START WITH THE SCIENCE
Eight routes into photovoltaics.
Brief introductions for students, researchers and industry visitors. Open each card to discover questions worth investigating.
01
Advanced silicon solar cells
Passivation · contacts · collection
Crystalline silicon photovoltaics benefit from reduced recombination, improved passivating contacts and optical management. TOPCon, heterojunction and back-contact describe different architectural features.
What should I investigate?
Compare Voc, Jsc, fill factor, temperature coefficient and bifacial response. Distinguish cell measurements from module ratings.
02
Perovskite solar cells
Absorber · interfaces · stability
Metal-halide perovskites offer tunable absorption and processing routes. Ionic redistribution, interface recombination and environmental sensitivity influence performance. Perovskites can be hybrid or all-inorganic.
What should I investigate?
Report composition, area, scan direction/rate and stabilized maximum-power output. Evaluate encapsulation and operational aging; J–V hysteresis alone does not establish a mechanism.
03
Tandem & multijunction devices
Complementary absorption
Stacked absorbers with different bandgaps use more of the solar spectrum. Two-terminal tandems require current matching; four-terminal configurations allow separate electrical operation.
Thin absorbers and scalable deposition enable device architectures different from wafer silicon. CdTe and CIGS have distinct material properties and manufacturing requirements.
What should I investigate?
Study absorber quality, contacts, composition, band alignment, module uniformity and long-term degradation.
05
Organic photovoltaics
Donor–acceptor materials
Organic semiconductors absorb light and form excitons. Charge separation, blend morphology and selective contacts influence collected current and device stability.
What should I investigate?
Compare J–V and EQE under stated illumination. Indoor and outdoor efficiencies require different spectra and cannot be directly ranked.
06
Dye-sensitized solar cells
Dye · oxide · redox transport
A sensitizer absorbs light and injects charge into a semiconductor, commonly a mesoporous oxide. Dye regeneration and charge collection complete the photovoltaic cycle.
What should I investigate?
Investigate dye absorption, redox mediation, recombination and sealing. Interpret impedance with a justified equivalent circuit.
07
Integrated & bifacial photovoltaics
Modules in their environment
Building integration, flexible formats and rear-side collection extend deployment choices. Irradiance, albedo, shading, temperature and mounting affect energy yield.
What should I investigate?
Compare annual kWh/kWp, thermal conditions and degradation, not only nameplate efficiency. Document rear irradiance for bifacial measurements.
08
Characterisation & modelling
Evidence before interpretation
J–V, EQE, impedance and transient measurements probe different aspects of device operation. Equivalent-circuit parameters depend on model assumptions and measurement conditions.
What should I investigate?
Use calibrated illumination and area, units and uncertainty. Do not infer doping density from Mott–Schottky plots without checking depletion assumptions and frequency/ionic effects.
CURATED READING & EXPLORATION
Resources with a purpose.

Compiled by NexSolveAI. Organisation summaries are based on official institutional and company pages checked on 18 October 2026. A check date records source review, not independent technical validation. Listings are a starting collection, not a comprehensive ranking.

Technical notes are introductory. Material energy values and device performance depend on measurement conditions, morphology and interfaces. Synthetic demonstrations must be identified as synthetic and are not experimental evidence.
