The Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP27) will take place at the Kyushu University, Japan from the 18th to the 20th of January 2027. Solar energy conversion by low-cost and efficient photovoltaic devices is steadily increased its contribution in the global demand renewable energy. Hybrid and organic solar cells were highly promising power sources due to their significant progress in efficiency and technology.  The main topics of this conference were related to material preparation, modelling and fabrication of hybrid and organic photovoltaic cells, including dye-sensitized solar cells, organic thin film solar cells, quantum dot solar cells, and solar cells. Building upon success of the previous conference in Japan, this Conference provided an excellent opportunity for scientists and engineers worldwide to exchange information and discussions on the latest developments in photovoltaics.
