TPV is becoming increasingly popular due to its advantages of silent power generation, higher power density (>2.5 W/cm2), reduced cost, no moving parts (thus, low maintenance costs), reaching full power in less time as compared to turbines, operating at high temperatures, and suitability for long-duration energy storage applications. This study conducts a techno-economic analysis (TEA) of a solar energy conversion (using TPV) and storage system (using phase-change materials). We optimize the levelized cost of consumed energy (LCOE) and electricity (LCOEel) using the Nelder-Mead algorithm for four scenarios (as identified in the reference study). These scenarios differ in nominal-weighted average cost of capital (WACCnom), fuel and electricity inflation rate, and capital cost factor (CAPEX) of high-temperature energy storage (HTES), power generation unit (PGU), and PV systems. We perform a sensitivity analysis that predicts a modest decrease in LCOE and LCOEel from the mean values of $0.038/kWh and $0.128/kWh, respectively. We perform a Monte Carlo uncertainty assessment and fit a probability distribution based on input variables’ historical data from the literature. The fitted probability distribution for outputs (mean, the standard deviation in brackets) is LCOE ($/kWh)—general extreme value (0.035, 0.009), and LCOEel ($/kWh)—t (0.132, 0.016). The reduced mean values for the optimized system indicate a massive potential for TPV to be economically feasible; however, the LCOEel is higher than the current average electricity price of $0.124/kWh. The box plot shows that lifetime, PV CAPEX, inflation rate, natural gas price, and WACCnom significantly impact LCOE, and future research focused on them would lead to a better adoption of TPV technology.","PeriodicalId":16781,"journal":{"name":"Journal of Photonics for Energy","volume":"30 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We measured an output power of 8.5 W with optical-to-optical conversion efficiency of 1.43% in multimode operation when the laser was exposed to an incoming solar power of 593 W at an irradiance of 900 W/m2. The YAG/Ce:Nd:YAG/YAG composite laser rod withstood the severe conditions of solar end-pumping for several hours of testing without any negative effects or degradation of laser output over time. To interpret and comprehensively analyze the experimental results, we developed a simulation model based on our experimental setup and conducted calculations with taking into account thermal population of lower laser levels. Simulation calculations show that a small deviation from a straight line in the experimental input–output dependence is a consequence of the weak influence of thermal population of the lower laser levels. To compare with recent achievements with conventional laser rods of comparable sizes and to formulate some useful recommendations when using composite crystals in future studies, we carried out additional numerical experiments taking into account possible optimizations, which do not affect in any way the thermal load on the front part of the laser rod considered in this experiment. The numerical studies demonstrate that solar-to-laser power conversion efficiency of 4.0% is achievable with a 3 mm laser rod when the solar input power is about 600 W. We also discuss the influence of rod size and thermal effects on conversion efficiency. Based on the findings of this study, we conclude that employing laser media composed of a single or multirod system with a composite structure could potentially offer an optimal solution to the thermal challenges inherent in solar-pumped solid-state lasers.","PeriodicalId":16781,"journal":{"name":"Journal of Photonics for Energy","volume":"4 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139689870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A review of around thirty experiments conducted so far is carried out, and the achieved performances are compared with those obtained in the detailed balance limit. The link between optimal cell bandgap and emitter temperature is highlighted as a function of out-of-band radiation exchange between the emitter and the cell. The analysis reveals that almost all the experimental data reported are far from power-maximizing conditions and more focused on optimizing efficiency. At high temperature, thermal management is obviously an issue and optimizing efficiency is required to minimize heat generation.

The biggest opportunities for ST-SCs lie in their integration as windows and skylights within energy-sustainable buildings or combining them with other solar cell technologies in tandem configuration. The performance of ST-SCs is mainly determined by the trade-off between the competing parameters of the capability to convert the light-to-electricity while allowing some part of it to pass through imparting transparency. Depending on the target application, the selection of ST-SCs is a tricky affair as some devices might offer high efficiency but compromise transparency and vice versa. In addition, this is again not helped by the fact that due to advancements in materials engineering, processing, and characterization, vastly different combinations of efficiency and transparency have been reported. So to quantify the performance of ST-SCs, we attempted and developed a figure-of-merit (FoM), which can be used as a tool that can help in analyzing and comparing the performance among various ST-SCs. The defined FoM focuses on the efficiency of the device, bifaciality factor, transmittance in the desired region, and that corresponding to 550 nm wavelength. Additionally, we have been shown how the proposed FoM can be correlated for tandem and building-integrated photovoltaics applications. Based on these resultant parameters, FoM is calculated and compared for different device architectures available in the literature. The proposed FoM shall serve as a meaningful guiding path to the researchers for the development of advanced ST-SCs.","PeriodicalId":16781,"journal":{"name":"Journal of Photonics for Energy","volume":"3 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139053810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
