Senior R&D Technician, Space PV Prototyping

Tandem PV is a U.S.-based solar technology company specializing in the development and manufacture of perovskite-silicon tandem solar panels. The company combines thin-film perovskite layers with conventional silicon modules to produce panels that have achieved 30% efficiency, representing approximately 40% more power output in the same physical footprint compared to standard silicon panels. Tandem PV targets utility-scale solar infrastructure and is designed to integrate seamlessly into existing solar supply chains. The company's mission centers on restoring U.S. leadership in solar manufacturing and delivering a generational step change in solar performance at a time when global energy demand is surging due to AI growth, electrification, and energy security needs. Conventional silicon solar technology has approached its practical efficiency limits, and Tandem PV positions its perovskite-silicon tandem approach as the critical next phase of solar evolution, manufactured domestically in the United States. What distinguishes Tandem PV is its combination of industry-leading efficiency, demonstrated long-term durability — with accelerated testing showing less than 1% annual degradation — and a lower total cost of ownership by generating more energy per panel without significantly increasing cost per watt. The company holds a growing portfolio of patents covering perovskite-layer technology, system design, and durability innovations, and has attracted backing from notable investors including Eclipse. Former U.S. Energy Secretary Jennifer Granholm has joined its board, underscoring the company's strategic significance in clean energy.

At Tandem PV, we are a team of people who are passionate about building a more sustainable world by bringing cost effective solar panels onto the market. We’re scaling metal-halide perovskite solar technology to make best-in-class mechanically stacked tandem modules.   We have built efficient, durable cells, monolithic multi-cell submodules, and packaged modules with our scalable, low-cost process. Our next focus is expanding our team to work in our new pilot manufacturing facility.

Job Summary:

As a Senior R&D Technician, Space PV Prototyping, you will work with our engineers and technicians to build prototype solar devices for spacecraft on ultrathin and flexible substrates: preparing substrates, running deposition, coating and patterning tools, laminating covers, and measuring results. Much of what you handle is a fraction of a millimeter thick and hard to replace, so careful execution, exact adherence to written procedures and meticulous records are central to the role. Your work produces the consistent, well-documented sample sets that our development and test campaigns depend on.

To be great at this role, you will have:

• Clean, inspect, photograph and log substrates, and keep accurate inventory of limited, high-value materials.

• Load and run sputter and evaporation processes, including bake-outs and controlled pump-down and vent sequences.

• Coat and thermally process device layers to fixed recipes, and flag anything that looks different from previous runs.

• Set up and run laser patterning steps, then inspect the result under a microscope and measure electrical isolation.

• Laminate cover materials, including very thin ones, and inspect for voids and edge-seal quality; handle ultrathin substrates and release them from carriers once formally qualified.

• Perform routine metrology: sheet-resistance mapping, transmittance, profilometry, optical microscopy, luminescence imaging and current-voltage measurement.

• Keep run logs and per-part travelers (tools, recipes, temperatures, vacuum cycles, operator, timestamps), and prepare and ship sample batches to external test partners.

• Build, label, mount and wire coupon sets for test campaigns and exposure chambers, and perform routine tool care, including early warning when a tool starts to drift.

Qualifications:

• Steady hands and patience for delicate manual work; this is the single most important qualification for the role.

• Meticulous documentation habits: detailed, legible and consistent notes of processing conditions.

• Follows written procedures exactly, and speaks up when a procedure does not match what is actually in front of you.

• Problem-solving orientation and the ability to work autonomously once trained, as part of a team in a scientific or technical environment.

• Adaptability across a wide range of laboratory tasks and willingness to learn new concepts, tools and measurements.

• Comfortable with basic laboratory arithmetic, unit conversion, and reading a specification or drawing.

• Ability to perform the essential functions of the position, with or without reasonable accommodation, including working in a cleanroom environment while wearing required PPE and gowning; working on your feet for extended periods as required by laboratory activities; occasionally lifting, carrying, or moving materials weighing up to approximately 25 pounds; and safely working in laboratory and manufacturing environments where solvents, chemicals, and Class 4 laser systems may be present. Employees will be required to follow applicable safety procedures and complete required safety training.

Preferred Experience:

• Laboratory, cleanroom, semiconductor, display or precision manufacturing background, including handling thin glass, silicon wafers or display panels.

• Operation of vacuum systems, thermal evaporation or sputter deposition, solution coating (blade or slot-die), or laser tools.

• Experience in an ISO 9001, AS9100 or similarly controlled environment, or with fine assembly, soldering, precision dispensing or hermetic sealing.

This position may require access to technology and/or technical data subject to U.S. export-control laws. Any eligibility or access requirements will be applied in accordance with applicable U.S. export-control laws, regulations, licenses or authorizations, government-contract requirements, and applicable anti-discrimination laws.

Tandem PV uses perovskite & silicon mechanically-stacked tandems to upgrade silicon solar panels, sharply decreasing installed systems costs, significantly increasing module manufacturing profit margins, and opening up vast new solar markets in the US and worldwide. TPV was co-founded by Stanford PhDs Colin Bailie and Chris Eberspacher; is advised by industry experts from Corning, First Solar, Vivint Solar, and Kateeva; has raised more than $50M in Series A funding. We were recently recognized as the Best Pre-Commercial Venture of 2025 by the Industry Growth Forum (IGF)

We are a team of people who are passionate about building a more sustainable world by delivering a new generation of solar panels to the market. We are constantly growing and are always looking for dedicated, hardworking, and empathetic teammates.
