The photoelectric conversion rate of solar cells has always been one of the key factors that determine their performance. Perovskite solar cell technology, as the leader in the third generation of solar cell technology, has many advantages such as high photoelectric conversion rate and low cost, and has huge The future development potential of the industry. Four-Point Probe Tester produced by Millennial Solar can efficiently detect the resistivity and sheet resistance of ITO films deposited on solar cells, thereby helping solar cell manufacturers better ensure the photoelectric conversion rate of perovskite solar cells.

The leader of the third generation of solar cells - perovskite solar cells

Perovskite solar cells are new compound thin-film solar cells that use perovskite materials as the light-absorbing layer. Perovskite materials are the core of perovskite solar cells. Perovskite does not specifically refer to a compound containing calcium and titanium, but a material with the same crystal structure as the mineral perovskite oxide.

Perovskite crystals can be found in ultrasound machines, memory chips and solar cells.

Perovskite solar cells are solar cells that use perovskite structural materials as light-absorbing materials. They are representatives of the third generation of solar cells, including pure perovskite cells and perovskite laminated cells. Compared with crystalline silicon cells, , Perovskite solar cells have the advantages of high ultimate photoelectric conversion rate, low production cost, simple preparation process, and high flexibility. They can be widely used in photovoltaic power generation, LED and other fields, and have broad development prospects.

The development prospects of perovskite solar cells

The conversion efficiency of perovskite cells has improved rapidly. Since its invention in 2009, the conversion efficiency of perovskite solar cells has increased from only 3.8% to 25.7%. In addition, the photoelectric conversion rate of perovskite laminated cells is even expected to break through 50%,this shows broad development prospects. At the same time, perovskite crystals can also be attached to glass, which has the potential for large-scale production and is expected to become a mainstream technology route in the future, alongside TOPCon and HJT.

Conversion efficiencies of best research solar cells worldwide for various photovoltaic technologies since 1976.

Perovskite solar cells continue to make breakthroughs in reducing costs and improving efficiency. According to predictions, by the end of 2023, the photoelectric conversion efficiency of square meter perovskite solar cells is expected to reach 17% to 19%, and is expected to increase to 25% by 2030. The cost of production lines is also expected to be significantly reduced, reaching the level of 1.0~1.5 yuan/W, or even to 0.8 yuan/W for GW-level production lines and 0.6 yuan/W for 10GW-level production lines. With the continuous advancement of industrialization, perovskite solar cells have achieved remarkable results in cost reduction and growth, and their future development is promising.
