SunShot Initiative Projects in Pennsylvania

The U.S. Department of Energy SunShot Initiative is a national effort to support solar energy adoption by making solar energy affordable for all Americans through research and development efforts in collaboration with public and private partners.

 SunShot funds cooperative research, development, demonstration, and deployment projects by private companies, universities, state and local governments, nonprofit organizations, and national laboratories to drive down the cost of solar electricity.

Pennsylvania is home to 21 current and past SunShot Initiative projects.

Research, Development, and Deployment

Finding Pennsylvania's Solar Future

  • Awardee: Pennsylvania Department of Environmental Protection
  • Location: Harrisburg, PA             
  • Award Start Date: 2016
  • Status: Active
  • Funding Opportunity Announcement (FOA) Name: Solar Energy Evolution and Diffusion Studies 2 - State Energy Strategies (SEEDS2-SES)
  • Total Government Share: $550,000

This project uses detailed scenario modeling to analyze current solar development and legislation and determine how they will be applied in 2030 under a scenario where up to 10 percent of electricity sales are from solar generation. The project will inform strategies that help meet state energy goals, develop environmental compliance plans, contribute to Pennsylvania's compliance of the Clean Power Plan, and increase grid resiliency. This work will result in a well-informed solar deployment plan that will be available to policymakers, regulators, industry, investors, and consumers. This project is expected to help lower the costs, increase the speed, and lower the barriers to solar market expansion in Pennsylvania.

Tunneling Back-Contacted Silicon Photovoltaics 

  • Awardee:  Lehigh University

  • Total Government Share: $117,291

This project is investigating the introduction of atomic layer deposited (ALD) tunnel barriers that simultaneously allow electron flow and passivate the silicon surface for silicon-based solar cells. The tunnel barrier is combined with metal oxide materials that selectively transport electrons or holes. This work employs ALD for the fabrication of these thin film layers, which is a scalable technique capable of sub-nanometer control of film thickness, even on non-planar substrates. This work quantifies the electronic behavior of these contacts, which may constitute some of the most efficient electrical contacts to silicon photovoltaics to date.

Solar in Your Community Challenge

The Solar in Your Community Challenge is a $5 million prize competition funded by the U.S. Department of Energy SunShot Initiative that aims to expand solar electricity access to low and moderate income (LMI) households; state, local, and tribal governments; and nonprofit organizations. 

The Challenge is supporting dozens of teams across the country with cash prizes and technical assistance to demonstrate innovative, scalable business and financial models that can open new solar markets that benefit these underserved communities.  

Teams are competing for up to $1 million in final prizes for the most innovative and scalable models. To compete, teams must design and deploy scalable community-based solar projects or programs, up to 5 megawatts in 18 months that serve at least 20% LMI households or 60% non-profits.
