Developing clean energy plays a central role in the sustainable development of human society. Solar energy is one of the most promising energy sources in replacement of conventional used fossil fuels. However, the daily and seasonal fluctuations in weather limit solar cell's applications. Integrating the solar cell with other kinds of energy harvesters in one device is a possible solution. Triboelectric nanogenerator (TENG) originating from Maxwell's displacement current is a new type of energy harvesters. Due to its advantages of light-weight, low-cost, and easily fabricated, TENG attracts worldwide attention in the past years. In the present work, a flexible hybrid energy harvester is designed and fabricated based on quantum dots (QDs). This device consists of a PbS-QD solar cell part and a polydimethylsiloxane (PDMS) based TENG part, which can harness both, solar and mechanical energy from ambient environment to generate electricity. GISAXS measurements are used to characterize the bending stability and morphology changes of the mesoscale structure.
