This document summarizes research on hot solar cells. Hot solar cells aim to address current limitations in solar energy like size and efficiency. Unlike conventional photovoltaic cells, hot solar cells convert sunlight to heat using an absorber-emitter material and then convert that heat back to light. This allows them to produce more energy using less space. While initial statistics show hot solar cells could be twice as efficient as today's models, they remain limited by still being in the research and development phase with high initial costs.

2. ABSTRACT
• IN RECENTTIMESTHE SHIFTTOWARD CLEANER AND RENEWABLE
ENERGY OVERTHE NON-RENEWABLE ENERGY IS FASTERTHAN EVER
BEFORE
• THUS LEADINGTO A BOOM INTHE SOLAR ENERGY INDUSTRY. ALTHOUGH
SOLAR ENERGY IS USED MORE COMMONLY NOW IT IS STILL LIMITED BY
SOME FACTORS SUCH AS SIZE AND EFFICIENCY.
• HOT SOLAR CELLS ISTHE SOLUTIONTOTHIS PROBLEMAS ITS OPERATION
ALLOWS ITTO PRODUCE MORE ENERGY USING LESS SPACE COMPAREDTO
THETODAYS CONVENTIONALSOLAR ENERGY SYSTEMS.
• HOT SOLAR CELLS ARE CURRENTLY MAINLY LIMITED BYTHE FACTTHAT IT
IS STILL IN THE RESEARCH AND DEVELOPMENT PHASE.

3. INTRODUCTION
• What is a solar cell? • WORKING OF SOLAR CELLS
REF: (1)

4. CURRENT STATE OF SOLAR POWER INDUSTRY
• Market is exploding
• The cost of conventional solar energy is starting to drop .
• R&D is now focussing of reducing the area taken by solar
panels and increasing efficiency.
• The industry has become very profitable also.
• The latest breakthrough in this field is what is named as ” HOT
SOLAR CELLS”

6. WORKING OF HOT SOLAR CELL
• It is different from the
conventional photovoltaic cell
such that it covers more of the
light spectrum.
• This technology converts sunlight
into heat and then the heat back
into light
• This process is done by a
concentrated type material called
an “ABSORBER-EMITTER.”REF [2]

7. ADVANTAGES
• Initial statistics suggest it is twice as efficient as today’s
models
• It covers less surface area
LIMITATIONS
• It is still in research phase.
• The current predicted maximum efficiency is ~ 63%
• Initial cost is very high.
