    Photovoltaic is one of the most promising technologies among renewable energies, and there is a strong desire for the further spread of photovoltaic as a primary source of electricity and the development of new applications. Based on the empirical results, new applications and future vision of photovoltaic will be explained, focusing on solar carport, wall-mounted photovoltaic, and agri-voltaic.

    We need to rush into the international standardization of the performance of VIPV. IEC TC82 PT600 and WG2 group carry out the standardization discussion. This work covers the scientific aspects behind the standardization. It consists of three layers: (1) Performance testing VIPV or curved PV modules by reproducible measurements; (2) Outdoor performance validation and correction modeling; (3) Energy rating. Unlike other PV installations, the relative position of the sun and its shading objects quickly and frequently moves so that the repeatable evaluation of the performance of VIPV was challenging. As a result of scientists and testing engineers worldwide, (1) we could develop a new testing protocol for the curved PV modules, (2) we observed the different performances in the curved photovoltaic modules and succeeded in reproducing in a simple numerical model, and (3) we developed Excel-level calculation methods for shading and partial-shading impact to irradiation onto photovoltaic modules on vehicles.

    The lack of attractive n-type thermoelectric materials greatly restricts their applications because most high-performance materials are p-type conductors, such as the kesterite compound Cu2ZnSnS4. This study reports high-quality n-type kesterite (Cu1−xAgx)2ZnSnS4 (CAZTS) single crystals that exhibit a record high dimensionless figure of merit value of 1.1 at approximately 800 K, primarily owing to Ag alloying, cation compositional optimization, and intrinsic low thermal conductivity. An n-type CAZTS-based single-leg device was fabricated using a Mo-barrier layer. The device exhibited a thermoelectric conversion efficiency of 3.4% at a temperature gradient of 473 K. This study provides insights into developing thermoelectric modules using environmentally friendly kesterite materials.
