Perovskite solar cells are flexible, affordable, and fit modern needs. They are changing how we use renewable energy.
Perovskite solar cells are easier to make than silicon ones. Silicon cells need high heat and complex machines. Perovskite cells use lower heat, under 150°C. This saves energy and is better for the planet.
These cells can be made using liquid methods like spin coating. Spin coating spreads liquid perovskite onto a surface. It’s simple and costs less money. Another way is vapor deposition, which layers materials neatly. These easy methods help make more cells without big problems.
Making these cells has improved over time. From 2014 to 2019, efficiency grew from 17.9% to 25.2%. Between 2019 and 2024, it only grew 1.5 points, reaching 26.7%. The best cell efficiency now is 27.0%. Modules could reach 25% efficiency soon if losses are reduced. In 4–5 years, 20% efficiency with 90% production success is likely.
Perovskite solar cells can be made on different surfaces. They work on glass, plastic, or metal. This makes them useful for flat panels or curved designs. For example, they can go on building walls or car roofs.
These cells are also lightweight and portable. Imagine solar panels you can roll up or fold. Perovskite materials stick well to surfaces without losing power. This makes them easy to use and build. Manufacturers can pick surfaces based on needs, not just silicon wafers.
Making perovskite solar modules costs less. They cost about $0.57 per watt, cheaper than many others. Their electricity cost is 18–22 cents per kWh. This makes them a good choice for renewable energy projects. Their low cost, flexibility, and easy production make them a game-changer in solar power.
Perovskite solar cells have trouble staying stable over time. They are easily affected by moisture, heat, and sunlight. Water can break down the perovskite layer, ruining the cell. Changes in temperature cause stress, making the cell weaker. Sunlight can damage the material, leading to faster wear. These problems make it hard for the cells to last long, especially outdoors.
Scientists are trying to make these cells more durable. They add special materials to protect against water damage. Coatings and covers help shield the cells from harm. Changing the materials inside the cells can also make them stronger. For example, using 2D structures or inorganic layers improves stability. Some tests show these cells can last over 20,000 hours in controlled settings. But most still don’t last long, with many working less than 2,000 hours.
Perovskite cells use lead, which is harmful to the environment. Lead can leak into the ground and cause pollution. Even tiny amounts of lead are dangerous, especially for kids. Studies show that lead from these cells can contaminate soil. This makes it important to fix this problem before using these cells widely.
Researchers are looking for better, safer materials to replace lead. Metals like tin and bismuth are being tested as options. These new materials aim to keep the cells efficient but less toxic. Rules about how much lead can be used are also being made stricter. By using safer metals, solar cells can become more eco-friendly.
Making perovskite cells in large amounts is not easy. It’s hard to keep the same quality and performance when producing many. Differences in materials can lower efficiency and raise costs. Problems with design, like poor electrodes, can also cause failures. These issues make it tough to match lab results in big projects.
Selling perovskite cells is still a new idea. Stability problems, like quick damage from sunlight, are a big issue. Rules for making and using these cells are still unclear. Lead in the cells also needs careful handling and disposal. Despite these problems, companies and researchers are working together. They are finding ways to make production easier and increase adoption.
To make perovskite solar cells, you first create perovskite compounds. These are made by mixing halide salts with organic or inorganic cations. Crystallization is key to making the cells work well. The best temperature for crystallization is 70 °C. This helps form the right perovskite structure. The crystal sizes range from 23.67 nm to 55.79 nm. Bigger crystals help the cell absorb more light. Keep the annealing temperature below 110 °C to avoid forming PbI₂, which lowers performance. Also, limit annealing time to under 30 minutes to improve crystal quality.
Picking the right substrates and electrodes is very important. Glass, plastic, and metal are common choices because they work well with perovskite materials. Transparent conductive oxides like ITO or FTO are used as electrodes. These let light pass through while carrying electricity. Good materials help collect and move charges, making the solar cells more efficient.
Spin coating is a popular way to make perovskite solar cells. In this method, a liquid solution with perovskite is spread on a spinning surface. The spinning spreads the liquid into a thin, even layer. This method is simple and cheap, great for making many cells. But problems like tiny holes and slow crystallization can affect quality. Sequential deposition gives better control but may cause uneven surfaces.
Vapor deposition methods, like TVD and CVD, offer more precise control. TVD creates smooth surfaces with large crystals, improving efficiency. CVD is reliable and works well for large-scale production. These methods make high-quality films, perfect for advanced solar cell uses.
| Fabrication Method | Benefits | Problems |
|---|---|---|
| One-Step Deposition (OSD) | Easy to do | Tiny holes, slower crystallization |
| Sequential Deposition (SDM) | Better control over film quality | Uneven grains, rough surfaces |
| Thermal Vapor Deposition | Smooth surfaces, large crystals | None |
| Chemical Vapor Deposition | Reliable for large production | None |
Making many perovskite solar cells needs consistent quality. Differences in material layers can lower efficiency. Using vapor deposition methods can help keep layers even. Advanced tools can check film thickness and quality during production.
Defects like tiny holes and uneven crystals can hurt performance. To fix this, improve the manufacturing process. Control the crystallization temperature and annealing steps to reduce defects. Use high-quality materials for each layer to get better results. Solving these problems helps make more reliable and efficient solar cells.
