Q & A

What makes perovskites potentially more efficient than traditional silicon solar cells?

Perovskites can capture a wider range of the light spectrum than silicon, potentially breaking the theoretical efficiency limit of 29% for silicon cells. They can also be tuned to absorb light that silicon PVs miss, making them more versatile and effective in harnessing solar energy.

Why have perovskites not been widely used in the market despite their high efficiency?

The primary issue with perovskites is their durability. They tend to degrade quickly in real-world conditions due to exposure to heat, moisture, oxygen, and UV rays, making them less reliable compared to silicon cells that can last over 25 years.

What recent advancements suggest that 2024 could be the year for perovskites?

Recent breakthroughs in perovskite research have improved both their efficiency and durability. For example, Oxford PV has developed tandem cells with a claimed lifespan of 25 years, and they have been testing them in outdoor environments for stability. Their partnership with the Fraunhofer Institute has also led to a record 25% efficiency for a perovskite solar module.

What are tandem solar cells, and how do they work?

Tandem solar cells are a combination of perovskite and silicon layers that work together to capture more sunlight than either could on its own. The perovskite layer is tuned to absorb light wavelengths that silicon cannot, resulting in higher overall efficiency while maintaining the same footprint as a traditional silicon panel.

How do recent developments by the King Abdullah University of Science and Technology (KAUST) contribute to perovskite progress?

KAUST researchers are focusing on optimizing the architecture of perovskite cells, specifically in P-I-N structures that enhance charge carrier mobility. Their novel design, which includes improved bonding ligands, has achieved a power conversion efficiency of 25.63% and shown durability under high temperatures.

What are the benefits of semi-transparent perovskite solar cells, as developed by the Korea Institute of Energy Research (KIER)?

Semi-transparent perovskite cells can be used in applications like solar windows and bifacial panels. KIER's cells, which include a metal oxide layer for added protection, have achieved a high efficiency of 21.68% and maintained 99% of their initial efficiency over 240 hours, making them highly promising for building-integrated solar solutions.

What challenges remain for perovskite solar cells to become a mainstream technology?

The main challenges are proving their long-term stability and durability under real-world conditions. While many advancements have been made, the longevity of these cells outside of controlled lab environments remains a concern, and further testing is needed before widespread adoption.

Why did CubicPV shift its focus from silicon wafers to tandem perovskite cells?

CubicPV decided to focus on tandem perovskite cells due to their potential for greater efficiency gains and the promise of overcoming the durability issues. The company abandoned its planned silicon wafer factory, suggesting confidence that perovskites represent the future of solar technology, despite the uncertainties.

What makes Oxford PV's progress particularly noteworthy in the field of perovskite solar cells?

Oxford PV claims to have developed perovskite tandem cells with a lifespan that can rival silicon panels, achieving only a 1% efficiency loss in the first year and minimal decline thereafter. This progress, alongside their plan to start commercial production in 2024, positions them as a leader in moving perovskites from lab to market.

Why is increasing the efficiency of solar panels significant, as illustrated by the example in the script?

Increasing solar panel efficiency allows for more energy generation from the same physical space. For example, improving panel efficiency from 21.6% to 25% could mean generating 15% more energy annually. This reduces the number of panels needed to meet energy goals, potentially lowering costs and the space required for installations.
