AI Technical Summary

Technical Problem

The low light transmittance of the tunneling layer in traditional perovskite/crystalline silicon solar cells leads to light reflection and absorption losses, affecting photoelectric conversion efficiency. At the same time, the lateral conductivity causes electron-hole recombination losses, and the cells are not stable enough in extreme environments.

Method used

An intrinsic heterojunction tunneling layer using a mixture of N-type and P-type SAMs was prepared by solution method to form a three-dimensional interpenetrating contact network on a crystalline silicon bottom cell, thereby optimizing the tunneling layer performance, reducing light absorption loss and suppressing lateral charge recombination.

Benefits of technology

It significantly improves photoelectric conversion efficiency and stability, enhances light transmittance, reduces non-recombination loss, and extends service life, making it suitable for space photovoltaic applications.
