Traditional pest control will choose pesticides to kill insects, but they slowly find that pesticides are used more, and pests also produce antibodies, so that not only the insecticidal effect of crops will decline, but also the quality of soil and crops will be affected by pesticides.

Sunlight is the main source of energy for solar garden lights, so the duration and intensity of sunlight directly affects their charging efficiency. On clear, sunny days, solar garden lights are able to fully charge and ensure a long lighting time at night. However, in rainy, hazy or cloudy weather, the sunlight is blocked or scattered, resulting in lower charging efficiency and a correspondingly shorter light-up time. In addition, extreme weather such as heavy snow and severe cold may also affect battery performance and discharge efficiency, further reducing the lighting time. To cope with these effects, solar garden lights are usually equipped with an intelligent control system that can automatically adjust the working mode according to the weather conditions, such as reducing the brightness or extending the charging time, in order to maximize the lighting time.

It was learned from Nankai University that the team of Professor Chen Yongsheng of the school made a breakthrough in the research of organic solar cells, which made the conversion efficiency of organic solar cells reach 17.3%.

Researchers at the University of British Columbia have discovered a new and cheap way to turn sunlight into energy with solar cells built with bacteria.
