Reduction in material consumption is a conceptually straightforward pathway to diminish the cost of solar cells. Ultrathin solar cells particularly allow not only decrease of the cell cost, but also operation in a flexible device mode by mitigating flexural rigidity; however, they are inevitably accompanied by the degradation of their performance associated with the weak optical absorption. Accordingly, approaches to maximize the solar flux absorption in optically-thin constituent semiconductor layers are of primary research interest in photovoltaics, intending to enhance the cost-effectiveness without deterioration of the performance. In this study, versatile materials configurations are presented for high-performance semiconductor solar cells by synergistic engineering with transfer-printing-based assembly techniques and photonic nanostructures. The suggested materials designs and fabrication options indicate significant progress of realizing high performance flexible photovoltaics. |
