In the Solar Power Lab at Arizona State University, we work with academic, industrial, and governmental researchers across the U.S. and around the globe. The lab and its research activities are mostly supported by QESST- an NSF/DoE  funded Engineering Research Center ( NSF ERC). We also receive partial support through the NSF Nanotechnology Collaborative Infrastructure (NCI-SW). 


The lab is located at MacroTechnology Works in ASU research Park. In a state-of-the-art clean room with sophisticated semiconductor processing and metrology equipment, we  have an industrially-compatible complete fabrication line for diffused junction and heterojunction silicon solar cells. The facility includes 6,000 sq ft of cleanroom space equipped with a full suite of tools supporting silicon solar cell fabrication from wafers to modules. In addition, SPL has  a twelve source molecular beam epitaxy (MBE) tool for layer by layer growth of III-V materials for nanostructured and multijunction solar cells. All of these tools and associated services are available to external users from industry and university.

The Solar Power Lab works with industrial and university partners in multiple ways:


1. QESST membership (QESST website or contact John Mitchell); ​multiple levels of membership are available ranging from informal to strategic partnerships.

2. Service work where pricing is determined by processing requirements

  • ​A "recharge center" tool is used to calculate charges for billable activiit
  • Material cost is calculated based on the run in lots of up to 12 wafer
  • Single-step processing (e.g., POCl3 diffusion), full-flow solar cell fabrication, or anything in between from cells to module fabrication steps orders are taken
  • Technologies supported includes several silicon architectures as well as III-V cells
  • Module fabrication capabilites exist up to 1 m x 1.5 m in size
  • A complete list of available equipment is here

3. Sponsored research (either directly or in collaboration with the funding provided by an other source such as SBIR, DOD, DOE)

4. Solar Cells 101 (Training on solar cell fabrication REU/RET, QESST industry members)

It is common to use a combination of these pathways for work with the Solar Power Lab.
