Recent advances in thermophotovoltaic (TPV) power generation have produced notable gains in efficiency, particularly at very high emitter temperatures. However, there remains substantial room for improving TPV conversion of waste, solar, and nuclear (WSN) heat streams at temperatures below 1100° C. The concept of transmissive spectral control enables efficient recuperation of below bandgap photons by allowing them to transmit through the cell to be absorbed by a secondary emitter. A semitransparent TPV cell is fabricated of a thin InGaAs/InP heterojunction membrane supported by an infrared-transparent heat-conducting substrate. The device absorbs less than 1% of below bandgap radiation, resulting in a TPV efficiency of 32.5% at an emitter temperature of 1036° C. This represents an 8% absolute improvement in efficiency relative to the best TPV devices at such low temperatures. By enabling near-zero photon loss, the semitransparent architecture facilitates high TPV efficiencies over a wide range of applications.

Solar trackers and control systems prevent damage from weather events – such as hail – by orienting solar panels at optimal angles during such weather events. These angles may be achieved and managed by the physical stops of the slew drives and mechanical stop assemblies in the tracker. Control systems may trigger stowing of the solar panels during such weather events in a variety of ways, including comparing irradiance measured from the solar panels with expected irradiance.
