Beyond the ordinary

The next generation of solar technology is turning every window into a power generator. Engineers and researchers have developed transparent solar panels that look like ordinary architectural glass yet absorb energy-rich ultraviolet and infrared light to produce electricity. These innovative windows permit full visible daylight for comfort and design, while special photovoltaic layers harvest the sun’s invisible spectrum. At Hoordad Energy Ariyan, we’re proud to unveil our new transparent solar glass—a major R&D milestone that seamlessly integrates clean power into buildings without sacrificing style or function.

Next-Generation Solar Panel Efficiency Innovations

Emerging phototropic solar panels mimic sunflowers to maximize sunlight capture. For example, sunflower-inspired trackers use smart materials to bend toward sunlight and have demonstrated up to 4× more energy harvesting under oblique light compared to fixed panels. Even conventional one- or two-axis trackers boost annual yield by roughly 15–30% over static panels.

Hoordad Energy Ariyan’s phototropic arrays build on this principle with multi-axis, biomimetic actuation, pushing panel throughput well beyond standard rates. We also combine hybrid PV/thermal and bifacial designs: our panels generate electricity on both faces and capture heat between them. An ultra-hybrid PV/thermal prototype has shown ~280% more total energy (electric + hot water) on the same roof area than a conventional PV panel.

In parallel, advanced cell materials are extending efficiency limits. Tandem perovskite/silicon cells now exceed 30% efficiency, and lab-scale multi-junction cells are targeting >40% conversion. By integrating phototropic tracking, bifacial harvest, and next-gen cell chemistry, Hoordad’s panel technologies set a new high bar for solar efficiency.

Powering the Future:
Breakthroughs in Perovskite Tandem Solar Efficiency

In the quest to capture more sunlight, researchers are stacking new “perovskite” layers atop conventional silicon in tandem solar cells. Perovskite materials absorb parts of the spectrum that silicon misses, enabling dramatic efficiency gains. In labs and pilot lines, tandem cells have shattered previous records. 

A recent all-perovskite tandem design hit a 29.7% record, and industry teams have built tandems exceeding 34%.  These values approach the theoretical limits of solar materials (tandems could ultimately reach ~40–45% efficiency), suggesting a major leap beyond flat silicon’s ~30% ceiling.
