“…[14,27] Furthermore, micro-CPV enables the tracker integration in a module by moving internal subcomponents to continuously capture concentrated sunlight, with displacements of only a few millimeters needed. [34][35][36][37][38][39][40][41] A salient example is the integrated tracking approach from Insolight S.A. using a high acceptance double convex optic and a movable cell-plane. A measured electrical efficiency of 29% was achieved, and the technology is currently being commercially deployed.…”

The global energy market is seeing increases in the electricity demand of a couple of percentage points annually. The photovoltaic (PV) industry is also growing rapidly every year. One of the PV technologies is concentrator photovoltaics (CPV). CPV uses high‐efficiency multijunction solar cells and optics to concentrate sunlight, thereby significantly reducing the amount of semiconductor material needed. Yet, due to the high upfont manufacturing cost of CPV, it currently does not offer a competitive price against silicon PV. With this a new branch is introduced to the industry, micro‐CPV, which can be broadly explained as the miniaturization of the solar cells and optical components. The motivation for micro‐CPV is lowering the cost by decreasing the material volume and enabling new system architectures and high‐throughput manufacturing methods, while still maintaining high electrical efficiencies, taking advantage of a lower thermal load, shorter optical paths, lower resistive losses, and lower material volumes. Herein, a comprehensive review of the technological advances is presented, key synergies between micro‐CPV and other industries sharing similar challenges are identified, exemplified by micro‐light emitting diodes display manufacturing. New assembly process development in these industries will facilitate commercial adoption of micro‐CPV with continued miniaturization while driving down the cost.

The Scheffler cheval glass is a new solar concentrator design that maintains a rooted focus while only having a singleaxis tracking mechanism.This plan makes the development and activity of high-temperature sun-powered concentrators open to agricultural countries. For the present paper,the survey is performed to see better the elements and the impact of twisting or deviations from ideal conditions to describe fundamental collecting and reasonable protections.These instruments and information herd the model of new absorber mirror ideas to double hub following to least power.

“…Insolight has recently demonstrated this concept for pre-industrial modules, achieving peak 29% electrical efficiency. Another approach based on lateral displacement of two stages of planoconvex lenses designed using the simultaneous multiple surface (SMS) algorithm can theoretically achieve 500X with ±24°acceptance using a polar single-axis tracker [86][87][88][89]. Related to this concept, planar micro-tracking concepts use concentrator lenses to focus light on some micro coupling features that scatter or reflect light into a waveguide, which direct light towards the edges where the receiver cells are located.…”

Photovoltaic (PV) energy conversion of sunlight into electricity is now a well-established technology and a strong further expansion of PV will be seen in the future to answer the increasing demand for clean and renewable energy. Concentrator PV (CPV) employs optical elements to concentrate sunlight onto small solar cells, offering the possibility of replacing expensive solar cells with more economic optical elements, and higher device power conversion efficiencies. While CPV has mainly been explored for highly efficient single-crystalline and multi-junction solar cells, the combination of thinfilm solar cells with the concentration approach opens up new horizons in CPV. Typical fabrication of thin-film solar cells can be modified for efficient, high-throughput and parallel production of organized arrays of micro solar cells. Their combination with microlens arrays promises to deliver micro-concentrator solar modules with a similar form factor to present day flat-panel PV. Such thinfilm micro-concentrator PV modules would use significantly less semiconductor solar cell material (reducing the use of critical raw materials) and lead to a higher energy production (by means of concentrated sunlight), with the potential to lead to a lower levelized cost of electricity. This review article gives an overview of the present state-of-the-art in the fabrication of thin-film micro solar cells based on Cu(In,Ga)Se 2 absorber materials and introduces optical concentration systems that can be combined to build the future thin-film micro-concentrator PV technology.
