Can a hybrid energy module harness energy from triboelectric devices and solar cells?

Conclusion In this paper we developed a hybrid energy module that harness energy from both triboelectric devices and solar cells simultaneously and independently, leveraging the principles of triboelectric and photovoltaic effects.

Are tengs a triboelectric or a photovoltaic device?

In most reported studies concerning photovoltaic and triboelectric effects, the design of TENGs is usually independent of the design of solar cells , , , , , because there are typically no shared components between TENGs and solar cells, leading to more complex device structure, manufacturing and application restrictions.

How can a Teng/Si hybrid solar cell be controlled?

In order to study the electrical output of this TENG/Si tandem hybrid solar cell, the voltage signals are recorded by a designed power management circuit (Fig. 5 a). Through switching S1 and S2 alternatively, TENG and Si solar cell can be controlled to study the individual energy collection and the superposition of two kinds of energies.

What is a Teng/Si tandem hybrid solar cell?

Given the compelling advantages of enhanced power output and expanded working time, this physical proof-of-concept TENG/Si tandem hybrid solar cell provides new opportunities to collect multiple energies from nature and to promote the development of weather-independent solar cells.

How efficient is a tandem hybrid solar cell?

The tandem hybrid solar cell achieves a champion efficiency as high as 22.04% under one sun irradiation, and a maximum power output of 147 μW with voltage of 37.19 V and current of 7.59 μA under one raindrop stimuli.

Can a Teng/Si tandem hybrid solar cell harvest rain energy?

Conclusions In summary, we demonstrate a TENG/Si tandem hybrid solar cell by integrating Ag/PDMS electrode with a traditional monocrystalline Si solar cell to simultaneously harvest solar energy and rain energy.
