OUR STORY
Tandem PV was founded in 2016 to build a new kind of solar panel, one that captures more energy from the sun and can be made at commercial scale in the United States.
Using perovskite-silicon tandem technology, the company’s high-efficiency solar panels integrate into existing manufacturing supply chains, and can be rapidly deployed to support booming electricity demand from AI, electrification, and data infrastructure.
The company’s roots trace back to pioneering perovskite-silicon tandem research by founder and CTO Colin Bailie at Stanford University, where he developed the first such tandem solar cell. Bailie partnered with long-time solar industry veteran Chris Eberspacher to form the company, combining breakthrough materials science with decades of experience translating new technologies into commercial solar products.
As the technology matured, Tandem PV built a leadership team to support the next phase of the company’s growth. Under the leadership of CEO Scott Wharton, the company has focused on designing its technology to be manufactured at scale, assembling deep expertise in high-volume solar manufacturing and operations, and aligning the organization for commercialization and production.
Today, Tandem PV is advancing U.S.-based manufacturing of high-efficiency tandem modules, combining high efficiency, demonstrated durability, and long-term bankability.
As solar becomes the backbone of new power generation worldwide, perovskite-silicon technology represents the most significant solar advance in decades — reshaping the economics of global electrification. Tandem PV is at the forefront of that shift.
“From the beginning, it was clear that low-cost tandem solar was the next frontier. The challenge — and the opportunity — was not just achieving higher efficiency, but turning that potential into a product that could be manufactured reliably and deployed at scale.”
- Colin Bailie, Founder & CTO
“What makes Tandem compelling today is the combination of differentiated technology and an execution-driven team. The company is entering the phase where manufacturing discipline, durability, and scale matter most.”
- Scott Wharton, Chief Executive Officer
“With the core technology in place, Tandem PV is focused on market readiness — building the partnerships, manufacturing pathways, and customer confidence required to deploy a next-generation solar product at scale.”
- Saritha Peruri, Vice President of Commercialization
Our Leadership Team
We are a close-knit team united by a mission to build a cleaner, more secure energy future. Our shared commitment to advancing American energy independence drives us to push the boundaries of science and technology every day. With deep expertise in research, manufacturing, and large-scale deployment, we are developing breakthrough innovations backed by a growing portfolio of patents. Supported by $100 million in funding from leading investors—led by Eclipse Ventures—and strengthened through partnerships with U.S. government agencies and research institutions, including the Department of Energy, National Science Foundation, California Energy Commission, and Lawrence Berkeley National Laboratory, we are building the foundation for America’s next era of solar leadership.
