Request for Information: Physics of Reliability Photovoltaics Technology

Open Date: 04/10/2012

Close Date: 04/24/2012

Funding Organization: SunShot Initiative

Funding Number: DE-SOL-0003956


The DOE SunShot Initiative seeks feedback from industry, national laboratories, and members of academia relating to the physics of reliability in photovoltaic (PV) devices. The wide diversity of deployment conditions for PV systems leads to a variety of failure mechanisms that require physics-based modeling for improved understanding and prevention.

PV modules are exposed to severe operating conditions involving temperature, thermal cycling, UV radiation, humidity, environmental weathering, electrical, and other stresses. Limited understanding exists on the fundamental degradation mechanisms and the service life for materials, such as encapsulants, solders, interconnections, and semiconductor layers, under single or combined stress conditions.

This request for information seeks to identify PV failure mechanisms that could improve the testing, design, and bankability of solar energy products.

For more information, see the full solicitation.
