Considering the complexities of tandem solar cells, what are the key material challenges in integrating perovskites with silicon for optimal performance?
The company is active in the space of single-junction, double-junction perovskite PV, and perovskite-silicon tandems. The speaker mentions that they will not go into details but will look at the kinds of materials they use.
The company started out by providing electron acceptor materials for bulk heterojunction OPV devices. They have progressively extended their activities, working in the space of electron transport layers (ETLs) and transparent conducting premiums, which can be used as top electrodes for OPV devices.
* Involvement in single and tandem perovskite PV
* Provision of electron acceptor materials for OPV
* Development of ETLs and transparent conducting premiums

How does targeted carbon nanomaterial manufacturing impact the performance and longevity of next-generation PV devices?
How does targeted carbon nanomaterial manufacturing impact the performance and longevity of next-generation PV devices?
The company focuses on the large-scale manufacturing of targeted carbon nanomaterials. This includes C60, C70, and single-walled nanotubes. These materials are positioned as solutions for the printed electronics industry.
The initial focus was on developing and manufacturing fullerene derivatives as electron acceptor materials for organic photovoltaics (OPV). The company is now active in the clean energy space, working on conducting additives for applications like batteries, and more recently, single-junction and tandem perovskite PV and perovskite-silicon tandem devices.

Given the unique electronic properties of C84, what specific device architectures or applications could best leverage its lower LUMO level compared to C60 and C70?
Given the unique electronic properties of C84, what specific device architectures or applications could best leverage its lower LUMO level compared to C60 and C70?
The absorption spectra of PC60, C70, and C84 are shown, highlighting the shift of the absorption spectrum to longer wavelengths. The LUMO level of C84 is approximately 0.3 electron volts below that of C60 and C70.
This lower LUMO level could lead to potential applications and an extended spectrum. The company supplies materials depending on the application, and whether or not they need to be degassed. Degassing can facilitate processing and has no impact on recycling.
