The core idea of the Topcon technology lies in the fact that passivation films are applied to both the positive (front surface) and negative (back surface) surfaces of the photovoltaic cell during the fabrication process, and these films play a key role in reducing electron-hole complex losses, improving electronic conductivity, and inhibiting surface reactions.

In the process, firstly, a layer of amorphous silicon or microcrystalline silicon film is coated on the front and back surfaces of the cell, respectively, by methods such as physical vapour deposition (PECVD). These films have excellent electronic conductivity and passivation properties, which can effectively reduce the surface compounding phenomenon of carriers. In addition, by forming a special oxide layer called "tunnel oxide" on the front surface of the cell, the collection and transport of carriers can be further enhanced, thus improving the efficiency of the cell.

The advantage of the Topcon technology is that it integrates the optimisation of the performance of the positive and negative surfaces through the design of the double-sided passivation, which significantly reduces the loss of electrons and holes from the complex on the surface. This helps to improve the efficiency of PV cells and provide more stable performance, especially in high temperature environments.
