Researchers from Soochow University, Xi''an Jiaotong-Liverpool University and Egypt''s National Research Centre have developed a novel approach for making an all-weather solar cell that is triggered by both sunlight
With a TENG, solar cells could work come rain or shine (TENG) device is built to realize power generation from 2/3. both sunlight and raindrops. A heterojunction silicon (Si) solar cell is
Therefore, TENG and solar cell integrated devices are particularly suitable for working in complex outdoor environments. In Figure 7(d), a 1000 μF capacitor is working as a power store. Among the whole process, electricity is firstly

Hybrid energy harvesters based on TENGs provide a promising method to effectively use the environmental conditions for energy harvesting by combining two or more working mechanisms, generating high currents by harvesting all
We utilized a solar cell with a power density of 20.5 W/m 2 as the power source with high current but low voltage, and a TENG with a power density of 2.3 W/m 2 as the power
Triboelectric nanogenerator (TENG) has become a promising option for high-entropy energy harvesting and self-powered sensors because of their ability to combine the effects of contact
Self-charging power pack: although the hybrid energy harvesting can improve the energy efficiency to a certain extent, the energy scale of TENG still belongs to the category of microenergy, and minimizing the power consumption of the back-end management circuit is the long-term pursuit goal in this field.
Harvesting energy from ambient environment has become a promising solution to solve the energy problem of microsystems. To further increase the energy conversion efficiency or expand the application scenes of energy harvesters, hybrid energy harvesting technology based on the TENGs has been developed.
For TENG, substantial amount of energy input will be wasted through friction induced heat dissipation, especially for the high-frequency sliding motion. In this regard, it is reasonable to employ pyroelectric nanogenerator to harvest the thermal energy from the friction induced temperature fluctuation [100, 101].
The integration of TENG and PENG reduces the loss of mechanical energy in the vertical direction, and the output is improved as a wearable power supply device because the structure and materials of both kinds of devices can be designed as flexible.
As an emerging technology, TENG is developing at a rapid pace, and its ability to help wearable devices achieve passive sensing and real-time monitoring can help implantable devices function for a long time or even permanently. But there is still a long way to go to translate the idealized experimental results into applications in real practice.
