Recent advancements on Photovoltaic thermal and Greenhouse Dryer

The Homosapien's growth increases energy needs for their existence, yet the energy supplies from all major sources are restricted. Renewable energy sources such as solar energy, geothermal energy, and wind energy are viable options for fulfilling future demand without creating any harm to the environment. Photovoltaic thermal and greenhouse dryer systems allow us to utilize solar energy in a desirable form, such as heat and power. It is observed that the cell temperature and low operation hours are the primary concern for the PVT and greenhouse dryer respectively. Various innovations are identified from the literature to enhance the performance of these systems. Phase change material and a secondary heating system were integrated with the greenhouse dryer that helps to improve its operations hours even after sunset along with improvement in thermal efficiency. In the same manner, various combinations like integration of PCM, nano-particle, and packing factor were designed to the cell temperature and improve its thermal and electrical performance.
