Abstract The Luminescent Solar Concentrator (LSC) consists of a transparent polymer plate, containing luminescent particles. cells are connected to one or more edges the plate. Incident light is absorbed by particles and re‐emitted. Part emitted guided towards solar total internal reflection. Since edge area smaller than receiving one, this allows for concentration sunlight without need tracking. External Quantum Efficiency (EQE) current–voltage ( I – V ) measurements were performed on LSC...
Two fibre tapering systems are tested for correspondence with the results of a simple predictive model taper shape. A travelling gas burner system is found to imitate and should reproducibly realise any shape taper, given an appropriate recipe from model.
The urgency of meeting climate targets, increasing land use competition and falling solar photovoltaic (PV) energy costs have created unprecedented opportunities for innovative deployment options. This study uses geospatial data processing to quantify the potential large-scale vertical panels along Europe's major roads railways. Factors such as geography, environmental constraints, limitations, techno-economic parameters, were carefully considered. An economic assessment is provided take...
