In this research work, we have synthesized nanocrystalline Bi 2 Te 3 thin films for photoelectrochemical (PEC) solar cell application by potentiostatic electrodeposition method on stainless steel substrates. Subsequently films were irradiated with electron beam irradiation (EBI) of energy 4.5 MeV at various doses of irradiation ranging from 10 to 50 kGy. The experimental results showed that synthesized Bi 2 Te 3 thin films having polycrystalline nature and rhombohedral crystal structure with momentous morphological digression through various doses of irradiation. The electrochemical active surface area (ECSA) and photoelectrochemical (PEC) performance of Bi 2 Te 3 thin films were improved well at irradiation dose of 40 kGy. The calculated values of photoconversion efficiency and fill factor for Bi 2 Te 3 thin film were found to be 0.1837% and 0.5383, respectively. The values of photoconversion efficiency and fill factor of same electrode before irradiation have values 0.0987% and 0.3979, respectively. The enhancement in efficiency and fill factor due to EBI were found 53% and 74%, respectively. The enhancement in PEC properties is due to increased active surface area of the Bi 2 Te 3 films after irradiation dose. The results showed that, EBI are capable to strengthen the quality of electrode for PEC solar cell application.

“…Its melting temperature is about 92 • C, which is why it is suitable for cooking or for heating water which is near to our target range of 95-97 • C. The latent heat of potash alum is about 184 kJ/kg, which is very high compared to rest of PCMs. Potash alum is a PCM with exceptional stability behavior [29]. Table 3 shows the characteristics of the potash alum and its suitability as a phase change material.…”

Renewable energy resources like solar energy, wind energy, hydro energy, photovoltaic etc. are gaining much importance due to the day by day depletion of conventional resources. Owing to the lower efficiencies of renewable energy resources, much attention has been paid to improving them. The concept of utilizing phase change materials (PCMs) has attracted wide attention in recent years. This is due to their ability to extract thermal energy when used in collaboration with photovoltaic (PV), thus improving the photoelectric conversion efficiency. In this paper, the objective is to design and fabricate a novel thermal energy storage system using phase change material. An investigation on the characteristics of Potash Alum as a phase change material due to its low cost, easy availability and its usage as an energy storage for the indoor purposes are taken into account. The use of a latent heat storage system using phase change materials (PCMs) is an effective way of storing thermal energy and has the advantage of high-energy storage density and the isothermal nature of the storage process. In the current study, potash alum was identified as a phase change material combined with renewable energy sources, that can be efficiently and effectively used in storing thermal energy at compartively lower temperatures that can later be used in daily life heating requirements.A parabolic dish which acts of a heat collector is used to track and reflects solar radiation at a single point on a receiver tank. Heat transfer from the solar collector to the storage tank is done by using a circulating heat transfer fluid with the help of a pump. The experimental results show that this system is capable of successfully storing and utilizing thermal energy on indoor scale such as cooking, heating and those applications where temperature is below 92 °C.
