摘要：

Solar energy provides limitless resource for human being to address the terawatt energy challenge. The ideal photovoltaic (PV) technology needs to be earth abundant, non-toxic, and very low cost etc. Scientists have long dreamed of printing solar cells like newspaper, and can apply to any surface to generate electricity.

Solution processed solar cell based on organic polymer (Macromolecule) and organometal halide hybrid perovskites are both promising candidates for printable PV technologies. The advantages include low material cost, low temperature fabrication and their compatibility with printing/coating processes (roll-to-roll), high material utilization etc. They also provide attractive properties like flexibility, light weight, and transparency.

In this talk I will present a few recent works on polymer solar cell, perovskite single crystal & device, and perovskite light emitting diode （聚合物太阳能电池、钙钛矿单晶器件、钙钛矿发光器件）. The R&D challenges & opportunities on printable solution process solar cell as viable PV technology will be discussed.
