Solar energy technology is one of the favourable alternatives in providing electricity for houses and low-speed vehicles. Due to the elevated environment temperature cause by global warming, the conversion efficiency of photovoltaic (PV) cells has decrease tremendously. The aim of this project is to develop a novel PV cell with impregnated phase-change material (PCM), which has the capability of absorbing heat radiated and generated into the cell as the form of latent heat, while maximising the conversion efficiency of a multi-crystalline Si cell with improved thermal and optical properties which converts electricity at low cell temperature. The impregnated PCM acts as an absorber that takes in heat from both the radiation from the Sun and generated from energy conversion. The heat absorbed are stored within the PCM through melting process, i.e. the heat is stored as the latent heat of fusion for the PCM. The transition of phase from PCM provides different thermal and optical properties for the cells, taking in the abundance of heat and light energy from the Sun and transform them into useful energy. The PCM-in-PV project covers a wide range of discipline, such as materials engineering, chemistry, physics, energy, mechanical and chemical engineering.

太阳能技术是为房屋和低速车辆提供电力的有利选择之一。由于全球变暖导致的环境温度升高，光伏（PV）细胞的转化效率大大降低。该项目的目的是开发具有浸渍相变材料（PCM）的新型PV细胞，该细胞具有吸收热辐射并作为潜热的形式引入细胞中的热量，同时最大程度地将多晶体的SI SI细胞的转换效率借助高电池温度转换为电能，从而最大程度地提高多晶体的SI SI细胞的转化效率。浸渍的PCM充当吸收器，从太阳的辐射中吸收热量并通过能量转化产生。通过熔化过程将吸收热量的热量存储在PCM中，即将热量作为PCM的融合热量存储。相位从PCM的过渡为细胞提供了不同的热和光学特性，从而吸收了来自太阳的热量和光能量，并将其转化为有用的能量。 PCM-IN-PV项目涵盖了广泛的纪律，例如材料工程，化学，物理，能量，机械和化学工程。
