    Abstract

    With the gradual reduction of fossil fuel and the growing environmental concerns over the climate change associated with the use of fossil fuel, renewable energy sources such as solar, wind, biomass, geothermal and hydroelectric are becoming increasingly important. In particular, solar power generation has emerged as the most rapidly growing renewable source. As a result, solar cells of different types have been intensively studied. In this special issue, 2 review articles and 2 research articles focusing on solar cells are presented. Dye-sensitized solar cells (DSSCs) are regarded as one of the most promising types due to their low-cost, transparency and relatively high conversion efficiency. Dr. Hongwei Han et al. reviewed the recent progress of materials and achievements for all-solid-state DSSCs and highlighted some representative examples. Also, in a research article, they reported a monobasal solidstate DSSCs with mesoporous TiO2 beads, and as high as 4% efficiency is achieved under air mass (AM) 1.5 illumination. Dr. Mingkui Wang et al. introduced the design and understanding of sensitizers, which are extremely important in determining the performance of DSSCs. The advances in the conception and performance of various sensitizers including ruthenium complexes, organic dyes and porphyrins are discussed. Dr. Guoli Tu et al. synthesized five 4,7-dithien-2-yl-2,1,3-benzothiadiazole (DTBT)-based conjugated copolymers with controlled molecular weight. Compared with the fluorene-based polymer, the carbazole-DTBTcopolymer showed higher short circuit current density (Jsc) and power conversion efficiency (PCE) value that was due to its better intermolecular stacking.
