Problems solved by technology

However, there are still obvious defects in this technology: for example, the conversion efficiency of photovoltaic panels is still relatively low, and the conversion efficiency of photovoltaic panels will be greatly affected when the temperature changes; due to the high energy density of the laser, it is easy to use under long-term laser irradiation The temperature of the photovoltaic panel increases, which reduces the photovoltaic conversion efficiency, and the photovoltaic panel is more likely to be damaged under long-term high-intensity laser irradiation
