Solar Windows
A New Class of Transparent Photovoltaics
Traditional “transparent” solar attempts have relied on laser cut opaque materials, organic photovoltaics, or early-stage perovskites. These are all approaches that either aren’t inherently transparent, reduce power output, degrade over time, are unstable or cannot be manufactured at scale.
Enkara’s Solar Windows are Different
Enkara’s technology is built on proven cadmium-telluride (CdTe) semiconductor physics, engineered into a transparent architecture, and paired with advanced optical coatings to increase light transmission and overall performance. This combination merges durability, manufacturability, and optical clarity in a way that no prior technology has achieved.
Performance Advantages
Enkara’s Solar Windows are built on material platforms with decades of demonstrated real‑world durability, providing long‑term stability consistent with photovoltaic technologies with reliably exceeding twenty years. Our transparent photovoltaic architecture is engineered for compatibility with existing large‑area coating equipment used by major window manufacturers and established thin‑film deposition processes, enabling straightforward integration into current production workflows.
By combining advanced semiconductor design with engineered optical coatings, our Solar Windows deliver a balanced approach to transparency and energy generation while maintaining the optical quality expected of architectural glass. This foundation supports consistent manufacturing, predictable performance, and a clear path toward scalable commercial deployment.
A Pathway to Energy-Producing Buildings
Enkara’s Solar Windows eliminate the microscopic metal grids and conductive overlays that make traditional photovoltaic devices opaque, allowing our transparent architecture to function as true window glass while still generating electricity.
Because our materials are based on refined CdTe semiconductor physics, they maintain performance across a wide range of angles, making them far better suited for vertical installations than silicon, which loses much of its efficiency when sunlight is not perpendicular.
By combining full transparency with angle‑tolerant power generation, Enkara has created a window solution that can deliver meaningful on‑site energy and achieve a return on investment in as little as twelve to twenty‑four months without requiring tax credits or government subsidies.
