30 seconds. A solid concentration of 0.5mg/mL in methanol was used.
How do you encapsulate OPV & OLED?
In most cases the final OPV or OLED should be encapsulated to prevent rapid degradation on exposure to air. Ossila's encapsulation epoxy should be placed in between the active area and a glass slide and cured to a solid using UV light. A glass pipette without a pipette bulb can be used to deposit a drop of epoxy onto the substrate.
