Abstract

The temperature of Photo-Voltaic (PV) cells which increases when getting high radiation levels during the mid-day can reduce the efficiency of PV cells. This is a detrimental characteristic of producing electrical energy in a solar power generation system. The study objective is to improve cooling techniques in PV cell installations, particularly to maintain the temperature condition of the system working at optimal performance. The research was carried out using an experimental method by conditioning the PV module under vacuum pressure (pressure < 1 bar). A casing is designed in such a way as to allow a PV cell to be in a negative condition with sunlight still being able to penetrate it on the top side by using a material that is translucent and can withstand negative pressure. Nitrogen gas is filled into the casing before being vacuumed at negative pressure. The test is carried out outdoors with the actual conditions of solar radiation and ambient air temperature. Parameters for measuring pressure, temperature, radiation level, voltage, and current as well as electric power use an instrument equipped with a data logger that measures in real-time with a high degree of accuracy. The type of PV module employed in the test consists of two mono-crystal PV modules. One PV was treated with vacuum pressure while the other was left under normal conditions. The test results show that the temperature of the PV cell in a vacuum has a slow increase, where the maximum temperature is 30 °C even though it gets a high level of radiation during the day. There is also a difference in efficiency between those treated with negative pressure compared to PV cells that was not treated.
