Title: Separating the Heat from the Gap

Abstract

Increasing the conversion efficiency incident solar energy to electricity is a key goal in the solar R&D community. In this issue of Joule, a conceptual hybrid photovoltaic/thermal (PV/T) receiver design is reported by the research groups of Evelyn Wang and Gang Chen. High exergetic efficiency is achieved by absorbing below-bandgap and excessively high-energy photons as thermal energy, while allowing photons at the PV’s bandgap to pass through to the underlying cell.

Exceeding the solar cell Shockley–Queisser limit via thermal up-conversion of low-energy photons

Journal Article Boriskina, Svetlana V. ; Chen, Gang - Optics Communications

Maximum efficiency of ideal single-junction photovoltaic (PV) cells is limited to 33% (for 1 sun illumination) by intrinsic losses such as band edge thermalization, radiative recombination, and inability to absorb below-bandgap photons. This intrinsic thermodynamic limit, named after Shockley and Queisser (S–Q), can be exceeded by utilizing low-energy photons either via their electronic up-conversion or via the thermophotovoltaic (TPV) conversion process. However, electronic up-conversion systems have extremely low efficiencies, and practical temperature considerations limit the operation of TPV converters to the narrow-gap PV cells. We develop a conceptual design of a hybrid TPV platform, which exploits thermal up-conversion of low-energymore »« less

In-situ X-Ray Analysis of Rapid Thermal Processing for Thin-Film Solar Cells: Closing the Gap between Production and Laboratory Efficiency

Technical Report Toney, Michael F. ; van Hest, Maikel F. A. M.

For materials synthesis, it is well known that the material final state may not reach equilibrium and depends on the synthetic process. In particular, processes that quickly remove the available energy from the material may leave it in a metastable state and the metastability may actually impart desirable functional properties. By its very nature, Rapid thermal processing (RTP) is ideally suited to produce such metastable materials. However, metastability and the dynamics of reaching a metastable state are poorly understood, since this is best accomplished through in situ monitoring. In this regard, RTP is particularly challenging as the processing time aremore »« less

A transmissive, spectrum-splitting concentrating photovoltaic module for hybrid photovoltaic-solar thermal energy conversion

Journal Article Xu, Qi ; Ji, Yaping ; Riggs, Brian ; ... - Solar Energy

Here, a spectrum splitting, transmissive concentrating photovoltaic (tCPV) module is proposed and designed for a hybrid photovoltaic-solar thermal(PV/T) system. This module enables the system to more fully utilize the full spectrum of incoming sunlight. By utilizing III-V triple junction solar cells with bandgaps of 2.1eV/1.7eV/1.4eVin the module, ultraviolet (UV) and visible light will be absorbed and converted to electricity, while infrared (IR) light will pass through and be captured by a solar thermal receiver and stored as heat. The stored heat energy may be dispatched as electricity or process heat, as needed.Numerical analysis based on the Finite Elemental Method (FEM),more »« less

Internally-heated thermal and externally-cool photovoltaic cascade solar energy system for full solar spectrum utilization

Patent Chen, Gang ; Wang, Evelyn N. ; Boriskina, Svetlana V. ; ...

A single-stack, solar power receiver comprising both a thermal absorber layer and a photovoltaic cell layer. The stack includes an aerogel layer, that is optically transparent and thermally insulating ("OTTI"); a spectrally selective high thermal conductivity ("SSTC") thermal absorber layer; a bottom OTTI layer; and a PV cell layer. The SSTC layer includes a set of fins that substantially blocks solar radiation absorption in the band where PV cells are most sensitive. Photons with energies above or below this band block range are absorbed by the fins and the absorbed heat is conducted to pipes in the fin structure carryingmore »« less

Photoelectrochemical Hydrogen Production

Technical Report Hu, Jian

The objectives of this project, covering two phases and an additional extension phase, were the development of thin film-based hybrid photovoltaic (PV)/photoelectrochemical (PEC) devices for solar-powered water splitting. The hybrid device, comprising a low-cost photoactive material integrated with amorphous silicon (a-Si:H or a-Si in short)-based solar cells as a driver, should be able to produce hydrogen with a 5% solar-to-hydrogen conversion efficiency (STH) and be durable for at least 500 hours. Three thin film material classes were studied and developed under this program: silicon-based compounds, copper chalcopyrite-based compounds, and metal oxides. With the silicon-based compounds, more specifically the amorphous siliconmore »« less
