Upconverter solar cells: materials and applications
Photon upconversion of sunlight for solar cells is reviewed and the possibilities to increase the efficiencies of the upconverter materials are discussed.
Ultra-high stacks of InGaAs/GaAs quantum dots for high efficiency solar cells
We report high-quality and ultra-high stacks of 400-layer In0.4Ga0.6As quantum dot structures. 150-stack In0.4Ga0.6As quantum dot solar cells offer good cell performance.
Thermalisation rate study of GaSb-based heterostructures by continuous wave photoluminescence and their potential as hot carrier solar cell absorbers
Thermalization loss rates are measured in antimonide heterostructures and used to evaluate practically achievable efficiencies of hot carrier solar cells
Resistive and thermal scale effects for Cu(In, Ga)Se2 polycrystalline thin film microcells under concentration
Polycrystalline Cu(In, Ga)Se2 microcells with diameter down to 7 μm have been fabricated for the first time. They show a 4% absolute efficiency increase from ×1 to ×120, and little heating up to ×1000.
About this collection
Energy & Environmental Science is delighted to present a themed-collection highlighting research from the ‘Advanced inorganic materials and concepts for photovoltaics’ symposium, held at the E-MRS 2011 Spring Meeting & Bilateral Conference on Energy, Guest Edited by Gavin Conibeer (University of New South Wales, Australia).
