These are exciting times in the world of PV but challenging times to secure federal government research funds.
The University of Delaware’s Institute of Energy Conversion hosted the 3rd SunShot Thin Film Photovoltaic Workshop on October 20 and 21, 2014. The workshop featured presentations by researchers from industry, national laboratories and universities and was complimented by discussions after the topical session on CuInGaSe2, CdTe, Cu2ZnSn(S,Se)4 and Measurement & Analysis. The event delivered on its promise to be highly informative with the goal of identifying future needs to advance these technologies.
On the research front, there have been many exciting developments:
- Bill Shafarman and his team have been making steady progress on a new front-wall CuInGaSe2 device structure.
- Brian McCandless who leads our program on Cu2ZnSn(S,Se)4 has made significant progress on growing and characterizing single crystals of Cu2ZnSn(S,Se)4 and is now making solar cells on the crystals.
- Steve Hegedus and his team have fabricated an all back contact c-Si heterojunction device with efficiency over 18% using a low temperature process and is making significant progress on laser fired contacts to an n-type wafer.
Finally, I want to wish Erten Eser an enjoyable retirement - we will miss your expertise at IEC.
