Document Title
High-Efficiency Perovskite Tandem Modules with Resilient Interfaces
Document Type
NOE - Notice of Exemption
Project Applicant
The Regents of the University of California, San Diego

Document Description
The purpose of this Agreement is to develop robust, high-power perovskite-on-silicon tandem photovoltaic (PV) modules that achieve a power conversion efficiency of greater than 32% using low-cost manufacturing approaches. The perovskite top cell will be deposited on textured silicon cells, increasing energy production by 30% when the sun is near the horizon, reducing the ramp rate necessary for other grid participants, and improving reliability at future high PV penetration that is under statutory mandate. This Agreement will result in ratepayer benefits of greater reliability, lower costs, and improved safety by developing PoSiT technology that use mechanically compliant conductive adhesives to robustly integrate tandem cells into durable modules.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Cal. Code Regs., tit 14, § 15301 ; Cal. Code Regs., tit 14, § 15306
Reasons for Exemption
The proposed research project would involve developing a perovskite-on-silicon tandem photovoltaic (PV) panel that would be increase efficiency than current silicon PV panels. The durability of this module will be demonstrated via accelerated indoor stress tests and validated by real-life outdoor performance for at least six months on UC San Diego's energy technology testbed, which includes installation of small electronic components for testing. The project would include encapsulate the shingled tandem cells into a glass-glass mini-module format of at least 100 cm2 area. Additionally, the proposed project consists of research and data collection activities on the performance of the perovskite solar cells and tandem PV module, which do not result in a serious or major disturbance to an environmental resource. Based on the above project description, the project is classified as exempt from the provisions of CEQA under Section 15306, Information Collection and Section 15301, Existing Facilities. In addition, none of the exceptions to the exemptions apply. A Notice of Exemption (NOE) will be filed with the Office of Planning and Research at the time of project approval.
