TwoPhold

TwoPhold is a New Zealand clean-energy startup working on advanced materials designed to improve the efficiency of solar panels. According to its official website, the company is developing "next generation photovoltaics" technology that aims to harness more energy from every ray of sunlight. Its core innovation addresses a fundamental loss mechanism in conventional solar cells: when high-energy light strikes a standard cell, the excess energy is lost as heat. TwoPhold's technology captures this otherwise wasted energy by splitting a single photon into two usable charges, thereby generating more electricity from the same amount of sunlight. The company states that this approach can push solar cells beyond the conventional efficiency limit of approximately 32%, approaching roughly 44%. A key differentiator of TwoPhold's solution is that it is solution-processable. The technology is built directly into perovskite "inks," which enables low-cost, scalable manufacturing methods including roll-to-roll printing. This means the efficiency gains can potentially be integrated into existing perovskite solar cell production without adding significant cost. TwoPhold is actively partnering with perovskite developers to integrate and optimize its technology in real devices, positioning itself as a technology provider rather than a panel manufacturer. The company is led by a small founding and technical team. Nathaniel Davis serves as CEO, Co-Founder, and Co-inventor, overseeing project management, science direction, and commercial direction. Nikita Shumilov is CTO and Co-founder, responsible for research and development and commercial direction. Chase Zemke-Smith works in research and development, while Adit Batra is a PhD student and Jodi Carter and Dillon Anderson are listed as interns. The team's combined focus spans both the scientific development of the photon-splitting materials and the commercial partnerships needed to bring the technology to market. As a startup, TwoPhold operates in the emerging field of advanced photovoltaics, where competition is driven by the need to improve solar cell efficiency while reducing manufacturing costs. Its value proposition centers on delivering higher efficiency at no added cost by integrating with existing perovskite manufacturing processes. The company is based in New Zealand and is currently in a development and partnership phase, working to validate and scale its technology with industry collaborators.

TwoPhold is a New Zealand clean-energy startup focused on next-generation photovoltaics. The company emerged from research into advanced solar materials, specifically the challenge of excess energy loss in conventional solar cells. In standard photovoltaic cells, when high-energy photons are absorbed, the surplus energy beyond the bandgap is rapidly lost as heat, a phenomenon that limits practical efficiency to around 32%. TwoPhold's founding team, led by CEO Nathaniel Davis and CTO Nikita Shumilov, developed a technology that addresses this loss by splitting a single high-energy photon into two usable charge carriers, a process known as singlet fission or photon multiplication. This allows the cell to generate more electricity from the same sunlight and theoretically pushes efficiency toward 44%. The company's approach is distinguished by its compatibility with solution-processable perovskite inks. Rather than manufacturing complete solar panels, TwoPhold develops materials that can be integrated into existing perovskite production lines, including roll-to-roll printing. This strategy positions the startup as a technology partner for perovskite developers, aiming to deliver higher efficiency without adding cost to the final product. As of its public launch, TwoPhold has been in a phase of partnership and integration, working with perovskite developers to optimize the technology in real devices. The team remains small, with a mix of experienced founders and early-career researchers and interns, reflecting its startup stage. The company is registered as TwoPhold Limited in New Zealand and maintains a web presence at twophold.com.
