Dear Colleagues,
Welcome to the 8th Annual CdTe Photovoltaics Workshop, sponsored by US-MAC and hosted by the Wright Center for Photovoltaics at The University of Toledo’s Brady Center. This year’s organizing committee includes: Jim Sites (CSU); Asia Jones, Dingyuan Lu, and Gang Xiong (FSLR); Matt Reese (NREL), and Ambalanath Shan, Beth Bower, Randy Ellingson, Mike Heben, and Vijay Karade (UT).
A light breakfast will be available both Thursday and Friday morning, with the understanding that most attendees will eat at their hotel prior to coming to the conference.
A hot lunch will be provided on Thursday and box lunches will be available on Friday. Both will have a vegan/vegetarian option.
Thursday Evening Dinner (at no charge, will be catered by Ameera with a variety of food options including vegetarian and vegan) for all of you attending in person, to celebrate the CdTe PV community as well as our past and future successes. Dinner will follow immediately after the close of the Thursday afternoon schedule and will be held at the Scott Park Banquet Room. Transportation will be via carpools (again, UToledo will have several additional drivers available for transport). The drive takes 5 minutes, and we strongly encourage a prompt departure from UT so we'll ideally have time for a beverage and/or networking.
Looking forward to a great workshop!
The US-MAC CdTe Workshop team

You are welcome to park on UT’s main campus during the CdTe PV Workshop, but you must register for a permit prior to arriving on campus to avoid a hefty fine (about $75 per day). To do so, please click on the parking icon below and fill out the form no later than Thursday morning (October 24th), and indicate which days your vehicle will be on campus.
Note that your license plate must be visible to the camera-equipped parking enforcement vehicles that frequently survey the lots. This means that, to avoid a ticket, if there’s no front plate on your vehicle then do not back into a spot that will leave your plate out of view. If your license plate is out of view, you’ll get ticketed.
