A novel evacuated receiver improved by a spectral-selective glass cover and rabbit-ear mirrors for parabolic trough collector

[Display omitted] •A trough receiver with a spectral-selective cover & rabbit-ear mirrors is proposed.•Receiver efficiency can be improved at any solar irradiance or temperature.•Receiver optical loss can be reduced by 13 W per meter length receiver.•Absorber thermal loss can be reduced by 3.3–4...
