It mainly consists of photovoltaic/thermal (PV/T) collectors based on amorphous silicon (a-Si) cells, organic Rankine cycle (ORC), and inner-type heat storage unit. The PV/T collectors produce electricity directly via the cells, and the waste heat is carried away to the ORC for thermal power generation. Owing to the unique effect of thermal annealing, a-Si cells together with the ORC benefit from high temperature operation. Steady power generation is guaranteed by the heat storage unit. Compared with the conventional PV and solar ORC systems, the HSPGS can avoid or greatly reduce the usage of expensive battery, and has a much higher power efficiency. This work presents a close view of the HSPGS. Mathematic models are built and the system performance in the temperature range from 80°C to 150°C is estimated. Efficiency of about 12.5% can be achieved with a hot side temperature of 100°C. |
