Solar energy has been considered as a clean, renewable, and sustainable energy and an electrical energy, which is the most safe and convenient energy form to live daily life, has been obtained from the direct and indirect products of it. Solar cell is a device that directly generates electricity from solar light energy so intensive studies have been done to develop highly efficient solar cells with low cost to expand its usage for power generation. Although crystalline Si solar cells have been successfully commercialized for power generation, their power generation cost is still more expensive than the fossil fuels due to expensive vacuum process. Hence, the development of cheap solution processable next-generation solar cells has been studied for several decades. Recently, metal halide perovskite has considered as a promising candidate for next-generation solar cell because of their excellent properties such as strong absorptivity, convenient bandgap tunability, small exciton binding energy and solution processability. Here, I would like to share research trends of metal halide perovskite solar cells and what we have studied.
