ABSTRACT

In this novel experiment, the performance of solar PV cell is tested under different pressure (partial vacuum condition), which is a step towards its performance improvement. The small-scale hardware is designed and developed for this setup, which contains mainly the transparent air-tight container, pressure gauge, temperature sensor, irradiation sensor, and compressor unit. In this experiment, under different vacuum condition the performance of the solar PV panel is exhibited by I-V characteristic, temperature v/s vacuum curve, voltage v/s temperature curve; current, voltage and power waveforms using digital storage oscilloscope. From this experiment, it has been observed that the partial vacuum condition affects solar panel positively. One of the key findings is that as the vacuum level is increased, eventually power generated by the solar panel is increased. In the case of -2.3039 (inHg) of pressure, the temperature decreased from 48.172–37.149°C without humidity and dust particle. In this case, the power is increased from 2.713 W to 2.876 W which is a total 6% increment in power.

摘要

在这个新颖的实验中，太阳能光伏电池在不同压力（部分真空条件）下的性能进行了测试，这是朝着提高性能迈出的一步。为该装置设计和开发了小型硬件，主要包括透明密封容器、压力表、温度传感器、辐照传感器和压缩机单元。本实验通过IV特性、温度v/s真空曲线、电压v/s温度曲线来展示不同真空条件下太阳能光伏板的性能；电流、电压和功率波形使用数字存储示波器。从这个实验中，已经观察到部分真空条件对太阳能电池板有积极的影响。一项重要发现是，随着真空度的增加，最终由太阳能电池板产生的电力增加。在 -2.3039 (inHg) 压力的情况下，温度从 48.172–37.149°C 下降，没有湿度和灰尘颗粒。在这种情况下，功率从 2.713 W 增加到 2.876 W，总共增加了 6% 的功率。
