PV glass integrates solar cells into its structure, allowing it to capture sunlight and convert it into electricity. Unlike traditional solar panels, this glass can be transparent or semi-transparent, making it suitable for use in windows, facades, roofs, skylights, and other. . Photovoltaic glass technology represents a significant advancement in the realm of renewable energy, especially in the integration of solar energy generation with architectural elements.

Scientists at the Korea Institute of Energy Research (KIER) have developed a CIGS solar cell with ultra-thin glass (UTG), an emerging substrate known for its exceptional flexibility and stability. The device uses a cadmium-free buffer layer made of zinc oxide and magnesium oxide, instead of cadmium sulfide. This emerging substrate is known for its superior flexibility and stability, which. . The development of lightweight and flexible photovoltaic devices is highly desirable for integration in new applications and to reduce the manufacturing cost of modules. With a thickness of 200µm or less, it is exceptionally lightweight, and at under 100µm, it can be rolled up, enabling roll-to-roll processing for improved delivery efficiency. Thin-film solar cells are typically a few nanometers (nm) to a few microns (μm) thick–much thinner than the. .

What is a UTG & how does it work?
The UTG is specifically designed for use in space applications such as a cover glass for PV whereby it is laminated atop of the solar cells. Its cerium content provides protection from high energy radiation.
Can cadmium-free solar cells be used on ultra-thin glass?
The new cell concept was introduced in the study “ High-efficiency cadmium-free Cu (In,Ga)Se 2 flexible thin-film solar cells on ultra-thin glass as an emerging substrate,” published in the Journal of Alloys and Compounds.
Is ultra-thin glass a suitable substrate for CdTe solar cells?
Flexible metallic and polyimide foils are frequently used, but in this work an alternative substrate with attractive properties, ultra-thin glass (UTG) has been employed. CdTe solar cells with average efficiency reaching 14.7% AM1.5G efficiency have been produced on UTG of 100 μm thickness.
Why is ultra-thin glass used as a flexible substrate for CIGS technology?
Ultra-thin glass is used as a flexible substrate for the CIGS technology. The Young's moduli of Mo and CIGS layers are measured by nanoindentation. The reported values are used to calculate the strain induced in CIGS in flexion. The strain is calculated for cells made on ultra-thin glass and on polyimide. Cu (In, Ga)Se 1. Introduction
The double glass makes bifacial panels stronger. They can handle bad weather, water, and rust better. Only the front side takes in. . There has been a noteable shift from the initial single-facial single-glass modules to bifacial double-glass modules. Double-glass modules, with their performance in the face of salt mist, high temperatures and high humidity, have won the market's favour. In a feature article for PV Tech Power (Q3 2025), David Devir, principal engineer for VDE Americas, looks at the origins of today's supersized PV module glass problem and considers. . By encapsulating solar cells between two layers of glass, these modules offer unparalleled durability and efficiency.
