Conclusion In summary, we have proposed a novel strategy to design and construct an STEG device by the use of the high-performance Cu 1.5 Mn 1.5 O 4 spinel-type PTC material to capture and convert solar energy into electrical energy, and subsequently coupling the STEG device and the SC device to achieve electrical energy storage and utilization.

To make full use of the solar energy, an important way is to produce the devices of tandem structure that could cover the entire spectrum and absorb the photon energy as much as possible.
A solar tube integrating the photo-electric and photo-thermal conversion is demonstrated. The titanium having small plasma frequency is selected to enable wide absorption of photon energy for thermal conversion. A sandwiched membrane of high transparency and conductivity is developed for tubular solar cells. 1. Introduction
