“…Solar energy is available only during the daytime, thermoelectric energy is available only where there is temperature gradient, and mechanical energy is available only where there are mechanical vibrations. We have developed approaches for simultaneously harvesting solar and mechanical energy, [19,20,21] or chemical and mechanical [22] energy. These studies are developing new fields in energy research.…”

Currently, integration of energy harvesting and storage devices is considered to be one of the most important energy-related technologies due to the possibility of replacing batteries or at least extending the lifetime of a battery. This review aims to describe current progress in the various types of energy harvesters, hybrid energy harvesters, including multi-type energy harvesters with coupling of multiple energy sources, and hybridization of energy harvesters and energy storage devices for self-powered electronics. We summarize research on recent energy harvesters based on the piezoelectric, triboelectric, pyroelectric, thermoelectric, and photovoltaic effects. We also cover hybrid cell technologies to simultaneously generate electricity using multiple types of environmental energy, such as mechanical, thermal, and solar energy. Energy harvesters based on the coupling of multiple energy sources exhibit enhancement of power generation performance with synergetic effects. Finally, integration of energy harvesters and energy storage devices is introduced. In particular, self-charging power cells provide an innovative approach to the direct conversion of mechanical energy into electrochemical energy to decrease energy conversion loss.

“…The photovoltaic potential and the piezopotential are in the same direction and thus are added together. [11] The combined potential creates a stronger voltage drop between the positive (top) port and the negative (bottom) port, which drives current through an external load. Owing to the high interfacial energy barrier, electrons accumulate at the interface between the p + -nc-Si layer and top AZO electrode until the resulting potential balances the piezopotential in an equilibrium state.…”

“…Achieving these goals requires innovative and integrated methods, materials, and structures. [10,11] Herein, we present the first cascade-type transparent vibration/solar energy cell synthesized on a polyethylene naphthalate (PEN) flexible substrate. The cascade-type CHEC's monolithically-integrated two-terminal structure substantially suppresses the large interfacial electrical losses typically encountered in mechanically stacked devices.…”

“…The nanotechnology-based compact hybrid energy cell (CHEC) proposed here can individually and concurrently harvest vibrations and/or solar energies. [10,11] Various CHECs have been proposed for harvesting vibration, solar, thermal and chemical energies. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] For example, functioning CHECs made of intrinsic ZnO nanowires (NWs) and 2 organic polymer blends have been reported to harvest strain and solar energies.…”
