Problems solved by technology

The traditional photoelectric receiving target surface packaging process is to directly weld the single laser battery on the photoelectric receiving target surface substrate through surface mount technology (SMT) and other processes. In the area array packaging process, the gap between the battery and the battery is relatively Large (generally 18~25% of the photoelectric receiving target surface), resulting in a small effective area of ​​photoelectric cells on the photoelectric receiving target surface, which seriously affects the overall photoelectric conversion efficiency of the photoelectric receiving target surface

Description

technical field [0001] The invention relates to the field of laser wireless energy transmission, in particular to an array-focused laser energy transmission photoelectric receiving device. Background technique [0002] Laser wireless energy transmission technology uses high-energy light beams as energy carriers, and uses efficient electro-optic and photoelectric conversion to realize non-contact energy supply to remote specific equipment. Compared with electromagnetic coupling, magnetic resonance energy transmission, etc., laser wireless energy transmission can achieve a longer transmission distance; compared with microwave wireless energy transmission, laser wireless energy transmission devices are smaller in size and weight, and have higher conversion efficiency. For static and dynamic energy transfer to remote small targets. At present, Europe, the United States, Japan, etc. have conducted a lot of research on laser wireless energy transmission. [0003] Since the optic...
