Indium – A key component in indium tin oxide (ITO) coatings, used for transparent conductive layers that improve electrical performance and light transmission in solar cells.
Will liquid-crystal displays and photovoltaic panels drive indium future demand?
Indium demand is expected to significantly increase due to its use in liquid-crystal displays and photovoltaic panels. The results show that these applications could increase indium demand by 2.2–4.2, 2.6–7.0, and 6.8–38.3 times for the 8.5, 14, and 60 TW scenarios, respectively. This could lead to potential shortages as early as the next decade.
Copper indium gallium selenide (CIGS) thin-film solar panels are known for their high efficiency, flexibility, and lightweight design, making them a key alternative to traditional crystalline silicon (c-Si) solar cells.
What role will electronics and photovoltaic industries play in indium demand?
Indium demand in the electronics and photovoltaic industries is crucial. We assess their indium demand using three cumulative photovoltaic capacity scenarios (8.5, 14, and 60 TW by 2050) with different dominant photovoltaic sub-technologies.
What is Photovoltaic Glass?
Photovoltaic (PV) glass stands at the forefront of sustainable building technology, revolutionizing how we harness solar energy in modern architecture. This innovative material transforms ordinary windows into power-generating assets through building-integrated photovoltaics, marking a significant breakthrough in renewable energy integration.
The active photovoltaic layer, responsible for converting solar energy into electricity, is composed of semiconductor materials. In crystalline silicon-based PV glass, this layer contains ultra-thin silicon wafers, while thin-film technologies utilize materials such as amorphous silicon, cadmium telluride, or copper indium gallium selenide (CIGS).
How efficient is PV glass?
In optimal conditions, modern PV glass installations typically achieve conversion efficiencies ranging from 5% to 15%, with high-end products reaching up to 20% efficiency. Real-world performance data indicates that a standard square meter of PV glass can generate between 50-200 kilowatt-hours (kWh) annually.
