The advantages of perovskite cells

Compared with crystalline silicon cells, perovskite cells has the following advantages
1. High photoelectric conversion efficiency
Data show that the theoretical limit efficiency of single crystalline silicon cells is about 29%, while the theoretical efficiency of single junction perovskite photovoltaic cells can reach 31%; perovskite stacked cells, including double-junction stacked cells of crystalline silicon/perovskite, can reach a conversion efficiency of 35%, and the theoretical efficiency of perovskite triple-junction cells can reach more than 45%, so it is considered by the industry to be the next generation of mainstream photovoltaic technology.
2. Rich materials and easy to synthesize
The basic raw material of crystalline silicon cells is polycrystalline silicon, which requires a lot of energy to purify the original silicon material. The production process of perovskite cells does not require silicon materials. The raw materials required for the production of metal halide perovskites are abundant and cheap. The preparation of the precursor solution does not involve any complex process, and the purity requirements are not high. The subsequent components do not require high processing environment. The component production process does not require the processing temperature of about 1,000 degrees of crystalline silicon cells. The energy consumption in the production process is relatively low, and most links do not require a vacuum environment. At present, the electrode material accounts for the largest proportion of the cost structure of perovskite components, reaching 37%, while the material cost of perovskite itself accounts for only 5%. Perovskite components still have a large room for cost reduction in the future.
3. Short production process
Crystalline silicon cells generally require four production and manufacturing stages: silicon materials, silicon wafers, batteries, and components. This process takes at least 3 days, while the production process of titanium ore cells is simple. Glass, film, target materials, and chemical raw materials can be processed into components in a single factory within 45 minutes. The industrial chain is significantly shortened and the value is highly concentrated.
4. Rich application scenarios
Perovskite has the characteristics of light weight, flexibility, and high low-light resistance, and its downstream application scenarios are broad. Including photovoltaic buildings, power generation curtain walls, power generation stones, roof photovoltaics, mobile devices and electronic products, networked sensors, etc. With the advancement of technology, the application scenarios of perovskite are full of imagination.
