Recent progress of thin-film photovoltaics for indoor application

Indoor photovoltaics have attracted increasing attentions owing to their great potential in supplying energy for low power devices under indoor light in our daily life. The third generation thin-film solar cells, including dye-sensitized solar cells, perovskite solar cells and organic solar cells, have made rapid progress from the aspect of materials design to photovoltaic performance. This review provides an overview on the recent advances in the development of indoor photovoltaic technologies based on the third generation solar cells. The design principles of advanced thin-film indoor photovoltaics were also summarized according to the characteristics of indoor light and the advantages of the third generation solar cells. Finally, after summarizing the current research progress, the perspective on this topic is provided.
