Solar cells based on the photovoltaic effect are an effective method to convert solar energy into electricity. It has become attractive to find solar cell technologies which exhibit lower manufacturing costs by utilizing inexpensive and abundant materials. Some additional advantages conveyed by organic solar cells are that they are lightweight and flexible and allow for scalable material production and cost effective roll-to-roll coating and printing techniques. Efficiency of >10% was disclosed in small area solar cells with various device architectures, which indicated the rapid progress over the last several years and the great potential of organic solar cells as an alternative source of energy. In order for organic solar cells to fully mature from research and development into cost effective products, solar cell technology at a small size needs to be realized at a large scale. And for this, it is highly important to develop new conjugated polymers and understand the fundamental working mechanism of the materials. In the presentation, we developed new conjugated polymers for large-area solar cell technologies and studied the effects of conjugated polymers on solution processing and photovoltaic performance in large area organic solar cells.
