Problem
Traditional silicon-based solar cells have limitations in capturing the full spectrum of solar radiation, particularly ultraviolet and near-infrared light, which restricts their overall energy conversion efficiency. This necessitates more advanced materials to maximize energy harvesting from sunlight.
Solution
SunDensity Canada develops advanced multilayered solar photovoltaic materials that combine perovskite and colloidal quantum dot (QD) technologies to capture a broader spectrum of solar radiation. By using perovskites to absorb high-energy photons from the ultraviolet and visible spectrum, and quantum dots to absorb lower-energy photons from the near-infrared and infrared spectrum, the technology enables higher energy density and efficiency compared to conventional solar cells. These materials are integrated into a tandem cell architecture and manufactured into large-format sheets using roll-to-roll processes, resulting in flexible, durable, and lightweight solar sheets. The sheets are then combined by solar panel manufacturers into a solar module by stacking the perovskite and quantum dot sheets on top of each other, and wiring them to a smart junction box for power addition.
Target Audience
The primary customers are solar panel manufacturers, particularly those focused on the rooftop market and space-constrained areas, seeking to improve profit margins through higher energy power density and lower input costs.
